it was difficult for her to explain the purpose of skin grafting and adding gum to lower front teeth, while telling me best option was to get bracket to hold teeth in place but I could also get gum treatment however I had little room to apply the gums to lower area and then gave me an estimate for the cost of doing so! Utterly confusing!

I highly recommend Dr.Zhang for any periodontal and extraction procedures. I trust in her work, and have had my family see her for their procedures.Given she specializes in gums and bone health, she is my go to Periodontist for extractions and cleanings.She is very competent and thorough with my extraction procedure.She is the "extraction queen" my procedure was quick and painless. I wasn't in any pain the next day. I also healed incredibly fast. Thanks to Dr.Zhang, for putting in the work of extracting my teeth and giving my sockets a thorough cleaning to promote proper healing.Plus she offers a few sedation options. The non-IV pill and nitrous worked amazingly on me.Dr.Zhang also followed up with me the next day after surgery. That was very thoughtful of her to check up on me.

Doctor seemed frustrated about my questions over treatment plan. This is an important decision to make, and I wanted to thoroughly understand my options. I'm not a medical person. I needed further explanation. Doctor was not sympathetic.

Dr. Zhang was VERY thorough in going through my prognosis and what the plan is going to be moving forward. She took the time to answer what few questions that I had and even addressed a couple of things that I hadn't gotten around to asking before I could get the chance. Between her and the nurse, I felt VERY well informed.

Dr. Zhang was very caring and seemed concerned that she do exactly what was the best treatment for me, which turned out to be draining an abscess. Dr. Zhang asked many times if I was ok or uncomfortable in any way.

My hygienest was excellent in the time and care that she took on my teeth. I only got to speak with Dr. Zhang between two of her patients, so I wasn't able to get the complete exam that I needed from her to proceed with my tooth implant.

I appreciated the thoroughness of Dr Zhang's dental exam, her professionalism, and clear explanations. She is one of the best dentists (only periodontist) I have seen in quite some time. She took a good amount of time to explain the treatment options, and why some were or were not applicable. I also really appreciated this because I came specifically to hear her expert opinion. She was professional, and spoke at good level for a non-medical patient.

The doctor is good. Seemed a bit angry, scolding me the first couple times I saw her (I've been coming to your clinic for 5 years). She would talk so fast like she was hurrying to another appointment. The last time she saw me, she was very much changed, took more time, seemed to be on my side and quite kind.

It felt like the doctor was rushed. I would have preferred a sit down across a table to discuss more at length options for treatments, prognoses of those options, etc. I didn't feel like I had adequate time to ask all my questions. I hope to be able to have more questions answered when I am there next time

Going to the dentist/periodontist office is very stressful for me. I knew there was a problem area and the hygienist did a good job of remaining calm and indicating that he saw the area that was bothering me. When the dentist came in to take a look, the question after looking at my mouth was "What did you do!?" I heard it with an accusatory tone. I also found it unsettling that this interaction happened while I was tipping back/down in the chair so I was looking at her, more or less, upside down. I don't recall being given options for treatment.
