Dr Steiner and his staff and office is fantastic! He takes time to listen to our concerns and is super collaborative in discussing next steps. My husband and I have been seeing him for years and Dr Steiner is the most thoughtful, caring and knowledgeable cardiologist we are so blessed to have in “our corner”! We will not see anyone else!!!

Dr. Steiner saw me on very short notice. He did an outstanding job of responding to my concerns with a careful explanation of why the treatment plan was appropriate for me. And he modified somewhat my medication‘s in response to my concerns and medical condition. I couldn’t have asked for a better meeting.
