Always enjoy seeing Dr. Cai. Took me a long time to find a Doctor I meshed well with after my last good one retired in 2010. Dr. Cai always listens without judging or getting impatient, never rushed things but is efficient, doesn't waste time, and doesn't leave awkward pauses in conversation.

Dr. Cai has been very helpful and instrumental in helping me work through a very difficult time in my life, constantly making sure I'm healthy while I cared for someone else. Now that this time has passed, he'd still very focused on my health, keeping me going as long as possible.
