I highly recommend Dr. Steve! I originally came to him to help with symptoms of an autoimmune disease, & he ended up fixing multiple other things while at it. He offers many different types of services for whatever you need. He is communicative & easy to talk to. I highly recommend! read more

Dr Steven Hyjek of The Functional Medicine Center is the BEST doctor of Chiropractic care that I have seen! Not only is he extremely knowledgeable of the human anatomy, he uses high-tech equipment to enhance treatment and accelerate healing. Ask about the micro-current and laser treatments, they are GAME CHANGING! I have had lower back pain, and other back related issues, for over 20 years but after seeing Dr Hyjek I can almost envision a life without constant pain. My lower back pain would cause sciatica pain through my legs, sometimes so debilitating that I can't move, go down stairs, or drive to work. His adjustments and using the micro-currents and laser therapy have significantly improved my lower back pain and movement. But it's not just about the technology, Dr Hyjek can pinpoint the exact area and "pop" the pressure if you let him know the general area that's especially causing pain. He literally can do this with one finger!! He truly is a miracle worker when it comes to chiropractic care; I highly recommend Dr Hyjek! read more

I've been going here for the last few years even after I've moved to Brea which is now a 45min drive. Dr. Hyjek is seriously the best chiropractor I've ever been to. I've tried a handful of others but none of them are as good. It's his gift. He barely puts a finger on you and already knows all the pain points. He's the most gentle I've had too. Super good with his hands and techniques work. I would go in with a 9-10 pain and after a few sessions it would completely go away. He's amazing, not worth looking for any other chiropractor in town. Also customer service is awesome, always very helpful and friendly. Answers right away read more

I had been dealing with unexplained symptoms (hair loss, severe fatigue, dizziness, stomach issues bloating/bm, acne, etc.) for two years. My Gp and other specialists kept telling me I was fine. I suspected I had Hashimoto's but they kept saying my labs were normal. In the 6 months I worked with Dr. Steve he was very attentive to all of my symptoms and worked with me to really understand what was going on with my body. We went step by step when it came to fixing the problems. I feel so much better than I did before. My fatigue has improved, I barely have stomach issues (we discovered in addition to my dairy intolerance I had a gluten intolerance), my dizziness is non-existent, I am more conscious about getting enough protein with my meals and ensuring all of my vitamin levels are more than just fine. My thyroid antibodies before i started were 3 aka high = bad!! Now they at 1 which is the normal range for thyroid antibodies. I'm so grateful for him and I plan to continue following our plans we developed and checking in with him yearly. Trust me I grew up believing only in western medicine and side eyeing people who swore by supplements and sunlight. BUT It really works! I wanted to avoid taking hormone replacements for as long as possible so thats why I chose the holistic route. I DO NOT regret it AT ALL! read more

Dr Steve is extremely thorough and attentive. Within 2 weeks of the treatment plan he gave me I saw great results. This is the first time I have consulted a Functional medicine Dr and I am so glad I did. Each time I visit the office I donot have to wait and my time with Dr Steve is very focused and intentional. Highly recommended! read more

I've been working with Steve for the last at 2 years at least! He's helped me so much with my thyroid and I appreciate how he listens and really tries to find solutions that work and also stay in my budget. But nothing compared to how he helped my daughter this last year. My daughters health dramaticly declined and the medical system constantly failed her. Steve did test after test trying to help us figure out what's going on . In the mean time he recommend supplements to support her body which has actually made her feel 85% better then she has felt in a year . I'm so grateful for his help and would definitely come to him over a traditional dr any day !! read more

Where do I even start? If there was a sixth star Dr. Steve deserves it. I've been going to The Functional Medicine center for years, and it has NEVER failed me. My abhorrent posture was fixed due to Dr. Steve's expertise and plan, which resulted in better performance for my sport. Not only that, but the pain I had in my hips and back were fixed. The Functional medicine center prioritizes healing by targeting the root cause of your illness, disease, or injury. If you're tired of being prescribed medicines or treatments that only mediate your symptoms and don't solve the underlying issue, then Dr. Steve is who you want to talk to. I recommend the functional Medicine Center to people of all ages, backgrounds and walks of life. Dr. Steve is kind, caring, supportive, genuine, and understanding. When you walk into his office, you know that you're not just another patient for him to work on, you're someone he truly cares about and wants to help. read more

If you're considering to give a try to a chiropractor or you're done with back pain I highly recommend Dr. Hyjek. I have dealing with back pain since my 20s, I have being on and off with different painkillers. Before I met Dr. Hyjek I used two over counter painkillers and famotidine to protect my stomach. I am in my fifth session and there's a big improvement. I am not taking pain killers and the pain has reduced in more than 90 percent. I am doing the exercises Dr. Hyjek recommended and attending to my adjustment sessions. The office set up is very clean, comfortable and welcoming. The staff is very professional and kind. I can't recommend The Functional Medicine Center enough. Now is up to you to give it a try. read more

I was referred to Dr Steve by some friends in the fitness industry and Lord I'm so thankful for the referral. Entering Dr Steve's office after hours due to full time father scheduling was welcomed with a smile. After a silly mountain biking accident on the 4th, I was left with what I believe is a fractured or cracked rib, and some really gnarly abrasions on my shoulder, scapula, and ribs. Although doing my best to wince through the pain, Dr Steve helped me immensely with his laser treatment, massage and adjustments that had me back on the bike in no time. Thank you Steve for restoring my mobility and getting me back on the bike. I'll definitely be coming back. read more

Doc Steve is getting me back to health after a diagnosis of Hashimoto disease. I have been able to stay off cholesterol, thyroid and testosterone medicine with diet change and supplements. read more

Dr. Steve has been caring for our now 22 year old son for approximately one year for unresolved, chronic nightime nausea (with resulting sleep deprivation) as well as back and shoulder pain from his years playing water polo. We visited countless specialists for the above conditions for nearly 4 years with no clear diagnosis or effective treatment for either (besides prescription meds or surgery). I am pleased to report that after participating in the functional fitness and chiropractic courses of diagnostics and treatments, he has improved tremendously and experiences only rare nausea episodes and his back pain is now manageable. As a mom and nurse, I am so grateful for the care option that Dr. Steve's center provides. read more

If I could give The Functional Medicine Center more than 5 stars, I most certainly would. And let me tell you why... The onset of me first becoming sick occurred in April of 2017. The first round of symptoms were subtle- things like fatigue, headaches, irritability. I didn't think anything of it until it got worse- digestive issues, massive brain fog leading to major cognitive decline (the worse symptom), shortness of breath and everything went downhill from there. I can't tell you how many doctors i went to the first year this happened. I went to doctor after doctor. I remember my first visit to the emergency room the first short weeks this all started. The doctor assumed it was due to anxiety and was going to prescribe me anxiety medication. Are you kidding me? I'm over here telling the doctor my lungs feel tight and that I can barely breath and he writes me a prescription for Xanax. No thanks. I didn't give up there. The next doctor said I have asthma/anxiety. Didn't believe it for a second. They based this off no real tests. It became a guessing game. But desperate, I took inhalers after inhalers and rounds of prednisone. No difference. It only made me feel incredibly worse. Next doctor believed I had pneumonia and prescribed me antibiotics. Desperate again, and feeling hopeless at the time, I took several rounds of antibiotics. Did not help. Similar stories followed for years. No doctor that had a real solid corrective plan. After so many doctor visitations I became an expert at interrogation. I wasn't going to trust just anyone with my health. My health was bad enough as it was, but doing it on my own for the last 3 years, I was better off on my own than the first year under several doctor's care. But then something prompted me to look into a Functional Doctor. I came across The Functional Medicine Center and scheduled my initial consultation. Within the first couple appointments alone, with proper testing Dr Hyjek was able to pinpoint exactly what was going on. I was so relieved, after 4 long years, I finally got the answers I was searching for all along. I'm so glad I gave him an opportunity because 1 week into starting the treatment, my long battle with brain fog is lifting. THAT WAS THE WORSE SYMPTOM OUT OF ALL. I'm so grateful to have my brain back again and SO glad I sought treatment at the Medicine Center. Dr Hyjek is truly passionate in his work and is just the kindest most sincere doctor I personally have ever had the pleasure of meeting. I will be sending many referral his way. Thank you Doctor. Thank you for listening to me and believing me, and not thinking I'm some kook. read more

Dr Steve is excellent. I would recommend him to help solve chronic health issues. I have seen numerous doctors over the years that were not as successful. Dr Steve has a lot of great tools and very good intuition to help me find my main causes of my health issues. I feel I have made great progress in a very short period of time and now I am on my way to long term good health. read more

I was 7 months pregnant when I went to Dr Steve Hyjek for the first time. My sciatic nerve and lower back were causing me such pain and discomfort that it made it difficult to walk. The pain just made me feel miserable. A couple of our friends recommended Dr Hyjek. After getting adjusted I felt so happy! I had totally forgotten how it feels to walk pain free... it's awesome! I was so happy with the results that now my whole family is seeing him regularly. Our little son was 4 days old when he got his first adjustment. And our girls (7yrs and 3yrs) love going to "Dr Stevie's" office. I would highly recommend him, especially anyone with any aches and pains, or just wanting to maintain a good overall health. read more

Transformational. Yes, really! I was searching for a Functional Medicine doctor and found Dr. Steve in the listings for IFM Practitioners. Even better, he was also an approved Chiropractor through my insurance. The opportunity to create a relationship with a FM doctor and chiropractor is exactly what I have been needing. I came into his office exhausted with aches all over, a stiff neck and tight shoulders, daily headaches, vertigo 3-years running, chronic fatigue for over 20 years, brain fog so thick I wouldn't want to get out of bed, and some major gut issues. Basically, you could call me a hot mess. In May 2017, I started a 3-month intensive chiropractic plan, going 3x per week. I remember saying to him that I wonder if I'll ever have a response of "I'm feeling great!" to his sincere questions of how I was doing. During the course of my visits, I was feeling a little better, with the aches and stiffness beginning to subside. He has always been patient and willing to answer so many questions I had. I began taking a few supplements he had recommended and continued on with my chiro appointments. By the end of two months, I had a MAJOR breakthrough in my health. Wait, what is this I'm feeling??! By the 3 month point, I'm noticing: my head is clear, my headaches were gone! I'm experiencing a level of energy and conscious awareness that I have never felt before. I asked him: "is this what healthy people feel like?!" and (happy) emotions would surface as I expressed my thoughts. These changes initially brought disbelief. Ah, perhaps its a fluke and it will all come back with a vengeance. But the improvements kept coming and I was starting to believe it has actually taken hold. So it's now been 3 solid months of improvement. I've accepted and realized that this is indeed NOT a fluke and I am well on my way to a level of health I have been yearning for. I am continuing chiropractic care with Dr. Steve and now plan to also incorporate his Functional Medicine expertise to help me continue on this amazing path and start working on additional deep-seated issues that need the boot. I can't wait to see what the future holds and see how high I can fly! Thank you, Dr. Steve, for your guidance, support, and compassion and your knowledge that you share with those of us who need it so much. I am beyond thrilled to have found you...I can't express how much it means to have someone who works WITH you, as a partner in health, rather than experiencing a rushed appointment with another and hoping they GET it. YOU GET IT. Thank you for that. read more

I had been struggling for a couple of years with horrible headaches and just overall not feeling well. Then I started getting deep muscle aches that felt like they were going to my bones. I kept gaining weight no matter how hard I worked out or what diet I tried. I felt miserable! I went to numerous doctors and they all told me I was fine. One even told me I simply needed portion control. I purchased a book about how to heal my thyroid naturally and the author mentioned functional medicine. Magically Dr. Steve was close to me. I made an appointment and was instantly impressed with his knowledge and the fact he actually listened to me and did not dismiss anything I said. After multiple tests Dr. Steve figured out the problem and got me started on a diet and supplements to start the healing process. I will admit sticking to it was not always the easiest, but I am sure glad I did. I have never felt better! I am able to workout again and see progress. I no longer feel the need to nap during the day and rarely have a headache. Please go see Dr. Steve today! read more

I honestly cannot say enough good things about Dr. Steve Hyjek. I came to Dr. Steve about two months ago with a new diagnosis of Hashimoto's Thyroiditis and a diagnosis of Polycystic Ovarian Syndrome that I'd had for years. I was experiencing numbness and tingling in my face and hands. I was putting on extra weight although I hadn't changed my lifestyle. My energy was so low that I constantly needed a nap--and a lot of caffeine. I constantly felt like my brain was foggy and it was hard to concentrate. I had chronic neck pain that three other chiropractors and regularly massage therapy had done nothing to alleviate. I had bloating and digestive issues. And I was experiencing high levels of anxiety even though my life was relatively calm. Frankly put, I was a mess. Dr. Steve was very thorough in the tests he conducted before treating me--and I really appreciated that. Because of his thoroughness he discovered I had a parasite (yikes!) and a condition known as Adrenal Fatigue in addition to my Hashimoto's and PCOS. He also noticed my head was positioned an inch and a half forward of where it should be causing it to put 30 pounds of pressure on my neck (no wonder I had chronic pain!) Within 30 days of beginning treatment with Dr. Steve, my head was successfully moved back half an inch, reducing the pressure on my neck noticeably. My brain fog was completely gone, my anxiety greatly reduced, my numbness and tingling almost non-existent, and my energy levels so improved that my husband actually looked at me and said, "It's so nice to see you being who I always knew you were inside." I'd lost some weight too--and felt like an entirely new person in many ways. Because of the extent of my ailments, I will still be seeing Dr. Steve for a long time to come. But I couldn't go another day without singing his praises because after such a short amount of time I'm already beginning to feel better than I ever thought I could. If you're thinking of giving him a call, don't hesitate. Do it right now. read more

Years of chronic fatigue and pain syndromes are vanishing! After seeing dozens of doctors and specialists, none of them helpful, my diagnosis and treatment from Dr Steve has absolutely been the best head and shoulders above the rest. I feel 25 years younger! read more

I am relatively new to the area and found Dr. Steve during a search for a Functional Medicine practitioner in Orange County. I worked for more than a year with endocrinologists, my GP and endured lots of tests. I was finally diagnosed with Hashimoto's and honestly these traditional practitioners were unable to help alleviate any of my symptoms. As a 53 year old woman, I came to Dr. Steve with chronic joint pain, low back pain, general edema, fatigue and insomnia. Within a couple of months I was close to symptom free for the first time in over 2 years! His approach to diagnosis and treatment was clear and easy to follow. I've always been skeptical about using supplements, but I can actually feel the benefits of the treatment program I've been on. I also appreciate how open to feedback Dr. Steve is - he doesn't force a particular approach if it isn't working for me. He is very well read and always seems headed to the latest training or is talking about some recent research that could have bearing on my treatment. Finally, I'd just like to say that Dr. Steve is one of the nicest people I've worked with in any capacity. I couldn't recommend him more, whether it's for a routine adjustment or a full workup. read more

Dr. Steve has been my doctor and chiropractor for almost 5 years now. I highly recommend him because of his wonderful and friendly bedside manner. He listens to his patients and he doesn't sell on things you don't need. He sells excellent products that I continue to purchase and his treatments are spot on. Dr. Steve treats patients with pulled muscles, aches and pains, high cholesterol or blood pressure and more issues. He will take good care of you. read more

I was very enthusiastically referred to Dr. Hyjek by a friend who was a former patient of his. I started seeing him in Oct. 2017 to treat several chronic health issues. He is extremely thorough & goes out of his way to explain how treating such issues is like peeling the layers of an onion. Well it's taken a lot of work and a lot of patience but he has been there every step of the way to explain & to encourage. I can honestly say I could not be happier with the results. Functional medicine is definitely the way to go & he represents the best of them. Thank you Dr. Steve (& Jen)! read more

The best Doctor ever! I've gone to Dr Steve for many injuries mostly from my workouts & he always within minutes can patch me right up. My husband & I managed to get our parents to come see him & they love it! Very knowledgeable & caring. You can't go wrong by coming here. read more

I visited Dr. Steve due to ongoing jaw pain, headaches and an overall wellness check. He recommended a treatment plan that had me feeling better almost immediately. Not only did he treat the physical systems but we made some great nutritional and dietary changes. In a very short period of time he had me feeling like a new person. read more

He makes me laugh, and fixes my back what more can I ask... Always feel great after leaving his office. Dr Steve - here's your gold star ;) keep being amazing. read more

I found Dr Steve after I was diagnosed with Hypothyroidism, and all I got from conventional medicine was a daily pill (that I refused to take) based on a standard blood test that didn't even show whether I had Hashimoto or not. Nobody was interested in figuring out what caused my symptoms and treat the root cause, which to me should be the purpose of medicine, right? Thankfully, the internet introduced me to the notion of functional medicine. Dr Steve made me do a dozen tests that looked at what seemed every function of my body - an extremely important step because Hypothyroidism can be triggered by a huge number of issues. Medicine as it should be! And the results were astounding, which again proved the necessity to find the cause of the problem and not rush and mask the problem with a pill. I had problems with no direct symptoms pointing to them, so there was no way for me to ever know I had them unless I found a doctor who knew how complicated Hashimoto triggers could be. I keep going back to this point. He actually took the time to test all the possibilities! It has been a little more than 3 months now, and my symptoms have either vanished or been reduced to a random barely noticeable annoyance. My main symptom was fatigue to the extent that I couldn't get up in the morning. This was the first symptom to go away. I sleep the same number of hours, but now it is enough, the need to constantly nap is completely gone. I couldn't be happier with my progress. And while I still visit Dr Steve on a regular basis to take care of the few remaining symptoms, there is no doubt in my mind that my choice was the right one and I found a great doctor! read more

I was a patient of Dr. Hyjek in Minnesota and he is great! I had been to several doctors trying to treat achillies tendonitis. Nobody helped me with the pain and continuing microtears. Dr. Hyjek worked miracles. I've been pain-free for a couple of years now. He also moved a muscle in my shoulder that slipped and had decreased my range of motion. Again - pain free and full range of motion after 30 seconds of treatment from Dr. Hyjek. I highly recommend him. read more

I started working with Steve due to chronic neck pain, back pain, and extreme limitation in my range of motion in my neck. I pretty much was in pain all the time and had recently taken a job that required me to drive about 20 hours/week. I had worked with a chiropractor many years ago and was unimpressed, however, my wife had been working with Steve for a couple of months with great results. She could not say enough about how positive an experience it was working with him. So given how awful I felt all the time, I figured it could only help. I had been on Humira and was still taking celebrex with very limited benefit and really wanted to get off the medication. My schedule allowed me to work with Steve once a week, but I felt relief from our first session on. I don't know if this is typical or not, but I felt lasting benefit from that very first adjustment. It made me excited to go back. After working with Steve for several months, my back is pain free and I have gained great strides increasing my range of motion in my neck. I have gained an inch in stature and have started reversing an extreme head forward posture. I have been medication free for several months. One of the biggest benefits of working with Steve has been my weight loss and improved overall gut health. In the six months I've worked with Steve I've lost around 30 lbs! I highly recommend Steve for anyone looking to make a positive change in their overall health. I never thought I would feel this good again before I started working with him. read more

What can I say. Dr Steve is an amazing doctor who knows his stuff. He goes out of his way to help make you feel better and get on track. He doesn't try to push meds on you but makes recommendations so you can decide unlike other doctors. He listens and truly cares. I have a ton of autoimmune issues. He helped discover my root cause. Because of him; after 7 years of feeling like crap I feel like I have my life back. I have only been seeing him for 2 years and you know what? I feel fortunate to have found him. His products are good, his advice is sound. If you want to feel better please go see him. He really is fantastic. I wish more doctors would do what he does. read more

Since my childhood I have struggled with lower back pain, something I have just gotten accustomed too. Recently though, I also was experiencing problems in my upper back. I walked in to Dr. Steve's office with pain throughout my entire back. From the very beginning he was very helpful, knowledgeable and friendly. Dr Steve has the commanding demeanor that gives a quiet confidence but also a welcoming presence that makes you feel safe. He started by walking me through what was wrong and not only fixing my current pain but starting the road to long term recovery as well. The first month seeing Doctor Steve was amazing, I was experiencing less pain in not only my upper back but also in my lower back for the first time in 15 years! Dr Steve stands out from other Chiropractors that I have been to because of his knowledge, honest approach and results. I am going to continue to work with Dr Steve and work towards a healthier, happier, pain free life. read more

Dr. Steve is amazing!!! I was recently referred to him from a friend from home in MN where he had a very well established practice. I have had several adjustments from him now and feel very confident in his abilities. I even have him adjust my little 1 year old girl. I normally go to a chiropractor that does the same adjustments to me every time I see him....Not the case with Dr. Steve! He adjusts me differently every time based on my chief complaint. He also has a large bag of tools to assist him....like a low level tissue laser. so cool! That has worked wonders on my husbands sprained ankle! He is a wealth of knowledge as well! He is always telling me about new research that is out. And on top of all that, he is working with my on my weight loss goals....and not just with another silly diet. He is looking at my HORMONE levels! He treats the cause, not the symptoms. He treats everything from cholesterol to depression. Try him out, you won't be disappointed!! read more

I have been coming to Dr. Steve for almost a year now. I have an autoimmune disease called Hashimoto. When your immune system attacks the thyroid. In this case making you hypothyroid. When I was diagnosed I refused to go the typical doctor way and read and research on how to control this disease. I am happy to say I do not take any thyroid pills and it has been through Dr. Steve's guidance that I have been able to improve my test results and my overall life. If you have any autoimmune disease, grave, hashimotos, ms, etc.. Do yourself a favor and research and read more about how you can improve your condition with a change in your lifestyle. I am still in contact with my regular doctor for testing. Depending on the time of the day, you might have a quiet moment with the Dr. or a boom box time. The place have a common area with the tables for adjusting and a room for massage. The location is on the upper floor from a gym. The parking can be difficult if you come when people are coming from the classes, but you can find parking around the corner. This looks like an office area in Irvine Dr. Steve accepts insurance, so if you insurance covers Chiropractic care, you can certainly take advantage of this. For the FSA accounts, sometimes you have to send receipts, but for the most part, the copayment and supplements can be paid with your FSA card I searched for a Functional Medicine doctor in the Irvine area, and that is how I found Dr. Steve. He is knowledgeable and when he does not have the answer the search for it. He is also open to learn. I am so grateful as with his guidance and treatment I was able to take my life back. read more

Dr. Steve has been very helpful with treating my back pain. I went to see him after I woke up with intense back pain last year. He listened to my concerns, performed a thorough check up, and came up with a treatment plan. With the treatments, my back started to get better and the pain started going away. Now my back is in better shape than it was before. I'm more flexible and I can do more things and no more back pain. I'm very grateful for his help. read more

Was seen by Steve Hyjek after spending $350 out of pocket for two consultation visits I was told it would be $3000 for labs and for his services for 6 months and a discount on supplements purchased through him. It did. feel like he actually wanted to help me it felt like a slimy sales car pitch. I literally left in tears I was so frustrated and felt defeated after spending so much time rehashing all my issues and health history. I read reviews online and here on Yelp. Too ba no one is brave enough to call out the disservice this man is doing. read more

Dr. Steve has been my Functional Medicine doctor since April of this year. I came to him because I was a diabetic suffering from peripheral neuropathy. I had also suffered for years with acid reflux, bloating and stomach cramps and a poorly functioning thyroid. Through supplements and dietary counseling I have reversed my diabetes, lost 50 lbs. and am off all medications for diabetes, neuropathy and acid reflux. I feel better than I have in 20 years and have more energy than I have ever had, all thanks to Dr. Steve. I highly recommend this caring, knowledgeable doctor. read more
