What Our Patients Say About Us

5.0

9 months after the review below - I wanted to update it. Changed to 5 stars from 3 because of the excellent treatment by Dr. Chaichian. She demonstrates that she really cares by listening to my concerns and offering great suggestions for treatment without being rude or pushy. Also want to mention Camille the hygienist who greets me as an old friend. She makes her recommendations very kindly- again, not pushy. Finally the front desk staff are very friendly and helpful. OLDER REVIEW We’ve been going to this office for two years now and are usually very happy with the care we receive. It was my first time seeing Dr. Tran, and I just wish he was more compassionate. He didn’t seem to have noticed that everything was good at my last visit, and came across as blaming me for not taking care of my teeth this time just because I had a 5. It would have been nice if he had taken more time to show care instead of seeming to want to rush on to the next patient.

My whole family has been going to Las Posas Dental for over 10 years now, and we couldn’t be happier. Going to the dentist has always given me anxiety, but their team consistently makes me feel comfortable and cared for. Dr. Tran is incredibly patient and understanding, which makes such a difference for me. I truly wouldn’t go to anyone else. Camille is a wonderful hygienist—she does a thorough job while always being gentle and attentive to my needs. Claudia and Lynnay also go above and beyond to make every visit smooth and positive. The entire team genuinely cares about their patients. Thank you all for everything you do!

Las Posas made my dental plan so easy and straightforward. Dr. Chaichian was amazing. I have a fear of the dentist and she made me feel so calm and walked me through everything! Highly recommend!
