Philosophy of Care

Deliver patient-centered, evidence-based, quality cardiovascular care through a compassionate and open patient-physician relationship. My hope is for each patient to receive personalized care for their given lifestyle, quality of life, and overall goals. Not all patients fit the mold of clinical trials and no single patient nor their families want to be treated as such. Each patient presents with a problem that is unique to them and while there may be many different ways to treat a particular problem, my job is to the find the solution that best fits the patients needs in efforts to improve quality of life and their overall lifespan.

Clinical Interests

Dr. Singh is a board certified cardiologist and interventional cardiologist who received his medical degree from New York Medical College with induction to the Alpha Omega Alpha Society on graduation. He completed both internship and residency at Stanford University. He completed his cardiology, interventional cardiology, and vascular medicine/intervention training at UCDMC where he received Clinical Fellow of the Year Award and Trainee Research Award with the Department of Internal Medicine. His main clinical interests include high-risk complex percutaneous coronary interventions and complex structural heart interventions.

His clinical interests are the development, practice, and research of a range of minimally invasive procedures for the treatment of complex coronary, structural, and vascular diseases. His other major interest is in educating and mentoring the doctors of tomorrow by working with medical students, residents, and fellows on the inpatient and outpatient cardiology services, and creation and development of research projects to help foster life-long learning and evidence based medical practice.

Research/Academic Interests

Dr. Singh is an investigator on multiple research protocols directed at the treatment of heart disease. He is Director of the Clinical Cardiovascular Research Unit at UC Davis and has co-authored several published articles relating to his research interests.
