This quiet, intelligent, informed and responsive interventionist cardiologist has been largely responsible for the fact that, after 20 years under his care, I continue to live a normal and enjoyable life in my 95th year. Dr Loussararian is an honor to his profession, and I give him my unqualified recommendation.

I was first treated by Dr. Lou in 2004 when I was able to reach Mission Hospital’s Emergency Room while having a heart attack. There, Dr. Lou quickly and expertly cleared a heart valve blockage, installed a stent and thereby saved my life, extending it, as of this writing, by 14 years. Since then, Dr. Lou has continually improved the quality of my life by very accurately diagnosing and surgically resolving multiple vascular problems. Dr. Lou’s diagnostic and surgical skills are truly impressive.

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.

At first He looks and seems cold and not friendly , BUT you have to get to know him , for 18 years we have been taking our dear father to him and up to the last minute of our fathers life he was by our side in the hospital even when we though Doctors will not come to visit any more since it was just a matter of hours . His diagnoses were always accurate and we had complete trust in him and his decisions. He treated our old father with love and respect !THANK YOU DR.Lou for all you have done!
