He is quick, but listens when I talk. Appropriate and personable.

I have nothing but great things to say about Dr. Tan! Especially in this chaotic world we live in with all the demands, rules, and numerous changes in healthcare. Through all that this physician made me feel heard, understood, and most of all he made me feel like I was a person and not just another body on his schedule for the day!
