Michelle Chan, DDS
I was born and raised in New York, but made my way out west to earn my DDS from the University of Colorado School of Dental Medicine, and have been in love with Colorado since!
My mission is to help our community and patients feel confident with their smiles, and focus on creating a comfortable environment where you feel heard.
When I’m not in the office, I’m always looking for new restaurants and unique foods to try. If you have any favorite spots, please let me know about it while you’re in our chair!
