I can't recommend Dr. Mielke highly enough. I've been her patient for over seven years, and throughout that time she has consistently provided exceptional care. She is incredibly knowledgeable, thoughtful, and truly takes the time to understand the whole person rather than simply treating symptoms. I have always felt heard, respected, and actively involved in every decision about my care. What truly sets Dr. Mielke apart is her dedication to staying at the forefront of medical research. She is always up to date with the latest scientific findings and evolving approaches to patient care, and she thoughtfully incorporates that knowledge into personalized treatment plans. It gives me tremendous confidence knowing that my care is both evidence-based and tailored to my individual needs. She explains complex medical topics clearly, never rushes appointments, and genuinely cares about helping her patients achieve the best possible health outcomes. The entire team at Optimal Spectrum is also professional, responsive, and welcoming, making every interaction a positive experience. After more than seven years under Dr. Mielke's care, I can confidently say she has exceeded my expectations in every way. If you're looking for a physician who is compassionate, exceptionally skilled, and committed to providing the highest standard of modern, evidence-based care, I wholeheartedly recommend Dr. Mielke. read more

Dr. Mielke, both a conventional and functional physician, has been taking care of me for a decade and a half, ever since I was diagnosed with a lobular CA tumor so large that a single mastectomy was unavoidable. She expertly put me on a regimen of non-toxic compounds that she adjusts every quarter based upon her indefatigable updating of the advanced science on which she relies. She is both caring and direct. I credit her with much understanding and support and, essentially, keeping me alive while I avoided toxic recommendations from my more traditional team. The complexity of Dr. Mielke's patients means that while she has a killer memory and excellent medical training plus nearly a quarter century of running her clinic, she simply cannot know everything that will ultimately be the key to a particular individual recovery. For those dealing with autism, Lyme and similar tick borne illnesses, for supplemental information that may be really helpful to try, give the recordings from the Autism Health Summit 2025 a hearing (info@autismhealth.com). This will cost you $100 and access to a wonderful, intelligent support group to inspire your journey. read more

This review is long overdue. I was seen by Dr.Mielke from April 2020-July 2020 and then again from November 2020-April 2021. In total, I had approximately 9 visits either in-person or through a voice call. To her credit, Dr. Mielke did try her best to treat my ongoing mysterious symptoms; I have been unwell since late summer 2017. I do credit her for introducing me to a few things that were of help with chronic Lyme. She introduced me to the Relax Brand sauna, PlusCBD oil, and LDN. She also helped me understand that have a double mutated MAOA gene and cannot tolerate SSRIs.I thank her for these suggestions /prescriptions. However, by the last visit or two, I understood that she really did not know the root cause of my issue. She kept suggesting nutrition testing and practicing DNRS- neither of which helped to a large extent. In December 2020, she put me on a trial of herbs used to treat Lyme. In February or March, she put me on a full on herbal protocol. After 30 days, I did not feel markedly better. She pompously proclaimed, " Well then, it must not be Lyme. This protocol worked so well for so-and-so." I get the impression that she is not well-versed in treating Lyme. If she was, she would have ordered a CD57 test and used Vibrant Wellness labs to check a full spectrum of tick born illnesses. I'm sad that I spent this time and money not to feel any better. If you suspect you may have Lyme, be advised before selecting Dr.Mielke. read more

This is my second review on this business because I continue to use them for my Lyme Disease quarterly bloodwork and IGenex labs. This time, I'd like to focus the review on the excellence of the office staff and lab phlebotomists. Karina, Annette and Nancy are excellent staff and management, and reflect the greatness of Dr. Lynne in their compassion, intelligence, and likability. When I need to reschedule a lab draw because of flooding from bad weather or my own poor health, they are professional and understanding. That is one of many examples I can give of the outstanding service I continue to receive from Dr. Lynne's office. Thanks to Karina, Annette, and Nancy! read more

I used to come back in the past here for my son treatment. It was the real doctor that I met not the nurse. They suggested that my son get the b12 shot which made him shaky and nervous. And it was not even working, It was way back in 2016. I returned back now and thought that they had more knowledge in the field for autism but I was wrong. She still recommended b12 shots which nobody ever use this form of treatment. I paid 700$ for the appointment and was thinking about a good outcome. She handed me a big bag to get some tests done that was going to cost me $1000. And wanted to do a follow up after I'm done with the testing another $600. It's seems everything is about money than treatment. One test came and was requesting 150$ for 15 minutes appointment. That's ridiculous. read more

We worked with Sandy for our daughter's ADHD. Sandy cared only about money, and not to get the child better. So she will purposefully make the appointments long by asking unnecessary questions so that she gets paid more. I would recommend future patients to work with a provider who actually cares about making children better, instead of simply squeezing money from parents. read more

I can't express my gratitude enough for Dr Mielke. It. was only due to her diligence and thoroughness that my kid's pituitary tumor was discovered and we are finally getting some answers and hopefully help for many of the symptoms that he struggled with for years. We had seen many doctors before Dr Mielke, many psychiatrists, and none but she had the initiative to run the whole battery of tests, especially the complete hormonal panel that lead to this discovery. They've all chalked it up to depression and anxiety, without ever investigating for possible physical causes and just prescribing psychiatric meds. He could have suffered like this for years if not for her! I saw that some people might think that the tests she orders are excessive, but I beg to differ. Our experience just shows how important it is to have the whole picture! Dr Mielke and her staff are very professional, helpful and responsive to our various needs. Everything runs smoothly and is well organized in a patient's portal. The neurosurgeon that we saw recently, told my son that his doctor did a great job! We agree with that wholeheartedly! read more

I have been a patient of this office for over 3 years now. Dr, Kreizenbeck is extremely detail oriented and has helped me immensely. I would encourage anyone needing medical attention that most western doctors don't address to explore this option. read more

There's no way to match "I've seen 300 patients with weird undiagnosed things, and the ones resembling you responded to either x, y or z". Dr Meikie herself is particularly good- she listens well, and while being (and playing) the reassuring expert in the white lab coat, doesn't 'push' or 'bully', despite the position her skill and knowledge grants. Excellent care. If you are on the fence, please do. -------------------------------------------------------------- Integrative clinics are about helping out for chronic or poorly diagnosed illness. Check common 'fall through the cracks' medical failures, and in the process get you in the best shape you can be to fight off whatever the primary is. They, like all clinics of this type, need to pay rent. So, while they don't compromise on 'will it for condition x' do prefer treatments with good markup and profit margins. Yay economics! Don't fault them for this. We need the diagnostic capabilities too badly. So support them, and letting them make rent and make sure the diagnostic is right by letting them do the initial treatment. If it works and the cost and timeline works for you, great! If not, know that there might be cheaper, non clinical options. Regardless, these clinics are a Gawdsend, for being able to pointing you in the actual right directions. They are a smart move, and can save you time and money, in ways that no independent research path can match, read more

Dr. Mielke has provided alternative approaches to healing my ALS that I couldn't receive from other Western medicine doctors. Her knowledge and insight is second to none. Thank you, Dr. Mielke! read more

Dr. Mielke and NP Kreizenbeck are both lovely, compassionate, and knowledgeable practitioners of functional medicine. If you've gotten the runaround from traditional medicine and need a care provider who will listen to you, order appropriate testing, and help determine an appropriate care plan, then you should make an appointment at Optimal. This team has helped me with so many issues that were brushed aside by my regular physicians. I am much healthier due to the care that I have received at Optimal. read more

I feel incredibly lucky to have found Sandra. She has changed my life. I honestly was at the point where I wasn't living anymore, just existing and sleeping through the days. I had brain fog, anxiety, hormone issues, exhaustion, could not lose weight. I spent 2 years fighting doctors to run tests and begging them to help me, only to have them tell me I was "fine", or that I'm "just getting older". Sandra is the first person to really listen to me, believe me, and actually help resolve the issues. I feel like I'm me again. I appreciate that you can say no or pass on tests/ treatments that don't fit your budget. They really break everything down for you and are honest and forthcoming with prices. It has been worth every penny though, to finally get relief and feel good again. If you're struggling with your health and aren't getting answers, please think about making an appointment. I wish I had known about this place sooner. (All of the staff are amazing, by the way!) read more

We took my Granddaughter to Dr Mielke for ADHD. In one month there is a huge difference in behavior and happiness. The cost is negligible in comparison to the benefits. We would give up anything to come up with the money for the DR and the labs because nothing else has worked and we refuse to put a child on prescriptions. She is very thorough and seems to miss nothing. Please if you have an autistic child or a child with any behavior difficulties consider this Dr because a child deserves it. read more

Dr. Mielke at Optimal Health Spectrums is amazing!! It's taken me a little while to write this review because it's hard to believe how much my health has transformed under the care of Dr. Mielke. I started seeing her a few years ago after researching natural remedies for various health issues I was experiencing. My HMO primary doctor was just not going very deep and it felt like it was protocol to prescribe a pill for everything. Dr. Mielke listened closely to the issues I was sharing (migraines, insomnia, weight gain, brain fog, joint aches, digestive issues, exhaustion, etc) and recommended some natural supplements to start immediately. She ran full panels on food allergies, viruses, hormones, metals, etc. Dr. Mielke identified multiple health issues then worked with me on a combination of treatments and supplements to get everything balanced out. I started feeling better almost immediately after my first visit (insomnia was gone!) and I haven't had a migraine since I started seeing her. I continue to be amazed at how great I feel and how much better my quality of life is. As an added bonus, her entire office staff is so sweet and responsive. I never feel like just another customer, which is quite a difference from the HMO treatment I'm accustomed to. read more

I heard about the HCG diet program from a friend and from the general media - so I sought out an office that offered the true HCG hormone (and not some homeopathic knock off). After 8 weeks (two 3 week HCG runs followed by maintenance) - as of today - I have lost 30 pounds!! I for sure have now reset the way I eat and understand how MY body responds to certain foods. About the program, it basically consists of taking HCG and supplements every day for 3 weeks (and can do 2 - 3 week treatments back to back but then you need to get off the HCG for 8 weeks). I chose the injections as that is the preferred way to receive the HCG. Ok yup was freaked out by giving myself injections daily but you get over it quick. Really, pinching your fat hurts more than the needle. Are you hungry? A little bit but you drown those hunger muffles with water - essentially drown you hunger. The staff will work with you to find out what foods are working and which are holding you back. They have a set list of foods but just because its on the list does not mean it works for you. I loved the cottage cheese until i wasnt losing weight. So you tweak the diet along the way. The diet is not for the faint at heart- you need to be dedicated to yourself and the program, dedicated to getting rid of your fat pants that are getting too tight. I said I can do anything for 3 weeks - bring it! Side effects? While you are on the HCG, you are taking in very low calories. Headaches can occur and loss of energy but hey that scale keeps going down - so take a pill, sit down, relax and lose the weight. I also noticed that I lost muscle mass but thats because of the low energy and not hitting the gym (which you really shouldnt exert yourself while doing doing the program.) I hope this review helps. I would do this again but hopefully will not need to. I am continuing to lose weight now without the HCG. Do I dream about an In-n-out burger on top of a deep dish pizza, wrapped in a carnitas burrito with a krispy kreme on top? Duh! But whats the saying, (almost) nothing tastes as good as fitness feels. :) read more

Dr. Mielke and her staff are nothing less than amazing. I have been seeing Dr. Mielke for a couple of years now and she has been the only Dr. that I have found that spends a sufficient amount of time with you to really listen to you and get to know you and your issue. She has been able to help me manage numerous health problems that I have been dealing with and that other Dr's had been unable to help with. It is so refreshing to find a Doctor that really cares. read more

(This review is "not recommended" by yelp, but it's a real review by a real former client. I keep a separate yelp account for my medical reviews because these experiences are personal and I don't want my friends and family reading about them.) This clinic is very well-run. The staff is excellent, polite, helpful. The services provided are excellent, including an IV room with well-trained nurses and phlebotomists (very few clinics are equipped with an IV room). There's even an in-house pharmacy for the compounded meds Dr. Mielke prescribes. The medicine practiced here is sophisticated and cutting edge. I never had to wait for my appointments, the doctor was always on time. She provides handouts explaining in detail the various treatments she recommends and/or prescribes, which is helpful. My problem over the course of many visits was with the doctor herself. I found her to be condescending and I didn't feel comfortable with how she communicated (without revealing too much information on yelp). Some visits were better than others, and she's a smart and, overall, caring doctor (possibly more caring towards some patients than others), but I think it's important to feel comfortable with someone who's treating you for complex, chronic health problems, and she just wasn't the one for me. I've since found an equally knowledgeable doctor who has better communication skills and treats me as a partner rather than just a patient, who values my knowledge of my body and doesn't feel threatened by information I've picked up from my own studies and research regarding my health conditions. When you invest *so much* time and money in a doctor (especially after that expensive first visit), you sometimes ignore the clues that there's a communication problem and forge ahead. But it really is worth it to stop if you don't feel comfortable and try again with the next person. read more

I live in Hayward and believe it or not I have a hard time finding a place to receive a vitamin B12 shot. Most places try to scam you for a consultation in this area which I refuse to for a water sociable injection. When I showed up I was in and out in 10 minutes, plus the quality of the B12 they use here is amazing. Effects last up to a week no problem. read more

Dr. Mielke and staff have done amazing things with my health and looks. As a physician, Dr. Mielke took me through long term Lyme disease and was instrumental in restoring me to health. I cannot give enough thanks to her for that. I highly recommend Dr Mielke for severe health concerns. Since my recovery, Kat has taken me through laser treatment with great results. Her knowledge and caring treatment have been amazing. I have complete faith in the recommendations she gave as I asked for her help in cosmetic areas of concerns. Very professional . Her nursing skills show through. Thank you Kat and staff. read more

Dr. Mielke and her staff are excellent! I have been a patient here for 9 months, and even a 5 star review does not adequately express how highly I recommend working with these professionals. Having worked with both mainstream and alternative practitioners for the past 20 years trying to address multiple overlapping health problems, I have extensive experience for comparison. Here's why Dr. Mielke's approach won me over: 1) She asked for my COMPLETE health history, not just the thing that was bothering me at the moment. She required that I turn it in ahead of my appointment so she could read it. What a concept! A doctor who wants to know about my health! 2) Every appointment I have had with her, I feel like she devotes plenty of time to listen to me, ask me relevant questions, and give me information about what to do next. I feel like she is including me in making decisions about which diagnostic tests to do, deciding which supplements I should take, and considering how much time to wait before checking on my progress again. 3) Her recommendations actually work. I have dealt with chronic pain since childhood, as well as chronic fatigue, rashes, migraines, unexplained numbness, and a myriad of other issues. Other doctors have told me it was all in my head, just stress, or maybe I needed to quit my job. Alternative practitioners could help me with the pain, and some supplements seemed to help in the short-term, but nothing seemed to address the comprehensive situation. Dr. Mielke ran a series of diagnostic tests that made me confident we had explored the possible causes, we agreed on a treatment pathway, and I have continued to feel better and better every day since I began seeing her. She has demonstrated both extensive expertise, as well as maintaining an openness to new treatments that have evidence to support them, even when they may not be widely accepted by others. I highly recommend working with Dr. Mielke and her staff. Their work is well worth the cost of services. read more

Dr. Mielke is so knowledgeable in putting together a specific health plan designed especially for you. Through detailed blood work and lifestyle/environmental analysis she's getting my health dialed in. It's expensive, but I'm worth it! read more

My son has been in Dr.Mielke's care for almost a year now. I have nothing but good to say about her and her entire office. My son wasn't talk or making eye contact early this year and now he won't stop talking and understand what adult asking. I always communicate with the staffs for everything (appointment, medicines needs, questions for Dr. Mielke and all other inquiries) through email or phone and they get back to me very quickly. Never had any problem, they always understand with my situation and my need as a single and working full time mom and they are very caring. I can never asked for more, they are the best thing ever happened to me and my son's life! Thank you everyone from the bottom of my heart!! read more

If I could give 0 stars, I would. They sure are solicitous when they're taking your thousands of dollars, but don't ask for any of the personal information in your file. Unless you are writing a check, usually very large, the customer service is non- existent. Even that I could handle if the Dr. did anything whatsoever to actually help me. Would NOT recommend unless you enjoy throwing your money away. read more

I made an appointment with Dr. Lynne Mielke, and she didn't even show up. A nurse talked with us, and I didn't get much info from her and was charged $300 for this trip. We were pressed by this office staff to do blood test, and I requested them to email us the blood test result but they refused. I was told we need to make another appointment to see the report, even though we paid for the blood test. If it was disclosed to me that a substitute would see us, I would have never go there. This doctor's goal focus is to make money instead of helping patients. read more

Dr. Mielke and her staff solved the mystery of my girlfriend's son's debilitating health issues, when no "standard" western medical doctor could. I've been very impressed with their thoroughness and friendliness. As a result of this, when she was recently diagnosed with cancer, she knew where to turn to get a different type of care than she was getting from her standard physicians. I greatly value the integrative approach. The Dr & staff are friendly, professional and knowledgeable. I would most definitely highly recommend them & their services! read more

It's only a mild exaggeration to say that I owe Dr. Mielke my life! After seeing MANY Drs, spending thousands of $$ and far too many hrs, I'm finally making progress back toward total optimal health! Hallelujah! God Bless you, Dr. M! I read some of the bad reviews. I get it - but give her and her staff a chance. You'll be glad you did, esp. if you are really sick. This woman will get to the bottom of it! By the time I found Dr, M., I was an absolute wreck, spending 70% of my waking hours in bed, weak, exhausted & in pain. I had to quit working. I simply couldn't function. Everything hurt (muscles & joints mostly)! I'd lost 1.5 inches ht over the course of the 2yrs prior. I went from being a gumby/bendy athlete, to moving like the tin man after a rainstorm - "oil can!!" I was waking up several times during the night, usually because of pain, sometimes because of severe heart palpitations and occasionally because my bed was shaking - turns out I was having seizures. I finally woke up during one of those ... whole body shaking while I was completely paralyzed, unable to scream, cry or move, while it seemed like electrical storms were going off in my brain. It was TERRIFYING! Sometimes when I woke in the morning, my right hand would be frozen in a 1/2 clenched position & tingling. When I was able to sleep, it was on top of several gel ice packs, which I had to rotate from the freezer during the night, at the intervals when I got up to take more anti-inflammatories (about every 3hrs). I was really suffering, and every mainstream, western M.D. I saw dismissed, diminished and discounted my thoughts, observations & comments. They just kept trying to slap a convenient diagnosis on me (so they could get paid by insurance co) and threw more drugs at me. Nothing helped. One of the drugs left me with constant ringing in my ears. Yeah, thanks, Mr. Rheumatologist- diagnosed me w/ RA, even tho' bloodwork was neg. & joint pain was only on one side. Wanted to put me on super toxic RA drugs. "I don't have RA, ya DB!" He was the worst! I also saw Naturopaths & an Integrative Med Doc in Marin. All came highly recommended. They provided some clues & some interesting test results. But they missed SO much - even in the results of the test they ordered. I found more answers @ the tests on Google than some of these Dr.s knew. But when I brought those results to Dr. Mielke, she got the whole picture immediately! She was up on everything I'd dug into w/ my research & was able to explain and enhance my understanding. She never dismissed my ideas, inquiries nor my challenges. She met them all with respect. Sorry I know this is long. Re: the negative reviews - I was skeptical (& desparate) when I 1st came to see her, and I too was feeling defensive @ everything from how much she charged, to how she & her staff came across when answering questions. Let me say, when you're feeling poorly, it's easy to take offense where none is intended - I did, at times. But they were always quick to apologize or clarify. As I got to know her better, I came to understand that Dr. Mielke tries to be very efficient with your & her time, to get you as much info during the time your paying for. No pussy-footing around. I came to respect & appreciate that very much. As for comments that she's condescending, etc. - I experienced a little bit of that too. In hindsight, it was very minor & was exaggerated by my perception at the moment 'cuz I felt like complete crap, like I wanted to die. Whatever skill she may lack in tenderly wording things, she more than makes up for in results. No one's perfect. She's very good at what she does. In my book, she's earned some grace. And she really DOES care. Anyway, she was THE ONLY Dr. who found clear evidence of chronic Lyme, now active & wreaking havoc. I was bitten by a tick in 1990, found the tick, had the bullseye rash, etc. I didn't get diagnosed til. 1991. Thought I'd beaten it, but apparently it only went into remission. Here's where my story gets a little out there ... I'm a clinical hypnotherapist. I see amazing things w/ my clients, via the wisdom of the mind/body connection, etc. Finally, one day (before Dr. M) it occurred to me - DUH, put myself into hypnosis, ask my body what it's fighting. So, I did. Boom! - I saw my 1990 bullseye rash, then Boom! - I saw the tick I found in my bed in 1990. I hadn't thought @ the Lyme in yrs! But there it was. It all made sense. So, I went to my GP (knew my whole history), who immediately dismissed it, but agreed to give me a highly-inaccurate, cheap Lyme test (only one insurance covers). Of course it was neg. - common w/ chronic Lyme. GP then sent me to the A**hole Rheumatologist & my 2yr wild goose chase began. When I found DR. M, my nightmare finally came to an end (I didn't know it right away tho). Dr. M. believed me. She found the Lyme w/ a CD57 test (I'd never heard of it). It's been 8mos. w/ Dr. M. I now sleep 8hrs, 85% pain free, getting better day by day! read more

Thank goodness there are Dr.s as good as Dr. Mielke. She took nothing for granted, unlike my HMO provider, and ran appropriate tests that identified my issues which were not trivial including stage 3 adrenal fatigue and breast cancer. She caught them early and therefor we are able to address both before they become a medical crisis. I was feeling tired and unable to do what I use to be able to do. I thought it was old age creeping up on me fast. What a relief that Dr. Mielke knew that being tired might be a sign of an underlying issue. I highly recommend Dr. Mielke and all her staff for their kindness and patience especially since people with adrenal fatique can tend to make mountains out of molehills. read more

To whomever is reading this! Be aware ! This doctor and her group are a bunch of frauds! Everything she said I had -I didn't have and was proven negative by my own doctors and allergist! And specialist! Some examples- She said I had Lyme disease and I was tested again by professional hospital and it was negative. She said I was allergic to gluten and dairy and everything I ate that day. It all was negative and proven by my allergist. She said I was an alcoholic and Ive never ever been drunk in my life or do I drink. This doctor was so unprofessional, she should be ashamed and shut down and put out of business!!!!!!!!! Don't ever go there! You have been warned! read more

Hi, I just wanted to relay my experience with Dr. Mielke and her staff over the last year. I have experienced severe migraines for over twenty years. I have been seeing a neurologist over this time also, to "maintain" them, but it wasn't going well - in fact it was getting worse. Dr. Mielke has completely changed everything for me. After running extensive blood & lab work, she started with what I was putting in my body. Dr. Mielke changed my vitamins & supplements, my food, you name it. After a couple of months, (it isn't an overnight cure!) there was an improvement for the first time, AND it hasn't stopped. I am still getting better every month - I am off almost every prescription drug that has been prescribed to me and I can't remember taking an Excedrin for a headache. That is after going almost every day taking 4-8 daily just to get through the day. I could give you a whole other list that went with the migraines that was debilitating with it, but let's just say - It's all good now! I can only wish this opportunity had come along in my life so much sooner. I love the staff, they treat me wonderfully. Yes, I wish my insurance would cover a lot more of the expenses, but to me, to finally feel this way in my life is incredible. Shame on insurance companies for paying for people to be on RX drugs, instead of vitamins & supplements, etc..... I feel many people could benefit on seeing what is going on with their bodies with this fantastic lab tests. Next will be my family! read more

Right from the start the staff were friendly and efficient. Each time I called, I got straight through to Missy, who is very knowledgeable, personable, and capable. The new patient coordinator, Adrianna, seemed to really care that I had a smooth experience and took time to check back with me to see that I had all my questions answered. Dr. Mielke addressed all the issues I had on my mind. She presented options for tests, supplements, and therapies, but she left the decisions up to me and didn't push treatments or procedures that I was reluctant to start. She was congenial in the way she presented it all. At first she seemed a bit stiff, but I attributed that to the fact she really knows her stuff and is intent on getting her message across to the patient. One of the most important features for me was that Dr. Mielke read my health history and past lab reports beforehand. So she already was thinking about what to work on. That saved me time and money by not having to explain everything in detail during the office visit. For my blood draw, Rolando was the best phlebotomist I've ever come across. My veins are small and will collapse. But he had several personalized techniques that helped my veins pop out and hold up for six vials. Nicole very patiently explained the paperwork and billing to me. So kudos on a fabulous lab as well. read more

Dr. Mielke was able to diagnose me with Lyme Disease as well as the Lyme co-infection Babesia. I am thankful for her insight and determination to pursue my diagnosis. I have been doing Ozone treatments through her office. These treatments have made a huge difference for me, as a part of my Lyme treatment plan. And might I add...the staff in the lab are wonderful people! read more

Dr Mielke really keeps up- to date on all the newest advances in health care for the brain and the entire body. Most doctors don't do that.

Began seeing the dr. 3 years ago, I'm a different person thanks to her! She was very thorough in her initial intake meeting with me. Test results were prompt and now three years later, after consistent use of supplements and changes that she recommended I am more energetic, and healthier than I was. I would recommend her to anyone. read more

Very helpful good service........... ............... I'm 3rd time here doctor and all staff are all helpful read more

Dr. Mielke, Nurse Practitioner Sandie and her staff do amazing things at this clinic, there is a variety of natural paths you can take here at Optimal Health Spectrums to get your health back on track. She does a list of amazing things but some of the coolest things she does are: IV Ozone Therapy, IV Nutrients, HCG, Sculpsure, a variety of Laser treatments which are done in the MediSpa department and are well priced and affordable! Many more things done at Optimal Health Spectrums. Highly recommended for everyone not just people who are feeling ill but also for if you want to just get work done on yourself and treat yourself to some of the variety of Lasers done in the MediSpa or to get Sculpsure done. Very unique and amazing place highly recommended. read more

I have worked with Dr. Mielke and her staff for over a year. I have found that Dr. Mielke's science based approach to autism treatment is consistently helpful for my son. Also, Dr Mielke's staff has always between extremely helpful, drive a very caring approach to the young patients, have always followed up on questions/inquiries on the same business day, and proactively sent test results to me in advance of my meetings with Dr. Mielke. I will note, I have had issues with the pharmacy *on occasion* but have always had immediate followup with Dr. Mielke's staff in these situations. read more

I am in desperate need of help with hormonal imbalance. I was excited to find Dr. Mielke until I set up an appt and discovered that her first visit is $300 for only 30 minutes! How you can cover a NEW patient's entire health history, especially in light of how complicated hormones are, in 30 minutes is beyond me. I cancelled the appt because it seems this Dr is more interested in making money than helping patients. read more

I found Dr. Mielke to be very condescending and full of herself. I have Hashimotos and was trying to seek help. Dr. Mielke was very rude about my weight (one of the reasons I was seeking her help). She obviously doesn't like tattoos as she said "you are covered in those things". In reality, I have six tattoos that are not large and she only saw three of them. After paying a little over $500 for my first visit including supplements, I was told I could contact her with questions. I emailed the Dr. With questions and when I received my response several days later, it was one word responses in red. I decided to go back for a follow up and listened to her brag about her autism success. While I think this is fabulous work, I'm paying her to take care of me. I had a reaction to something she gave me and emailed her with questions. Her response was, " I don't know what you are having a reaction too, just stop taking everything" that's it! No other followup or phone call. read more

My experience with Dr. Mielke was a nightmare and an emotional roller coaster. She did not follow the recommended CDC protocol for Lyme disease testing from IgeneX. 1. The immunoblot should not be run without first performing an EIA or IFA. 2. The immunoblot should not be run if the EIA or IFA tests are negative. 3. A positive IgM immunoblot is only meaningful during the first 4 weeks of illness 4. If you've been ill for longer than 4-6 weeks and the IgG immunoblot test is negative, it is unlikely that you have Lyme disease, even if the IgM immunoblot is positive. She skipped the first two, jumped straight to IgM which was positive. (I had no knowledge of a tick bite especially within the last 4 weeks.) I found out after leaving Dr. Mielke's care, through my own yearlong research that you can have a false positive if you have another bacterial infection. My dentist scraped a sample from under my gums, placed it under a microscope and we viewed it on a computer screen. He said you see those, they are Spirochetes. I'm like, really. I've been tested positive for Lyme (a type of Spirochetes). After that, I immediately asked my NP to order test IgG (4). Bingo! Negative! Secondly, with Dr. Mielke, I agreed to a non-FDA approved ONCO Blot early detection cancer test. I think, "Sure, I'd like to know that early enough to do something about it." When the results came back, Dr. Mielke calls me and says, "I'm sorry but, you have breast cancer." (It was like getting hit by a truck!) I follow her recommendations; in a panic, I immediately schedule a mammogram. I show them the ONCO blot test results, (which no specialist, even from Stanford, has ever heard of.) The radiologist decides to do a 2D, 3D and ultrasound. Nothing shows up. Come back in 6 mo. for more radiation. My GP says get a second opinion and refers me to a breast cancer specialist who recommends an MRI. My insurance company won't approve the MRI. Dr. Mielke says, it may be too early to detect by MRI anyway, call this NP in Indiana, she has a protocol that may help (again not FDA approved, don't get me wrong, I believe in holistic treatment). So I call her. She talks to me for about 1 hr. while talking to her grand-daughter in the back ground-very unprofessional. She reassures me that she is going to guide me through treatment and re-testing and consulting with Dr. Mielke. After repeated phone calls and emails to the NP (even cc: and called Dr. Mielke), nothing, never heard from NP again. I went to Dr. Mielke in the first place for bioidentical hormones, which now no doctor wants to prescribe because I supposedly have breast cancer. Great! So, the breast cancer scare will stay on my mind forever if it shows up or not. Thankful, I can put the Lyme misdiagnosis in the past. I started exercising more, trying to eat better and I've been doing great! After a butt load of money, time and stress; the only thing Dr. Mielke did for me is to scare me into taking my health more seriously. With that comes stress, which is worse? For that, I give her one star. Now, she offering people a $25 credit for a Yelp review! (BTW, her staff was excellent!) read more

I have worked with Dr. Mielke for years. She is a great doctor for someone who has chronic health issues and wants to get deeply involved in a real partnership with an MD who listens and is able to think out of the box. read more
