I have been a patient of Dr. Isaac since I was 35 (15+ years). I think he is an excellent cardiologist!! He now sees my sons and my husband as well. Highly intelligent and very knowledgeable. He listens and I think he truly cares about his patients. He explains what my disorders are, what they cause, and how the medicine works to treat them. His practice is very, very busy which can make wait times very long sometimes. For me, the wait is well worth the exceptional patient care he provides.

Brilliant, responsive, inspiring! After reviewing my monitor results, Dr I called late PM. He cleared appts. for next AM, to potentially implant a pacemaker for my low heart rate, multiple missed beats, and a congenital heart murmur. Dr. I. reviewed family health history, my dedicated work-out regimen, and successful results of extensive tests (incl. echo, EKG, and stress test), concluding no pacemaker was warranted! Impressive attention to detail and critical thinking to adjust course!

Office staff is disorganized, dishonest, and can't keep up with payments, fails to schedule test ordered by doctor. Wait time is 2-3 hours in front office, then another 45-60 minutes in waiting, finally when Dr. Isaac sees you, he spares about 5-7 minutes of his time, and leaves you clueless as to how your results turned out.

Dr. Isaac is best cardiologist in Houston Texas plain and simple. Although his wait times can take some patience, I assure you that no one will give you higher quality care and love that Dr. Isaac will provide for you. He takes care of not only me, but my entire family. When choosing a cardiologist, I advise you go with Dr. Isaac.

Dr. Issac is a great cardiologist but his wait time are intolerable. And it seems that they are just getting worse. He is thorough and extremely bright and has a terrific bedside manner. I just wish you didn't have to spend a half day waiting for an appointment. Its discouraging since i don't think there are many who are better!

Wait times are ridiculously long - 2 1/2 to 3 hours. No one, especially my 87 year old mother should have to wait this long. We are changing cardiologists.
