Spooky season is here! 🎃 🪦 👻
It feels wrong decorating for Halloween when it's 80 degrees outside 😂

Halloween is coming! Patients in braces can still enjoy lots of candy, like Reese's, Hershey's, York, 3 Musketeers, and more. Avoid sticky, chewy, crunchy candy like Milk Duds, Nerds, Caramel, etc. Everything in our Witch's Brew cauldron is ortho-approved👌🏻🦷

Our Halloween contest starts today! Guess how many marshmallows are in the jar to win a $50 gift card AND an electric toothbrush OR water flosser!
Make your guess in-office, via email, or social media. Contest ends Oct 31. Contest limited to patients, please 😁
Good luck! ☠️🎃👻🖤🧡

This feels like a lifetime ago! Many of our patients never saw our space before the buildout. This photo was taken where the dental chair open bay is now. Love the way it turned out 😊
