Your trust is our top concern.

We strive to keep the reviews trustworthy, honest & fair.

We monitor all reviews to ensure they comply with our guidelines and don’t include personal information, profanity, libel, defamation, harassment, obscenity or fraud.

All reviews are confirmed and audited before publication, and community members have the ability to flag inappropriate content for further review by our team.

Doctors can not pay for good reviews, nor can they pay to have negative reviews removed.

Any reviews that are deemed fraudulent or violate our guidelines will be removed immediately.

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.

Dr Loussararian did an excellent procedure on both lower legs opening up closed arteries. i came in from nevada where other drs were either unable or too risk adverse to do the surgeries. i was in extreme pain and my legs were very swollen and black and blue from the lack of blood flow. immediately after i was able to walk without pain where i was unable to previous.

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.

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!
