Community Service

303 Smiles is proud to call Greenwood Village home. Since 2003, Dr. Straffon and our team have helped renew over 4,000 smiles. We love seeing our neighbors smiling.

But sometimes, neighbors need a little extra help. Our team donated to Cherry Creek Cheerleading, and Maddie won with her essay on what a new smile meant to her. Watch her story here.
