I do not think this individual is capable of existing in polite society. He is an abuser of the elderly and has dangerous ideas about health and well being. I cannot stress enough, this man is not sane.

Ever since I met Dr Mark about 10 yrs ago he’s always been persistant about solving whatever ailment I have. He always gives me hope about the auto immune diseases I have. He truly cares about your mental and physical health. I will always be appreciative of his spiritual side as it has helped me in many ways. As you can see I am proud to have known him and hope he can continue giving me hope.

He takes time to fully explain results of the large, complete blood panel testing and what I need to do to improve the numbers. He answers my questions in great detail. By following his recommended diet, I brought my sugar level back to normal and additionally lost 10 pounds. I highly recommend him!

Dr. Mark Isaeff has been my internist for a number of years. I love his caring ways and his cheerfulness at night even when I call and need medical advice because of an emergency. I have been pleased with his medical advice and recommend others have him as their internist.

I am a young, single professional woman within healthcare and never thought I'd ever be "me" again. After cancer and subsequent serious complications from the chemo, I was shuttled from specialist to specialist with dozens of diagnoses and prescribed an inordinate amount of prescriptions--including narcotics. I finally realized that my primary care doctor was not overseeing my care and being my advocate. Several doctor friends implored me to see a new doctor and dropped his name as an excellent internist. Upon thorough examination, immediately caught something that no one else did and acted aggressively but compassionately. Now, within 2 months, this man has done more for me than 8 specialists did in 18 months. I refer to him as my hero!!!
