Dr. Markov is an excellent doctor and helped treat my hyperthyroidism and grave disease and got it under control. I really appreciate him. He's very, very nice, approachable, warm. He's very kind, easy to talk to and explains things great. I'm a nurse myself and I really appreciate the level of care he gave me. I think he's phenomenal. I would recommend him to anybody. And he's really, really great and wonderful doctor. So I'm very thankful for him.
