Mark Lieb

One of the nicest and best doctors I know. If anyone has an issue with reaching him it is probably due to administrative changes in his staff. Sincerely belief he gives his all day in day out.

This is not the right doctor for anyone who is old. I am shocked by the reviews saying what a great doctor he is. My father received the WORST care from Dr Lieb. He never returned any calls, never called with test results while my parents waited anxiously by the phone hoping everything was okay with my father and the one time he did call he seemed put out that he even had to. Claremont is like the Walmart of medical care. I would not recommend to anyone who cares about their health. This is not the right doctor for anyone who is old.

I chose Dr. Lieb because my Internist and his father uses him. I have had a few different Cardiologists in the Caremount practice, and Dr. Lieb has been the best. I'm 72, and receive excellent treatment for my Cardiomyopathy. He gives me an incredible amount of information about my condition, what the choices or options are, and advice to keep myself as healthy as possible. Dr. Lieb allows me as much time as I need, can ask any questions, and never feel rushed or that he ended the session. The doctor seems genuinely concerned for my wellbeing.

Dr Lieb is a through and totally professional His calm and considered approach in obtaining all facts about my condition ,full analysis of that information and well considered and communicated plan to address my condition is greatly appreciated and comforting. He is a top flight doctor who I would fully recommended to family and friends.

Does not give the same attention to seniors as he does his younger patients. Extremely disappointed in the care my father received. Almost all appointments were with the nurse practitioner. 100% unacceptable.

Worst doctor I have ever met. I took my mother here for a check up. He kept us waiting in the exam room for almost an hour. When he finally showed up, we couldn't understand anything he was saying and left us to go see another patient! He also took a phone call during the examination! Most unprofessional, unqualified, and incompetent doctor. My best advice to stay far away as possible!

Needing an experienced cardiologist, I came upon this doctor during online search. I immediately called and was able to see him about three weeks later. I liked his very professional way of questioning and listening. Very attentive, and concentrated on my elevated blood pressure, telling me that he'd focus on that issue first due to my family history and BP readings. He was generous with his time, giving clear instruction and guidance. I'm grateful to be in his care. Wonderful staff also.
