Misty Mackey, RDH

Misty joined the Dental Center of Aspen Hill family in November of 2018. She is truly grateful and thankful for having found a great team to work with everyday. Meeting new people and establishing relationships with her patient is what hygienist Misty enjoys the most about her job. Misty's patients like her friendliness and her willingness to explain treatments in terms they can understand. She enjoys talking to her patients about their oral health.

When she is not in the office Misty enjoy spending time with her friends and family, especially her young son, listening to music, creating art and reading books on any and all topics.
