Hobbies and Inter​ests

When he’s not caring for patients, Dr. Nigam enjoys spending time with his family, cooking and reading.

​I believe in a caring partnership with my patients. We are a team, and together, we can work toward a treatment plan that is beneficial to my patient and their loved ones. I believe good communication goes hand-in-hand with good patient medical care. And under my care, I try to answer their questions and address their concerns.
