We try to make our office as welcoming and home-like for our patients as possible, since we believe that comfort and trust are the biggest factors in a positive experience at the dentist.
We also strive to accommodate our patients’ busy schedules. We’re open Monday through Thursday from 7 A.M. to 3 P.M., and we offer flexible appointments. We also have two hygienists on staff for your convenience in scheduling cleanings.

Excellent service and professional care! I really enjoy Dr. Nellis staff and knowledge of dental care.
Love everything about this office from check in, to check out! Dr. Nellis genuinely cares for his patients, and takes the time to answer any questions you may have. Love Dr. Nellis and his staff. Always a smooth experience.
My wife and I have been seeing Josh for nearly 20 years. Until I switched to him I thought going to the dentist had to be painful. Josh and his hygienists are gentle yet thorough. Friendly and helped too. Because they do such a great job of maintenance the only dental procedure I've had is to replace a filling I got when I was 10. Great guy. Great staff. Great dentist.
Really like this office and their whole crew. DeDe is the best hygienist ever! This should explain how great this office is. I am moving over an hour away and will still be using this office as my primary Dentist for routine cleanings and anything else that can be scheduled.
Hands down the best dentist and staff I have ever experienced!
Dr. Nellis and team were great. I felt very comfortable during the process and Highly Recommend this team of professionals! Dr. Nellis and his staff are the best. Dr. Nellis always takes time for his patients and his care is truly top notch. He is caring and goes above and beyond for his patients which is very hard to find these days. I’ve always had a fear of the dentist since I was a little girl and I can honestly say that went away after I saw Dr. Nellis.
This was my first visit and the staff was very welcoming and made the process extremely easy and fast. Dr. Nellis and his staff were very informative and knew exactly what they were doing. I’m awaiting treatment plan from Dr. Nellis and will continue to see him for all of my dental needs! I have finally found the dentist I will use for years to come!
