Both my husband and I have been patients of Dr. Merson for several years and could not ask for a better PCP. He has everything we look for in a doctor - extremely knowledgeable and up-to-date on a very wide range of medical conditions and issues (he seems to know more about some than specialists we have consulted with), very thorough in his examinations and assessments, and easy to talk to, caring and compassionate. In addition, we never have to wait more than 10 minutes or so before we are seen
