As a 26 year old battling an aggressive form of cancer. With no explanation as to "why" I have looked at everything possible to help me fight and beat this. I have done chemo, radiation, everything under the sun. About 6 months ago, I came across Dr. Stenglers office a more alternative/holistic side of healing. I can't say enough good things about Dr. Stengler's office. From the moment you walk in, you're greeted by an amazing staff who truly make you feel welcome and cared for. The facility is always spotless, which makes a big difference when you're spending time there. The team is incredibly knowledgeable--honestly beyond belief--and they take the time to explain things in a way that makes you feel confident and informed. Appointments are always timely, and you never feel rushed. What stands out the most is how much they genuinely care about their patients. You're not just another appointment on the schedule, they really take the time to check in and support you. The infusion room is another highlight: it's calm, quiet, and has such a friendly atmosphere that makes the experience so much more comfortable. The nurse Greta, is beyond sweet and really takes time to make you feel welcomed. I meet with Dr. Stengler and Dr. LaBeau often and I truly look forward to the days I get to go. Which says a lot, considering the last place I want to be is at another appointment. I highly recommend. I wish I would've came here when I was first diagnosed. I have told everyone I know about this team and I pray they listen and go check them out. There is so much information out there, the staff here will help you with a treatment tailored to YOU, YOUR body and YOUR healing. read more

I have been seeing Dr. Stengler since late 2021. I have been regularly taking the Stengler Supreme Multi and Collagen supplements over the last several years. I also recently started taking the Thyroid Wellness and the Vitamin D3+K2, based on analysis of my blood work by Dr. Stengler. My most recent blood work, after having taken the newest supplements for about two months, showed an improvement for my hormone, thyroid and Vitamin D markers. I will be retesting again in six months, to verify that each of these markers continue to improve with the daily supplements. Dr. Stengler is also working with me on gut health and diet, so looking forward to continued improvement there also. I highly recommend Dr. Stengler for Integrative Medicine and the Stengler supplements for overall health improvement. read more

I have been using NAC for a couple of months now and it's helped me with my allergies so much! My allergies are extremely bad and being pregnant I cannot do much to combat them.

I let her know I haven't been able to sleep in 4 days because of my allergies and the day I took them I was able to sleep like a baby! HIGHLY HIGHLY recommend read more

I doubt I will ever be able to adequately describe the gratitude I feel or the confidence I feel knowing I have a doctor to genuinely cares and she shows it. Dr. Angela Stengler is in a league of her own and one of the best physicians I have been blessed to have. Reality is I know I am not the only one. Her approach is that of PREVENTION! I couldn't recommend her enough and so so grateful she is my doctor. read more

I finally found Dr. Stengler March of 2026 and I am so grateful that I did. I have been struggling with some very difficult symptoms of IBS and had tried many different medications that caused unwanted side effects. His first suggestion of Pharma GABA by Natural Factors helped almost immediately for nausea. He has listened very carefully and answered all of my questions very thoughtfully. He has given me a number of options and ideas and gives me great guidance on introducing anything very gradually, due to my sensitive intestines. I am definitely making progress with these natural alternatives, and feel better than I have felt in a year. Whenever I have questions that I submit through the portal, Dr. Stengler answers almost immediately! That is so unusual and appreciated! Dr. Stengler is extremely knowledgeable and I feel very fortunate to have found him. The front office has always been extremely helpful and kind as well. I am very grateful to have found Dr. Stengler and recommend very highly. read more

My elderly mom has had extensive memory issues in the past. This has been off and on. She recently started taking the Mushroom Memory & Focus Wellness supplement and we both have noticed a significannt improvement in her memory within the first month. I have also noticed a significant improvement with respect to less trips to the bathroom in the middle of the night after taking Prostate Wellness. This has taken a few months and the results have been gradual, but significantly noticeable. read more

They charge an exorbitant amount for a few appointments, schedule tests, sell you supplements made by them, and fail to provide a comprehensive picture of health or solutions that manage what the tests at their most basic level suggest. If they don't sell the supplement, good luck getting a solution from them. Can't get an Rx or an over the counter recommendation unless they sell the solution themselves. The front desk is very rude. You will have to wait in the phone for 15 minutes and then they tell you they will call you back. Expect to get no solution from phone tag for 2 weeks+. read more

Dr. Stengler is an excellent doctor. He really takes the time to listen, which I greatly appreciate. He is very knowledgeable, thoughtful, and clearly very smart. His natural approach to health and wellness is such a breath of fresh air! He will help you take good care of yourself. I feel confident in his guidance. Highly recommend. read more

I first came to this office at the end of 2020, during one of the most difficult times in my life both physically and mentally. Meeting Dr. Angela truly felt like a Godsend. From the very beginning, she took the time to really get to know me, asking thoughtful questions and paying attention to every detail so she could fully understand the bigger picture and get to the root of what was going on. Her kindness, patience, and ability to truly listen have made all the difference in my journey. Every visit, I feel heard and cared for, and I'm continually impressed by her wide-ranging knowledge and dedication. Nearly five years later, I'm still coming here and have learned so much and feel like a new person. I'm so thankful to be under her care. The ladies at the front desk are just as amazing they're always warm, helpful, and somehow always manage to make me smile and laugh when I'm there. They make the office feel welcoming and familiar, like a little community you're happy to be part of. So grateful for this team and all they've done for me!! read more

I ordered three containers of the GUT Wellness Powder after I watched the video. The first time I added the powder to water and next time to Almond Milk. The taste is terrible. Then I called and was told I could put it in any beverage. It doesn't dissolve easily. I travel a lot, and there's no way I could make this product work on the road. When I called to return the three jars, I was told I could only return the unopened ones. This is a rip off. Do not get taken in. There are other products out there that let you return everything. read more

I am so grateful for Dr. Stengler, who has guided me through nearly 15 years of various health challenges. His care is top-notch, his knowledge is exceptional, and above all, he's a man of integrity. + read more

I've followed Dr. Stengler's recommended protocol very diligently for over a year now since my cancer diagnosis which included Vit C IV and his own formulated natural supplements. He monitors and adjusts it accordingly. He is is professional and very knowledgeable and always on top of his research for the latest in natural modalities. His protocol greatly supported and strengthened my immune system and overall wellbeing, made a big difference in feeling a lot better and confident on my body's healing journey. With the numerous books he has authored, he educates his patients to empower themselves, I've learned a lot from them. His nurses and staff are also very helpful and compassionate, making one feel comfortable through the procedures and consultations. I am very grateful to be under his care. Thank you Dr. Stengler! read more

I highly Recommed Dr Stengler, and always have had a wonderful experience with the staff in the 9+ years of being a patient here. He has truly helped me stay in the very best of health. Not only do I look and feel much younger than my biological age, I have the peace of mind knowing everything in my body is working at optimal levels. Catching things before they become an issue is key and that's why regular testing, as well as good diet, exercise, and supplements can make a huge difference. Preventive medicine is the Best Medicine, in my humble opinion. Being able to catch things before they become an issue is ideal and Dr Stengler is like a health detective in that regard. He is able to look at your symptoms, lifestyle, supplements or lack thereof, and test results to determine what needs to be done to invoke positive change. read more

Dr. Stengler and his staff are very professional and caring. Dr. Stengler is very knowledgeable, explains the treatment/ condition and is very thorough. He does not rush you during the appointments and listens patiently. He is very compassionate. One nice thing is that now that I'm an established patient, Dr. Stengler doesn't always need to see me for a visit every time I need a medication dosage adjustment or a referral to a specialist. I just contact the doctor through an online message portal and let him know what's going on, and if he needs to see me, he'll let me know. Otherwise, he's happy to make a referral or change a medication or a dosage or whatever without having to see me. My health has dramatically improved since I have started seeing Dr. Stengler! I highly recommend Dr. Stengler and his clinic! read more

Dr. Stengler has truly been a lifesaver on my long journey to healing. After struggling with long COVID, mold exposure, chronic illness, and heavy metal toxicity, I felt like I had hit a wall with traditional medicine. My body is extremely sensitive, and many treatments that were supposed to help only made me feel worse. But Dr. Stengler approached everything with such care, thoughtfulness, and deep knowledge of integrative medicine. What sets him apart is how carefully he tailors protocols to the individual. He listened to my sensitivities and my symptoms. Not only has he helped me tremendously, but my husband is also a patient and has experienced amazing results. Our two daughters have seen his wife, Angela Stengler, and we've been equally impressed with her care and approach. It's rare to find a practice where the whole family can be supported at such a high level. We're incredibly grateful to have found the Stengler's. If you're dealing with complex, chronic issues or simply want a deeper, more personalized approach to health, Dr. Stengler is the real deal. read more

Stengler center is the best of the best. If you are looking for the most knowledgeable doctor & highest quality of care, visit Dr. Mark Stengler. I drive there from over 2 hours away & it is worth the drive every time! Dr. Angela Stengler is also incredible for women's health if you prefer a women's health practitioner. All of their staff is incredible & accommodating to your needs. If you are struggling with a chronic pain condition, an undiagnosed issue, or just overall wellness, visit Dr. Stengler. Could not recommend Stengler Center for Integrative Medicine enough! read more

My husband and I have been patients of Dr Mark Stengler's since May of 2023. We initially went there as my husband's doctor wanted to start him on metformin for type II pre-diabetes. He ordered labs for both of us and recommended supplements and we are doing great. My husband is 78 years old and not taking any medications. His pre diabetes has been controlled with natural supplements and he is better than ever. We love how he explains our labs and gives us nutritional advice. He is very knowledgeable and up on the latest treatments and supplements. We are very thankful for Dr. Stengler and his office staff who are also all very kind and helpful. If you really want to get to know your body and how to take care of it we highly recommend Dr; Stengler and his staff. read more

Wonderful practice! I was suffering from gut issues and now my issues are being treated and healed. Dr Angela Stengler is wonderful and very knowledgeable!! The office staff is wonderful and the all the supplements in office work wonders!! read more

I Was Very Disillusioned with The Medical Providers in My Area. I Talked with My Trusted Pharmacist, and Asked Him Who He Would Recommend. He Immediately Handed Me a Business Card: "Stengler Center For Integrative Medicine" That Was 5 Years Ago, and I Have Never Been Happier With a Healthcare Provider.. Dr. Stengler is Very Knowledgeable, and I Never Have a Doubt That What He Recommends Is The Best Course Of Treatment. He Really Listens, Takes Great Notes, and His Diagnosis is Spot On. He's Very Friendly and Personable, Something That's Usually Absent in Todays Medical Community. His Associate, Dr. Lebeau is Also a Wonderful Doctor, and Takes His Time with you as Well. Neither Doctor Ever Makes You Feel Rushed, or That They are in a Hurry For You to Leave. The Office Staff is also Very Friendly and Very Efficient. They Take Care of Sending Out Labs and Scripts Almost Immediately. I Can't Say Enough Good Things About the Entire Staff of The Stengler Center.... I Absolutely Recommend...100 Stars! read more

Listened to me and the health issues I have been facing. Genuinely wanting to help me is not common these days especially with western medicine so I'm glad I took this route. Highly recommend read more

I went to Dr. Stengler because i had a very bad gut infection.i was very sick from it.i took in all the labs and GI mapping results which confirmed i had 2 different kinds f bactria in my gut as well as H Pylori. Dr. Stengler reviewed all my labs and test results and told me go to ER and have them perform a CAT scan of my gut. No medication No supplements and charged me $500.00. My advice if you are really sick avoid his medical advise or lack of. There are many good Naturapaths in San Diego County. Dr. Stengler is not on that list. read more

Dr. Mark Stengler is the only doctor we go to now to keep our bodies healthy and in balance. My husband and I get our blood tested every 6-12 months and supplement with anything that is out of balance. Stress, travel, hormones, aging, etc. all work to constantly dip into the reserves in our body, so he makes sure we are optimally healthy. We appreciate how he spends a lot of time with us, each visit. I always enjoyed seeing Dr. Stengler in person because he is such a wealth of knowledge and such a great guy. Now that we've moved out of state, I am grateful that we can still meet with him remotely. read more

Dr Stengler and his staff are always looking out for my best health interests. His office functions effectively to provide the best health care for his patients. I would highly recommend Dr Stengler for anyone looking for a good quality of life. read more

I am so grateful for the Stengler Center and in particular, Dr. Angela! I had been seeing my regular GP for six months with continued 'dismissed and unresolved' health issues before coming to Dr. A. Within a matter of weeks, not only did Dr. A resolve two of my three health issues, but she had recommended a specific imaging test whose results prompted my HMO to order more advanced imaging tests which uncovered the 'mystery un-diagnosis'! They are now working with me towards further resolution. Thank you so much Dr. Angela! I am forever grateful! read more

Dr.Angela was super helpful during my consultation. She was detailed with questions and really helped me realize I had some underlining medical issues I'd need to consider for future visits. Her office staff is also helpful and friendly. I was very happy with my visit read more

Dear Dr. Finally found formula for my stomach by combining your Gut Wellness Powder with apple cider vinegar twice a day and you effectively more than double the price on it? Wow. And I found this out by falling for your misleading ad to buy 3 containers for about $120 after shipping, only to find when I get them that they are half the size of the old containers. Shame on your greedy self! John Kraul Customer since 2020 but maybe not much longer. read more

Dr. Stengler has been working with me to solve gut issues as well as low energy. He sat down with me for an hour during the first visit to go over every area of my health. It was the most thorough intake of health history, setting the tone for the quality of care he provides to his patients. He ordered some extensive lab work and then at my second visit, he went over all the labs in detail, providing a plan of action to help me resolve the issues I have been having for a long time. If you want someone who takes the time to listen to your concerns and explain the why behind the treatment plan or testing, you should give this office a try. It's worth paying out of pocket. read more
