Dr. Huynh is very patient and thorough. He always takes your issues seriously and explains things very clearly. I once was feeling very frustrated with a specialist I was dealing with for a serious and time-sensitive issue, and he called me after office hours on his personal phone to make sure everything was ok and calm me down. Excellent doctor!

Him and his staff are absolutely terrible at communication and returning phone calls. I will never return to see them and would highly discourage anyone wanting to go there as a new patient.
