X Rays, Cleaning and inspection
The office has had a digital X-ray machine for some time. Very fast and efficient, allowing immediate takes at new angles if suspicions arise. Doctor and staff are very professional. I have witnessed Dr. Herrera and Brittany, the hygienist, develop their credentials and implemented their newly learned techniques of dental implants, radiology, automatic gum depth measurements and mouth cancer inspection, to name but a few. Always cheerful. Always professional

I broke my plate on Friday just before the Holiday so I was worried about seeing the doctor. My fears were alleviated I received a call back the very next day and was able to come in polish down the sharp edges of the broken plate which stopped the irritation. I was able to set my next appointment date for 4 days later. Perfect.

Friendly, Professional Service
I have been a patient of this office approximately fifteen years (maybe longer). G. Allen Herrera, D.D.S. is a great dentist! He does all sorts of procedures, no pain! I did not have a visit with him today. I had an appointment with the hygienist. She knew her profession well. She took me in early, and completed all services with expertise, and was very friendly.

High Quality Service and Friendly Staff
G. Allen Herrera has been my dentist for a decade. He has always done the best work and had the latest in dentistry equipement. He just did a root canal and made a new four tooth bridge for me. When installing the bridge he was maticulas about getting the fit perfect. I have never had to return for corrections of any kind. He's a hundred mile trip for me but I'd gladly drive further to have him and his wondeful staff serve me.
