Testimonials

Could not ask for a better experience from Marty and his team! From my first visit they made me feel so comfortable. Marty filled in some gaps I had wanted filled for over 20 years and they're absolutely perfect. He even called to check on me after having to be seen for a bad infection I had acquired. Will be switching my children over to him as well. Can't say enough good things about Sierra Dental!

As one who has a strong dislike of folks playing around in my mouth, I found Dr. Marty and staff to be courteous and very professional and the same time very friendly!! They were all very sympathetic to my needs. Thanks guys!

Dr. Marty and his staff provide the highest quality dental care I have ever experienced. They truly treat it as an art. This was the first time I have had cavities filled that I did not feel pain once during the entire process.. WOW!! Sierra Dental has mastered the ability to make patients feel at ease and at home during every appointment!! Thank you all for enhancing smiles every day!

This was the best experience I’ve ever had at a dental clinic! Dr. Williams is an excellent dentist who’s main priority is making sure his patient is comfortable and gives the best dentistry there is. He and his dental assistants where so unbelievably nice! I had a crown put in and never thought I’d get out of the chair saying 'this was an awesome experience, I don’t want to leave!' I’ve had absolutely everything done to my teeth through the years and I so wish I had known about Sierra Dental instead of experiencing the pain and lack of care I had to from other dentist. I will forever recommend Dr. Williams, his staff and practice to all and will only go here from now on. Thank you again!
