Patient Reviews
Feb 18, 2023
I was referred to Dr Tan to diagnose autoimmune diseases. The wait times are a little long but once you see him he takes all the time you need. I prefer this to a Dr running on time but rushing you. He brings his laptop into the exam room and goes over all results with you and explains on any questions you may have. His office staff are very friendly and will help take care of any billing issues you may have with your labs as well as get you authorizations for treatments if needed. I had a different rheumatologist but thought he was very curt and and I did not like the staff so I switched. I'm very pleased thus far with Dr Tan and his team.
