My Philosophy and Approach to Wellness...

I believe that we all have different gifts and talents. For me, I have been given the gift of teaching and healing. I have an innate sense for identifying problems and illness in people and communicating them in understandable ways. Looking each person in the eye I give you my undivided attention. You are exceedingly valuable and infinite in worth. I will not judge you. As your doctor, I am your friend. And as your friend, I will share my gifts with you. In the end healing is easier when relationships are found.

In 2011, I developed agonizing stomach pain and other GI issues and rapidly lost weight.

Mark Isaeff has made a difference in my life. I'm sure he added at least two years to my wife's life. And he has added to mine. He has helped me overcome pneumonia, lung blood clot, two bowel resections and spinal arthritis and a bulging disc. His prescriptions and supplements keep me able to deal with daily life and keep going at almost 88. He is smart, aggressive and knows the human body. … See more
