John Macgregor, MD, PhD


Dr. John S. MacGregor is a cardiologist and an interventional cardiologist. He received his medical degree from Cornell University Medical College, where he was in the Medical Scientist Training Program (MSTP). As part of the MSTP he also earned a Ph.D. in biochemistry. After receiving his M.D. and Ph.D. degrees, Dr. MacGregor did research at Rockefeller University, followed by internal medicine training at the University of California San Diego, and finally cardiology and interventional cardiology training at the University of California San Francisco (UCSF).

Since completing his training, Dr. MacGregor has been on the faculty of UCSF where he is currently a Professor of Medicine. Since 1991 he has been the Director of the Cardiac Catheterization Laboratory and Interventional Cardiology at San Francisco General Hospital. His main area of interest is the endovascular treatment of coronary artery disease.
