I feel so blessed and thankful to have him in our lives. There are no more doctors like him. I see why people come from all over the world to see him, very thankful.

Dr. Winkler is a treasure trove of information, and experience. I’ve been to many integrative medicine doctors and his approach was unique, refreshing, and more importantly… I saw immediate results. Highly recommended

Dr. Winkler is very well educated and can apply his medical and holistic knowledge for each individual. He is caring & generous. He and his staff go above and beyond to address your individual health issues. Dr. Winkler is genuinely concerned for his patients. The staff is very friendly and they make you feel comfortable.

Dr. Winkler was my doctor for a number of years. It has taken time to write a review as I experienced a sudden and painful lack of trust. Dr. Winkler was knowledgeable on many things, but over time he seemed to be very unhappy when I would not buy Supplements from him, which are very expensive and I was on a limited income, and so I bought the exact same supplements much cheaper elsewhere online. He tried to tell me they could only be sold by doctors but they were not prescription medications. After a while and much stress during active mission work over seas it became apparent I had adrenal fatigue issues, I trusted him too much. I then moved to Texas to get married and Dr. Winkler believed my husband was a wealthy oil man, I flew out to see him for help with returning adrenal fatigue symptoms that were severe. During our conference he had an assistant talk to me about how much money my husband made and insisted I must delay my trip home, get 3-4 days of testing done for what he called “paradoxical” reactions to treatment and repeatedly asked me how much money I had. I had a friend with me and she was furious when she heard he was so “greedy”. I had been made to feel I would die if he did not get the money he asked for and that I must subject myself to many inexplicable tests. I left his office determined never to return. God helped me find a much better treatment with a specialist in adrenal fatigue, who gives coaching for $25 on the phone. It’s Dr. Lam. If you have Adrenal fatigue go to Dr. Lam. He’s online too. Dr Winkler does not understand adrenal fatigue and he can see you as a pot of gold if he thinks he can do enough experimenting on you. Very draconian! My one star rating is the result of being disappointed in a doctor I loved and trusted. I felt very sad I could never trust him again. ET

I am appreciative of Dr. Winklers support and provision of health care. Dr. Winkler and his staff have been wonderfully kind and professional!

Love this place, staff and Dr Winkler!

Dr. Winkler is a Functional MD-Naturopath, and thank goodness for him and his team of wonderful, caring and efficient professionals. He addresses the underlying imbalances at the organ and whole-body systemic levels of biochemical cascades and interactions; while also prescribing pharmaceuticals as necessary.I have always found his interventions and recommendations published on PubMed/NIH, in Clinical Journal research articles. This is a small office operation, without the systems of software and personnel such as Kaiser and Scripps. Ive found this best addressed by taking as much charge as possible re: follow up, asking questions and communication.Dr. Winkler and his Quantum Functional Medicine staff are full of humor, warmth, and practical approaches which are refreshing and effective. Our family is blessed to have found him and the entire QFMed team!

Dr. WInkler is one of the few who is both an MD and a Naturapath. He has helped me greatly with my Thyroid- an area that my regular MD will not look at. He caught my pre-diabetes condition before my regular doctor did. He got me to see a nutritionist to figure out my weight issues that my regular doctor could not figure out. Cant say enough ! He is very thorough and Analytical and compationate about helping people.
