Dr. Petty & Dr. Bielik have always been highly recommended by my Dentist. My son needed a consultation for his teeth and of course my Dentist referred me to Dr. Petty & Dr. Bielik. We trust them 100% and we’re happy with the outcome of the appointment.

This was my first appointment for a fitting for invisalign. The office was up to date, clean and the staff was beyond nice and knowledgeable. I would recommend anyone that needs an orthodontist to consider visiting this office.

When I first came to Petty & Bielik, my teeth were quite literally all over the place. When I was done, it was my senior year of high school, and I received the “best smile” superlative out of my entire class. They know what they’re doing!

The staff was very friendly and make you feel welcome as soon as you walk in the door. I was nervous for my appointment but everyone was great and explained things every step of the way. I’m looking forward to starting my Invisalign treatment!

I went to Dr. Petty when I was a teenager. All three of my children have also gone here. They are the best staff; so friendly and efficient. Also, the office is so clean and modern. I highly recommend Petty & Bielek!
