Love them! We love the Zebra Bucks system and the kind staff. I love that they have matching outfits! We are now going on to our next child in ortho…we will continue to use Dr. D!!

Professional, Nice and the Best!

5 Stars for Petaluma Orthodontics!

The staff and care at Dr. Woo and Dr. D’s office are incredibly professional, nice, and probably the best orthodontists in the north bay. My wife was a patient a decade ago and now I had braces put on as an adult. They are very great and I can’t wait to see my smile in another year and a half. I would recommend them to anyone and especially children since they definitely put you at ease and are a lot of fun!

Wonderful Things to Say!

5 Stars for Petaluma Orthodontics!

I have only wonderful things to say about the orthodontic care my two children have received at this office. Dr. Deberardinis, specifically, has provided the best care for both my son and daughter. The office staff is top-notch and so incredibly friendly. We have had the unfortunate issue of having to come in on weekends for emergencies and, no matter who the technician is on call, they never complain about having to come in on their days off. There is always a friendly smile greeting you upon entering the office as well as leaving. Truly a wonderful practice with staff who care about their patients and the success of their smiles 🙂 -Tiffany E.

Smiling Hugely!

I love my new smile! After I left I smiled hugely for over an hour and a half without stopping. Everyone here was really nice and helpful. Thank you so much!

Thanks Again!

Thank you very much for my beautiful, and healthy smile! And for all you did to work with me and make it a painless and pleasant experience. Dr. Woo and staff are just the best there is! I always looked forward to coming in and seeing everyone and sharing life and laughs. You are all part of the family. Christmas cookies will be coming! Thanks again, I miss you already!

We Couldn’t Be Happier –

5 Stars for Petaluma Orthodontics!

I highly recommend Dr. Woo and Dr. Deberadinis for orthodontic treatment.  My 10 year old daughter and husband have both received great orthodontic care, my daughter had braces and my husband has invisilign. The staff is friendly, patient and professional.  They explain everything thouroughly, including finances.  Also, when I called after hours with a concern about my daughter, they responded within a short amount of time.  We couldn’t be happier;  it’s nice to know their are still professionals who provide quality affordable services for personal health care. – Christine H

So Pleased!

I could not have been more pleased with the treatment I received from this practice. Dr. Woo was so knowledgeable and caring – and tenacious! I am so delighted with my result. His entire staff, from reception to technicians, orient themselves to the well-being of patients. It’s never too late for a perfect smile! THE BEST!

A great time!

I had a great time here. Every staff member here treated me nicely. Everyone was a professional. I would do it over again!

I am so excited!


I am so excited to have my new smile. even though the process was long, I think it was well worth the wait. Thank you Dr. Woo and Dr. DeBerardinis for helping me achieve my smile.
