Patient Reviews:

Maria S.

Dr. Tan performed a knee replacement on my father Emilio.  He communicated the procedure to him from start to finish.  Dr. Tan made my father feel at ease with the procedure.  He followed up with my father several times after the surgery. My father was so pleased with his outcome and Dr. Tan that he is getting a knee replacement on his other knee this month.  I would highly recommend Dr. Tan to anyone.
