Dr. Mark Lazarev is an exceptional physician. He has always been extremely courteous and open-minded to my input during our interactions. He is extremely knowledgeable in regard to his discipline of medicine. I feel very fortunate to have Dr. Lazarev as my current gastroenterologist. When my initial gastroenterologist retired, I was seeking out a new gastroenterologist and so thankful that Dr. Lazarev took me on as a patient in his practice.
