A Love for My Patients’ Healthy, Beautiful Smiles

As a dentist, I’m in a unique position to change people’s lives for the better, every day. Whether I’m restoring someone’s ability to chew properly and comfortably, moving them out of dental pain, or improving their smile, I’m increasing their quality of life.


As I’m working to improve their dental health, I’m getting to know each person. I love the stories they share and being included in their life. It’s a great feeling when a person opens up to me and lets me know about who they are beyond the dental chair: that level of trust is humbling.


My father was a dentist here in Sonora for almost 30 years. Hearing him speak about the work he did, and the relationships he built with his patients, helped me decide that dentistry was the right path for me. I have no doubt I made the right decision by following in his footsteps.




"I was very pleased with the staff at Thorn Family Dental! They were friendly and informative and made the experience a positive one. I will recommend them to family and friends!"

Dr. Thorn and his assistant were personable and explained each procedure as they went along. They made sure I was comfortable at all times and the experience was painless. The staff has always been friendly and I appreciate them. I've been coming to the same dental facility for over forty years and through the changes during those times the integrity remains the same. Dr. Thorn even telephoned me personally to see how I was doing a few hours later. Thank you

"My son broke a filling off at school and I called and they fit us into their schedule for the next day. They even accommodated  an after school appointment (4 pm). We hadn't seen a dentist in over 2 years but he saw us and fixed the broken filling on the spot (I was expecting to have to come back). The staff was super friendly and Dr. Thorn was great. My son is very nervous about shots but Dr. Thorn made the experience quick, calm and painless. My son was very happy. I highly recommend Dr. Thorn and have to family and friends."

"I have seen several dentists over the years, and my dental care has been a patchwork of good and bad providers. Dr. Thorn and his staff are some of the most professional, pleasant, and genuine I have experienced. They worked quickly and efficiently to solve my dental issues within my budget!"

After being a patient of Charlene Chu for over 20 years, transitioning to a new dentist was a bit frightening. Dr. Chu was a perfectionist and I trusted her completely with my dental care. But YAY, along comes Dr. Thorn and he is caring and gentle and very professional while still being friendly and easy to communicate with. He and his wonderful staff (Stephanie is a rock star of a dental assistant!) took very good care of me. The removal and replacement of an old crown was painless and during the procedure, they described what they were doing to me every step of the way. I am so happy to be a patient of Dr. Thorn and his exceptional staff!

Everything about my visit was exceptional. The Thorn family team is professional and pleasant to be a around. I "almost" wish I had more cavities just so I could hang out with you guys a little more often. But of course, your exceptional dental care has worked against me in that regard. ;-) Not a cavity in sight! Thank you for a great experience, for communicating so clearly that you care, and for creating an atmosphere of joy that really is a big part of who you are as a team.
