Erin is the dental hygienist at Willow Lake Dental. She earned her associate degree in dental hygiene at Argosy University in 2010 and is a graduate of Mounds View High School (2002).

Erin likes working at Willow Lake Dental because the staff here is very thorough, and cares about giving patients the best care possible. She would like current and potential patients to know that Dr. Tracy and her staff are very caring and always work hard to make patients comfortable.
