New dentist for me after moving far away from former trusted dentist. Modern office with up to date equipment and computerized x-ray facility. Prompt response to emergency issue. Friendly staff, obvious competence that I recognized from many dentists helping me over the years

I've been going to Dr. Mayher for at least 10 years. I've recommended a lot of friends a coworkers to her. It's a family based practice with a wonderful care, great quality and friendly stuff.
