5 /5 Katalynn Isamelia: Dr. Gu has been my doctor for years and hopefully for many more to come. IDK how he does it, but he takes time to listen to you, he is very thorough, hes kind, and keeps the clinic on a schedule. When I come in for an appointment, Im always seen on time. Hes been such a great doctor for me, my son is now seeing him, too.
