Patient Reviews (5)
During the initial exam he never introduced himself and left the door wide open, which was adjacent to his clinic area. Patients could hear and see the entire office visit although there was nothing to see since he did absolutely no physical exam. He did order a lot of lab tests to narrow down the issue but was no more professional on my second and final visit.

Dr. Jason is an extremely experienced Rheumatologist, very good at diagnosis and treatment of arthritis and other auto-immune diseases. His treatment has turned my severe arthritis problems into manageable issues for me, without him I'd be in a wheelchair. Highly recommended. He has a great staff and facilities too.
Dr Jason came In the room after I had waited patiently for 40 min. He said why can't you understand I was taking a dance class and he was trying to get tickets to JLo in Vegas. I am a sick patient who is PAYING to hear this? After that he told me I should stop complaining about my pain & watch him do the moon walk! I almost burst into tears. He has no regard for sick patients and I think he should be checked in the head.

Wow switched doctors and the better RA doctor couldn't believe the mg of predazon which may cause severe long term effects. This guy only plays piano and doesn't even talk to patients. I tell you he overmedicated my husband for three years and wow really the better RA doctor couldn't believe the amount of mg of predazone and said in his 30 years he's NEVER prescribed that much dosage. Stay away.

I was delivered the horrible news that I had HLA-B27 and was sitting in a gown with my butt hanging out, pondering if I should have children. I was left there by myself, when he came in the room and started laughing and taking calls for tickets for the Phantom of the Opera. He explained to me it was for charity. Nice, but not professional or considerate. I never went back.
