One of the most informative and hollistic providers I’ve had in a while.

I had a wonderful experience at this clinic with Haiqin Deng, NP. She is extremely professional, knowledgeable, and most importantly—she truly listens. In today’s healthcare environment, it can be hard to find a provider who takes the time to hear every concern and address details thoughtfully, but NP Deng did exactly that.
