Our patients say.

“I wish I could give them 10 stars! This was my first time here and they were so incredibly friendly. The office is very clean and modern. I loved Dr. Katy! She is so sweet, patient, and understanding. I was a little nervous since I’m getting my wisdom teeth out, but after meeting with Dr. Katy and her staff, I’m feeling a lot more comfortable about the whole process. Awesome dentist all around!!”

Gina B.

“Our whole family sees Dr. Katy and Dr. Nguyen and we have nothing but compliments for this office. They are experts in their profession and actually care for their patients. I've gotten some complex work done here plus the basic exams and cleanings and it's always been a good experience.”

Marcus J.

“I was going to a local dentist here for years and became very unhappy because I felt like they were looking for ways to jack up the prices.”

Vanessa P.

“I came in for a cleaning & the hygienist did a great job. The first time I ever felt that my teeth were clean after a cleaning. The hygienist even took the time to floss between my wire retainer. Everyone was very professional & engaging. I highly recommend.”

Sane R.

“The staff are very accommodating. The place has a calm and hygienic ambiance. Victoria and Dr. Mieu really did a good job in explaining and doing the procedures. The best dental clinic so far I’ve ever been too.”

Keith A.

“Great experience at Dentist Tree. The staff are all very friendly. They do a great job of explaining any issues and treatment options. The office is modern, comfortable and clean. The TV’s overhead with Netflix are a great distraction while they are working.”
