Headshot of Roy G. Marcus, MD

I believe that quality medical care must the based on the best medical evidence available yet at the same time be individualized for the specific features of each patient. Patient education is critical as patients need to understand how they can adapt their lifestyle to positively impact their medical condition. I believe that developing strategies to prevent future medical problems is key to optimize my patient's health. I also strive to treat each individual with the same dignity and respect as I would treat my own family.
