I have been seeing Dr. Stengler for many years for different health issues. I also see an Internist and find having different views and treatments has kept me healthy. I am 73 and still going strong. He has written many books about natural healing which are very helpful. You really cannot find a better Natural Doctor!!

Even with his heavy patient load and research endeavors, during my twice-annual visits with him I always get the sense that he knows and remembers me as an individual patient, as opposed to one in a line of many, and I appreciate his care, insight, and guidance towards my ongoing, overall health.

Dr. Stengler actually cares about people. He's responsive - even though I'm generally all over the place with anxiety about my symptoms. He's validating, helpful, and is an expert in his field. I'm grateful to have found another human who's genuinely kind and seeks to heal without any hidden agendas. His staff whom I've spoken to on the phone is also very helpful, kind, and compassionate. Highly recommend.

Aside from my hypothyroid symptoms disappearing, my blood work/labs being greatly improved and receiving holistic care-Dr. Stengler and his wonderful staff have provided me with top notch care and services while also providing a warm, welcoming atmosphere. I look forward to my visits-the staff is amazing and I always learn something new. I can’t thank Dr. Stengler and his staff enough.

I was experiencing bouts of fatigue that lasted from a day or two, up to weeks at a time. I went to a number of doctors who
– after doing lots of tests – told me there was nothing wrong with me. But still, I had bouts of fatigue that threatened to leave me jobless. A friend of mine told me to look for a naturopathic doctor, and I found Dr. Stengler. After telling him my symptoms, he told me I had Chronic Fatigue Syndrome. His treatments got me back to work back to normal energy levels.

Dr. Stengler had been my Doctor for over 10 years! Not only is he an expert in natural medicine, he really does care about making you well. One thing I love about Dr. Stengler is that he is always up on the latest science and is very innovative in his approach to making you well. His staff is warm and caring as well. Highly Proffessional.

5 years and feeling better than ever! So grateful to Dr Stengler and his wonderful staff for their wholistic approach to health and nutrition. I am healthier than ever and feel better than ever...definitely much younger than my years! Please see my previous reviews for more details, and here's a funny story...A client of mine who lives in another state mentioned she has been going to a naturopathic Dr in Encinitas and we smiled when we realized we both go to Dr Stengler. I also just purchased his recent book "Outside the Box Cancer Therapies" for a relative who has gone through 2 years of chemo and is clear for now. It's got a lot of preventative as well as helpful therapies for those going through cancer treatments.

I've been going through chemotherapy for almost a year now and due to its side effects, no other doctor has been able to figure out the issue until I met Dr. Stengler! He not only reviewed all the blood work I brought him, he also suggested other tests that regular doctors do not use. I have now switched my primary care doctor over to Dr. Stengler because I trust integrative medicine more than anything! Thank you!!

I am a virtual, out of state client but have had such a great experience so far. Each test he ran was spot on and really helped identify the ROOT cause of my issues: mold exposure. So happy to have answers and to be feeling better on my protocol.

Have been going to Dr. Stengler for the past 15 years for all my medical needs. Excellent doctor, but he will not give you a pill and send you out of the door. You have to follow his advice and do the work yourself. If you value your health go to Dr. Stengler.

I started seeing Dr. Stengler almost 3 years ago, following the recommendation of a good friend, hoping he could address and alleviate the hot flashes I was experiencing due to hormonal changes. From my first visit I could tell that Dr. Stengler truly cared about me and wanted to help, and within a few weeks of that first visit my hot flashes were a thing of the past! I love that Dr. Stengler treats his patients holistically, focusing on overall health, and using natural remedies and lifestyle changes to address areas of concern. I know that Dr. Stengler has many patients and invests a good portion of each day researching the latest industry data, to ensure he continues providing optimal care to all of his patients. Even with his heavy patient load and research endeavors, during my twice-annual visits with him I always get the sense that he knows and remembers me as an individual patient, as opposed to one in a line of many, and I appreciate his care, insight, and guidance towards my ongoing, overall health.

I have been seeing dr Stengler for help with Hashimotos for about six or seven years. I travel from San Jose to see him, or we have phone appointments. He helped me so much when no other doctor in my area could. I saw at least eight doctors here, conventional and functional or naturopathic, and nobody helped. As soon as Dr Stengler put me on the right medications and supplements, I was finally able to function and not sit on my couch crying like I had been. He helps me with other issues too not just the Hashimotos. He's so caring and good at what he does. I highly recommend him.

Absolutely love this dr office! Great attention was given when discussing my medical situation. Ongoing care has been wonderful and I continue to see the fruit of the medical advice given. The messaging app "customer portal" makes communication with the Drs fast and convenient and when I don't have time to get into the office for an in person visit they will do telemedicine depending on the situation. Highly recommend these drs to all my friends and family.

Dr stengler is patient, kind, and attentive. It is worth the cash pay prices to see him for his services. He has helped me immensely in treating my thyroid issues and his staff and office is wonderful. Highly recommend for people serious about getting healthy or optimal.

There are certain times and people in your life that require a shout out, especially if it can help others. For the past 8 years I have been under the care of Dr Mark Stengler. What initially sent me to him was a stage 3 cancer diagnosis, with an outcome everyone prays for....clear for 8 years. Dr Stengler, now being my primary doctor, provides a level of care I have never experienced. He continuously follows up with extensive and thorough lab reports to monitor any potential areas of concern, which brings me to why I post today. I had my appointment today to review my most recent labs and fortunately we had little to talk about. Understanding the imperfect person that I am, it is because of his continual monitoring and regimented supplement protocol that has delivered me the peace of mind I wish for everyone. You WILL NOT find a more knowledgeable, caring and compassionate doctor.

Think all berberine supplements are created equal? Think again. While berberine is clinically proven to support healthy blood sugar and cholesterol levels, most forms have terrible absorption—less than 1%!
