Dr Chu was very attentive and listened thoroughly to my concerns. He advised me of what he believed my issues were and also advised me of the process to investigate. He is a keeper! You don't find may physicians (regardless of specialty) that listen to the patient, look the patient in the eye and check into the patient's concerns BEFORE writing a prescription.

Very attentive and thorough. I never felt rushed and felt like Dr. Chu was putting together a very complete picture of what was going on with me. He explained everything that he thought was going on, lifestyle factors, and how we would move forward with testing and treatment. His staff was great and got me appointments that I needed and always called back when they said they would.

I'm so glad I picked him! I laughed & I cried during the appointment and he made me feel great during both instances. I completely trust look into my stomach & diagnose me. I was so relieved when I left. The only thing that he may have lost points for had nothing to do with him. The next day I had to schedule an appt for a test but I never received that phone call. This now overshadows much of his qualities, but I still do trust his knowledge.
