    Dr. Haas is one of the best doctors I've ever seen! He really listens and doesn't make me feel rushed at all. He also makes sure that both my husband and I understand what he thinks is going on and what his recommendations are. He's extremely personable and I recommend him to anyone who's looking for a cardiologist.

    Dr. Haas is extremely helpful and listens well. He took the time to make sure I was able to describe my health concerns and to understand and participate in the plan to address them. I can wholeheartedly recommend Dr. Haas to anyone who needs cardiac care. I'll have a difficult time recommending the practice due to previously mentioned issues with scheduling appointments.
