I spent many years fearing of going to a new dentist ever since my old dentist retired during COVID…read more(uncertain dental insurance policies/plans, trusting dentists, etc...). I discovered Hsieh Dentistry thanks to my wife and got to work with Dr. Willis Hsieh. He's super informative, patient, and educational in how to take care of my teeth. He explained to me my options in terms of issues I had with my teeth (deep cleanings, wisdom teeth erupting, etc...). He was never pushy about a procedure, and simply gave his recommendation and what was urgent that should be taken care of. I came out knowing more and feeling secure. He was also quick, yet gentle/thorough with cleaning my teeth as well as replacing an old chipped filling I had (got it ~10 years ago from my old dentist) which started to decay my tooth. Fortunately, we caught it pretty early on and I didn't need a root canal. Everyone at the office is really kind and sweet. The front office, who's ran by Wendy, was very patient in explaining how my dental insurance works and everyone there from the dentist, front office, and assistants were professional and made me comfortable in every way. I was always scared to go to a dentist since 2020, but I feel taken care of here and I think I just found my forever dental office/dentist with the team that works there!

This dentist 100% recommends Dr. Willis. I was really impressed by the efficiency of his assistant when she took X-rays. The intraoral camera is awesome because Dr. Willis can show you where the problems are. I like the fact that he also takes his time to review everything with you. Nothing is rushed and feels calm, relaxed, and zen, much like Dr. Willis himself. Got my cleaning done, got my teeth flossed and polished, and a fluoride application and I couldn't be happier. I need to come back for some work (bummer), but I know I'll be in good hands. Appointments are easy to make and you get lots of text reminders. Thank you Dr. Willis and his staff!

I just completed dental surgery with Dr. Han and couldn't be more relieved with how well it went. I…read morehad been putting it off for over a year, part procrastination and part nerves, until my dentist finally insisted it was time. From the moment the procedure began, Dr. Han put me at ease. She walked me through every step in real time, explained exactly what she was doing, and checked in on me constantly throughout. Despite how anxious I was, her calm confidence and her team's professionalism made the entire experience truly painless with zero discomfort. The care and thoroughness does not stop after the procedure either. She and her team remain attentive and genuinely invested in every patient's outcome. I have several follow-up appointments ahead and another surgery scheduled later this year. I am so grateful it is her doing it. Highly recommend Dr. Han to anyone who has been putting off a procedure out of fear. You are in great hands!

Since December of last year, I've had some tooth sensitivity to hot and cold foods and drinks in my…read moreupper right jaw. Since I get regular cleanings and checkups on my teeth, I didn't think much of it until I started feeling some incredibly intense jaw pain all of a sudden early summer, and for a more than a couple of weeks, I relied on Advil, soft foods at room temperature, and late night video game binges to distract me from the immense discomfort I was going through. I was eventually referred to by my dentist to Valley Green Endodontics and boy am I glad he did. There appeared to be a hard to spot (even by x-ray) hairline crack in a tooth that was found only by removing the filling...and thus the root canal proceeded thereafter. Now, I gotta admit I am terrified of having any work done on my teeth due to - I get incredibly anxious feeling trapped in the chair with the sound of a drill going on. But I was lucky enough to get Dr. Chun, who is as kind and reassuring as she is really knowledgeable as well as super skilled and steady with her tools. She communicated well with me what would happen each step of the way and I felt absolutely no discomfort whatsoever throughout the entire process. Her assistant was also incredible as well. The rest of staff was incredibly nice and easy to talk to and I was happy that my pain - as well as any very mild swelling due to the root canal that happened - subsided pretty quickly. I do need to note although insurance covered a good portion of the root canal, it did not cover the Gentle Wave treatment, which I still thought was worth it for the more thorough cleaning. Overall, thanks so much Valley Green Endodontics, for making a root canal as comforting as it could be!

Yvette always made sure I was comfortable, offered me water and headphones to relax, very sweet and easy to talk to.

I had a very frustrating experience with this office. I waited months for my procedure because we…read morewere waiting on Medi-Cal approval, and throughout that entire time, communication was extremely poor. They repeatedly said they would call and follow up with insurance, but they didn't. We had to constantly chase them down ourselves just to get updates. After finally getting approved, they scheduled my procedure a month in advance--only to call the day before and cancel, saying the dentist was sick. They also said they couldn't reschedule at that time. What made things worse is when we called back with Medi-Cal on the line, they gave a completely different reason, saying the dentist had a family emergency. They couldn't even keep their story straight. This level of disorganization, lack of communication, and inconsistency is unacceptable--especially when patients are waiting months for necessary care. I would not recommend this office.
