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.

I have been Dr. Mark Isaeff's patient for about 15 yrs. I started seeing him while he was in private practice. When he decided to join MD VIP, I would not have
moved if I didn't have faith in him. He is a christian and that is very important to me. He is very easy to talk to and I feel that he knows my health situations ex-

from Victor in TX January 19, 2024 for Mark A. Isaeff, MD

I had gone from doctors' groups to doctors' groups most of my life, mostly due to the health insurance limitations I had. Because of a routine colonoscopy, I discovered that I had hypertension. The internal medicine group that I went to at the time assigned me to Dr. Mark Isaeff, who began treating me in general, and specifically, treating my hypertension. That was in 2004. Dr.… See more

To give reference, in 2010 I began working full-time in outpatient pediatrics, a very physically demanding job. In 2011, I developed agonizing stomach pain and other GI issues and rapidly lost weight. The next year my body "broke" again, resulting in excruciating pain in my muscles and joints, fatigue not relieved by rest, and a plethora of other fun symptoms. Various tests came back… See more

from Diann in TX March 11, 2020 for Mark A. Isaeff, MD

Dr. Mark, you truly are an amazing physician and caring human being. Every time I leave your office after my semi annual assessment, I just think to myself--WOW, he just spent two hours with me going over all the tests and explaining in a way a layman, even a lawyer like me, can understand. I am so blessed to have you in my life. Thank you and your awesome staff for keeping me healthy and… See more
