What Our Patients Say About Us

5.0

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!

5.0

I had to switch dentists after I changed to another Medicare Advantage plan, so I did some research, read some reviews, and chose Las Posas. Just had my initial visit and wow, I think I made a VERY good choice. They have a great staff and state-of-the-art equipment. Dr. Chaichian was very personable and explained everything she did. Turned out I needed a crown on a cracked tooth that was also hiding the beginnings of a cavity, and they got it done in two hours, with minimal discomfort to me. A plus (for me anyway) is that they are in a good shopping area with a Sprouts and Marshalls and Home Goods, restaurants and more, so it's not one of those medical-dental only complexes. Highly recommend!

5.0

All staff are friendly and helpful. Dr. Tran and Camille are great, always give great advice and do a wonderful job. My 1st visit dated back in 2017, recommended few of my close friends to use Las Posas Dental as well. Overall, a place I can trust.
