William J Schwartz, MD, is Assistant Professor of Cardiology in the Department of Medicine of the Icahn School of Medicine at Mount Sinai. He is board certified in internal medicine and cardiovascular disease. For more than 35 years, he has been committed to caring for patients with cardiac conditions in Queens and Manhattan. He provides compassionate and customized care to patients inherent in his belief that each patient has a biological, psychological and social aspect to their heart condition. He helps his patients understand their medical conditions so that they can best partner with him in treatment plans. He guides patients through the treatment process with the goal of having patients feeling better and living longer.

Dr. Schwartz received his medical degree from Albert Einstein College of Medicine at Yeshiva University and went on to complete a residency in internal medicine and a fellowship in cardiovascular disease at the Bronx Municipal Hospital Center, Albert Einstein College of Medicine. Subsequently, he completed a fellowship in cardiac catheterization at the New York University Hospital. He wanted to practice medicine as a cardiologist as it allowed him to have long-term relationships with patients and have the opportunity to make an immediate and powerful impact on a patient’s well-being through his ability to improve and save lives.

Dr. Schwartz was an early leader in the community in championing continuity of patient care as a key approach to improving patient quality of care and outcomes. He has been active in community outreach though lectures on heart health as well as through a weekly column in the local newspaper. In his column, he related vignettes from his cardiology practice which engaged the community in cardiovascular health through the power of personal stories. He relishes caring for patients of diverse backgrounds with the philosophy that compassion is a universal language.

For over 20 years, he has mentored high school and college students who have expressed an interest in medicine. He continues to teach residents and fellows and hopes to continue to inspire them to be engaged and caring physicians. He is a member of the American Board of Internal Medicine and the American College of Cardiology.

Highly respected and valued by fellow physicians, Dr. Schwartz has received the distinction of being on Castle Connolly America’s Top Doctors, (2010 – 2015) and Castle Connolly Top Doctor’s New York Metro Area, (2000 – 2008, 2010 – 2015) lists. He was nominated by other physicians because of the exceptional care he gives to his patients. He has also been honored with the Vitals Compassionate Doctor Recognition Award, (2015) and the Vitals Patients Choice Award, (2015) based on reviews by patients. These awards are given to less than 5 percent of doctors nationwide.
