I’m a functional and regenerative patient of Dr Mark’s and highly recommend Dr Mark and his interactive "How to Optimize Your Immune Health" Course. Prior to the course, I accumulated many health issues over the years and despite paying special attention to my diet and lifestyle, my health continued to deteriorate. I have seen many different doctors over the years yet never able to find anyone who could diagnosed me properly and provide any resolution to my health problems until I found Dr. Mark. After seeing Dr. Mark, and taking his online courses, I have learnt that many seemingly unrelated problems are intertwined with each other and many of these root causes were responsible for my chronic health problems. After taking this course, I learned to fully manage my health and now my years of poor immunity, chronic fatigue, insomnia, stress, imbalances, mood swings, and a host of other health problems have dissipated. Dr. Mark is an excellent instructor and a caring physician. I really appreciate the breadth and depth of knowledge covered in this immunity course as well as the guidance and compassion I received from Dr. Mark and his staff. I am very grateful to Dr. Mark for my health and wellness and feel very fortunate to have taken his course.

I highly recommend Dr. Mark's "How to Optimize Your Immune Health" Course. I really enjoy this interactive course and feel very fortunate to take it. Before I took this course, I have had years of fatigue, discomfort over my body, poor sleeping quality, mood swings, and a lot of other problems such as easy to catch a cold. Over the years, I accumulated a lot of stress although I lived very carefully. I watched my diet carefully and maintained a very careful lifestyle. I was in different clinician's offices for years. And yet my problems were never solved, and my symptoms were hardly improved. After taking this course, I started to learn that surprisingly these seemingly unrelated problems are intertwined with each other and share the same root-cause. Dr. Mark has laid out a good foundation in this course and explained well to us why our immune system got weakened and problems start to occur. After I followed the instructions from this course and took action, it is amazing to experience the changes in my body. I no longer have my daily fatigue. During the day I am filled with energy! I have much better sleeping quality and wake up in the morning full of freshness and energy! It has been months that I have not got sick or caught a cold, which usually was a problem for me in the past. There are a lot more incredible changes, which I can make a long list of. I feel confident again. I really appreciate the breadth and depth of knowledge covered in this course as well as the guidance and compassion I received from this course. I am very grateful to Dr. Mark for my health and wellness. - rated on 09/08/20

I was given an ap;pointment for esophagal dilationby Dr. Mark. He did an excellent job, explained what I might exp;ect, and followed up in writing before I even the surgical center. Coordination with his support staff was excellent: my anesthetic was proper to my case, nurses assigned to my case were were knowledgeable and prepared. In short, Dr. Mark provided a stress-free procedure performed by cheerful experienced people. I am very satisfied.
