My Approach to Care

The biggest focus of care to me is getting to know each patient. There are different aspects of everyone’s life that led them to where they are and will lead them to where they’re going in the future.

Working with patients on a day-to-day basis is why I chose to get into medicine. I enjoy helping patients improve their health. Being able to take care of somebody, see them improve and follow-up with them long term is definitely the reason why I chose to be an interventional cardiologist.
