Jayanta Das, M.D.
Dr. Das has been my cardiologist since moving to Valencia, CA, in 2004. I am a n 80-year old female with long-time hypertension and other cardiac issues. Dr. Das is extremely competent, personable, a good listener, and always aware of all my current health issues. At every visit he takes time to go over my most recent blood tests and the results of recent cardiac and other medical tests as they impact my cardiac health. He always responds to my concerns and questions in teams that I can understand. He has kept my cardiac risk factors in check. I never feel rushed during my visits. In addition, his nurse, Michelle, and the office staff at Cardiovascular Consultants Medical Group (CCMG) are respectful, friendly and efficient. I always leave my visit with Dr. Das satisfied and assured.
