Your trust is our top concern.

We strive to keep reviews honest, trustworthy, and fair.

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

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

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

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

Completely blown away by this Dr!
I'm a daughter of an internist and not since my father have I met and known anyone as thorough and caring as Dr. Tabassomi. During my 1st visit I couldn't recall my last hospital visit. He not only looked up everything, but knew about all the testing results BEFORE he even stepped into the exam room to see me. SO IMPRESSED. He's kind, patient, and no bull. I highly recommend him. ALSO - his office staff is EXCELLENT - no rude, cold robots at his office.

First off, I will say that 2 reviewers have put on their review that Dr. Tabassomi is "The best pulmonologist in Valencia." I disgaree, Dr. Tabassomi is the best pulmonologist in Los Angeles County! Period. I am incredibly impressed by his level of patience, ability to completely answer my question / questions and overall balance of knowledge in his specialized area of medicine. He sets himself apart from the rest (physicians in general, and also, their "bedside manner"). In addition, his entire office staff is also fantastic including Alex and the individuals that conduct his PFT's (Pulmonary Function Tests) Emin and Minely. 5 Stars!

Dr. Tabassomi is extremely knowlegable and professional in his field. When I got sick with pnemonia, he treated me with both antibiotic and antifungus medications while in the hospital. Later I find out I had valley fever, if it wasn't for his right diagnosis it would have been pretty bad situation. He is so friendly and caring. Thank you Dr. Tabassomi for saving my life.

Dr. Tabassomi is a miracle worker and absolutely the best in his field. I did a lot of research to find a good doctor for lung cancer treatment and got referred to him through several sources. He is truly great, very knowledgeable, confident and caring. He knows exactly what he is doing and I could trust him with all the decisions, such a relief. He saved my life and gave me the gift of breathing again.
