I waited a short time in the waiting room, which was comfortable and nicely decorated, before being escorted to exam area. After a moment, my dentist arrived, reviewed my chart, and listened to my questions before ordering an x-ray and examining my problem tooth. He quickly determined that I required a root canal and provided a list of local endodontist. Dr. Greif and the entire staff were wonderful, calm and professional.

From the minute we walked in we were greeted by the very friendly office staff. They interacted with my daughter and were very sweet and kind. Dr. Ernst was amazing. He was so friendly and really did a nice job explaining everything to my daughter and I. He was very patient with my daughter. I would highly recommend him to anyone for eye care needs. We received exceptional care!

My dog had to have x rays. I was not asked if I wanted to view the x rays. I was given two pain pills which my dog did not need, he is not in any pain. I felt I was slammed with expense not needed. I have been taking my dog to this clinic for 13 years and previous animals before that. I have probably been doing business here for over 30 years. Disappointed this clinic now makes me feel like they are all about making money than caring about my animal.
