​Paula Crawford

Hello, I'm Paula your dental hygienist here at Rivertree Dental. Helping our patients and their families achieve their best overall health is my priority as a health care provider. I am passionate about making our patients smile, and feel better about themselves and their health. I am fortunate to have found a practice which supports and encourages my philosophy of patient centered care. I am continuously learning all I can about oral and systemic health, to be a resource for our patients whether questions are about teeth or nutrition. We are truly making a difference in our patients' lives.

In my free time I enjoy hanging out with my family and friends, cooking, traveling, and getting outside. I am also a certified health and wellness coach and I teach fitness classes on the weekends.

Being part of Rivertree Dental is so rewarding. Whether it's a simple filling or full mouth cosmetics, it feels great to help our patients achieve their dental health goals. The quality of dentistry we provide our patients is absolutely the best. I am proud of the smiles we create.  I have had the honor of working with Dr Mayer for more than 20 years. First as a dental assistant and now as the financial coordinator for the practice.

I'm a proud mom to two great kids and a happy wife to a super husband. Our family plays at the beach as often as we can.
