I just moved here in Feb of this year and finally found a place to continue my dental care and I cannot say enough how wonderful my experience was at Sierra Dental. The personal touch along with the incredible amount of thorough examination and having everything laid out and explained. Sierra Dental is awesome from Doc Martin to everyone on the staff, Ashley and Jessica and everyone you guys rock!

After receiving care here, you won't want to go anywhere else. The environment is always clean and comfy. The staff members are professional without being stuffy. We have had some great conversations! They also have an office dog who is super sweet, for anyone who is nervous about going to the dentist. The care received at Sierra Dental can't be beat. If Dr. Williams has to be away, they have a partner office you can see in case of emergency.

We love Sierra Dental! Katie and Liza are my kid’s hygienists and they are wonderful! They recently showed my 10 year old a fun, easy way to floss and he’s been doing it daily! My 6 year old loves the treat at the end along with their sparkle flavored toothpaste! Marty is very thorough and does a great job!! Of course, we love seeing Charlie as well!! We highly recommend Sierra Dental!!

Marty and his staff are very caring & compassionate.... and “Charlie” (the dental office doggie) just topped it off and was AMAZING and made me feel much more relaxed than I have in the past with going to other dental places!!
