Dr. Ashtiani is an exceptional heart doctor with a warm, kind, caring and engaging approach to his patients. I have been working with him for over two years and feel he must be unique in the USA for his skills and kind manner.

Dr Yalvac is one in a million whose education and experience is only exceeded by his sincere devotion to his patient’s care. He takes the time to explain your particular heart condition and then creates a treatment plan that focuses on your unique problem. I highly recommend Dr. Yalvac because he cares and his treatment has saved my life… H. Bent

Dr Yalvac is ALWAYS great to see. He explains everything to me thoroughly so tha I am able to understand. And he has a wonderful Bedside manner that puts me at ease.
His assistant is also wonderful. He listens intently to what the doctor is saying and is thorough about transcribing it.

Dr. Yalvac is terrific! Impressively knowledgeable, he articulately communicated while spending much time delving into all aspects of my situation, adding relative, personal quips. Sincerely interested in me as an individual, he listened and addressed my questions in depth; he analyzed the proposed next steps with rationale and supporting evidence. I am extremely pleased with Dr.Yalvac, his exceptional staff, and the entire process and thank my nephrologist for highly recommending him.
