I have been a Registered Dental Hygienist for over seven years, and have had the pleasure of working at Mountain Shadows Dental since April 2018. I live in Firestone, Co and really enjoy working here because of the friendly environment and the care we provide our patients. The staff here keeps me smiling throughout the day and my patients provide me with joy.

I was always interested in the medical field, but really knew that a dental career was the way to go for me after I went to observe hygienists, doing what they do best, making people proud of their beautiful smiles! I love what I do and helping patients in even the smallest ways, it makes me want to strive to be the best I can be. I want people to be comfortable and enjoy coming in to see me.

Outside of work, my world revolves around my wonderful husband and three smart, beautiful little girls – Payton, Ariana and McKenzie. Two go to the local school, Imagine Charter School. I love music, reading, watching sports, camping and boating and exploring this great state of Colorado.
