Initial visit. Knowledgeable and patient.

Very friendly and professional. I had questions regarding financial responsibility and they answered my questions, letting me know they were glad I asked and happy to answer.

September 2026 

My appointment was at 3, and I was taken to a room at 2:59! The doctor came into the patient room very quickly. We discussed my issues since my last visit, and went over plans for helping with my issues. Dr. Nam is very conscientious and thorough. Plans were also made for me to call within a week to let Dr. know how medication was doing.
