- 5 out of 5 stars. “Highly recommend Dr. Zhang!I first saw him for a consultation and was impressed by how easy he was to talk to. He took the time to understand my dental history and walked me through my X-rays, even pointing out things no other dentist had mentioned.My cleaning was incredibly thorough, and Dr. Zhang was very considerate of my sensitive teeth—checking in often to ensure I was comfortable. He never pushed unnecessary treatment and explained each recommendation clearly, laying out the pros, cons, and options based on my needs.After getting home from the cleaning, I had some urgent questions, and he kindly squeezed me in the same day. He examined the area of concern carefully and took the time to talk me through it with patience and professionalism.I left with a much better understanding of my dental health—and the cleanest, whitest teeth I’ve ever had after a cleaning.” — Lydia
