Dr. Tan diagnosed Rheumatoid arthritis when I don't have it. Thankfully I got a 2nd opinion and more blood work. He is just interested in giving meds and having patients come back to him.

I have nothing but wonderful things to say about Dr. Tan. From the first visit he made me feel so comfortable, it was like talking with an old friend. He is super intelligent and compassionate. In a nutshell...he knows his business!! Though I must admit, sometimes the wait time is longer than I would like, but it really is worth it!
