Over the years (past 10+ years) I have received excellent care from Dr. Mahon and his staff. He is a conservative dentist who truly cares about preventative medicine. He offers a plan for people like me without dental insurance to keep up on our regular cleanings, x-rays, and exams. Dr. Mahon is very calm and soft spoken, he reminds me of my childhood dentist, a steady person who develops trust. If you want to have a chatty conversation about his family, you need to see his wife who is a hygienist there. they are a great team. I have seen all 3 hygienists at the office over the years and I can't say enough about them-- all great hygienists and great personalities as well! Never had a bad experience! They do book quite a way out, and they are worth it. I just presented to the office with major tooth pain, they got me in right away and my x-ray and exam was covered under my preventative plan. They referred me to a really good provider for a root canal. Now I have to present back to them for a filling or crown and I know I am in good hands. read more

Siena Dental gives great service. The office is pleasant and Brea is a great hygienist. read more

Went in for a filling and was met instantly by the hygienist and escorted to my room. The dentist àrrived shortly thereafter and greeted me and started the procedure. Everyone was courteous and professional. read more

Super happy with Siena Dental. I love how the Dentist is not "crown crazy" and he believes in keeping your natural tooth as long as possible and doing what he can to restore it. I came here after needing in a second opinion because a pervious Dentist that was closer to my house wanted to give me four crowns. I thought it was a little crazy and I'm so glad I got a second opinion. Really love the office. Thank you! read more

The office runs smoothly which makes going to the dentist that much easier! read more

I have been going to Sienna Dental for a few years now. The quality of care is "top notch". For $200 per year you get two cleanings, X-rays and a dentist exam. I was recommended to Sienna Dental by the past 8 year president of the Nevada Dental Association. I couldn't be more pleased with Sienna and the staff. read more

Phenomenal practice, dentist and hygienist. I worked in dentistry for some time and can tell you this crew is solid. I appreciate how well run they are. Dr. Is courteous, tells it straight, and you can tell his staff respect and like him. The hygienists are very helpful, prep you well for your cleaning and are very professional. My dental assistant got x rays done quickly. I highly recommend. read more

Best dentist ever!!!

I've been coming to a dental for about 20 years give or take and I have always received excellent service. Even when the ownership changed from one doctor to another, the quality of care stayed excellent the office is always nice and clean, and as a kid, I always enjoyed watching the fish in the fish tank in the lobby. The staff has always treated me with respect, kindness and utmost professionalism. I highly recommend seeing dental to anyone looking for a quality dental care! read more

Things haven't changed at Siena Dental since I started going there for all my dental needs. And this is good news! This time, it was to correct a bite that was bothering me after an accident. Dr. Mahon and his staff took the necessary x-rays, performed a thorough exam for nerve and tooth damage. He proceeded to do a minor reshape of a tooth and it made a huge difference in my being able to chew normally again! It is fun to eat again! Since the pandemic is still with us, the office staff Covid 19 protocol is strictly followed with temperature checks, masks, gloves, and hand sanitizing. I feel safe when I take off my mask for the dental work each time I come here. read more
