Care Philosophy

This content was provided by Dr. Loussararian "One of the most rewarding things about being a cardiologist is that I have the opportunity to make a difference in people's lives.  I get tremendous gratification in seeing patients get through a difficult illness and return to a productive life.  I have patients in my practice who I have followed for 10 or 15 years, and I take pride in the fact that I have partnered with them to achieve their health goals."

Patient Comments (5)

14 years ago he saved my fathers life and extended it by 6 wonderful years. Now he’s done it again by directing my boyfriends care and saving his life. I will be forever grateful to Dr. Lou and his assistant, Billie, who’s is always there to answer my questions and peel me off the ceiling.
