Dr. Kersh has given me excellent care for over 20 years. He is a man of great learning, good humor, and decisive action. He involves himself in every aspect of care, checking on test procedures and diagnostics while happening. Really a very good hearted man who has helped me overcome my most serious coronary problems and managing the chronic issues very well. I couldn't ask for a better doctor. His office is easy to get to, close to 24th Street BART. I now come from Oakland so that makes it easier. The staff is superb, attentive, and knowledgeable. Wait times are minimal.
