Dr. Isaac is a world-class authority on cardiovascular and cardiology medical science. I found him to be extremely kind, competent and methodical. He's probably one of the top cardiology specialists in Houston if not Texas and the country. His clinic staff are also superbly efficient and courteous.

Dr. Isaac seems like a good doctor but the staff is frustrating. Wouldn’t find answers to my questions. Won’t return calls. They don’t know their contracted rates. One nurse told me one thing and the next nurse told me the opposite. They seem confused about how to do their job. They are used to patients that are hard of hearing and gossip about patients. They seem to have too many patients to adequately care for anyone. I would consider seeing a different doctor at a different office.

All appointments and care is excellent. The only draw back is in trying to contact his staff. Phone answering device is a bit laborious and getting to talk to a real person is difficult. Dr Issac is by far the best Cardioligist I have seen.

Dr. Issac is warm, kind and caring. He's professional and he definitely knows his stuff. I wouldn't want to use any other cardiologist.

Dr. Isaac found what other doctors had not. He was very professional when confronted with this fact. He said nothing bad about the other doctors. He is a very caring individual; a "heart doctor with a heart".

The wait time for a scheduled appointment is poor by any standards. I understand that unexpected things crop up that will delay. However, it would be very easy for the office staff to simply explain the delays so that you can reschedule.
