Being a dentist is a dream come true and I'm thankful to be able to do what I love, every day! It’s an honor to work with each and every patient who entrusts me with their care.
I completed my undergraduate degree at James Madison University, in Harrisonburg, VA and, following graduation, worked in the genetic support lab at Howard Hughes Medical Institute for several years. I then enrolled in dental school and earned my Doctor of Dental Surgery degree (DDS) from Virginia Commonwealth University. During my time as a dental student, I excelled in endodontics and was selected to perform complicated root canal cases for not only my patients, but also my classmate’s patients. This was an honor I carry with me to this day!
Following graduation, I attended a General Practice Residency at Hunter Holmes McGuire Veterans Hospital, where I was able to advance my knowledge and skill set in the field of prosthodontics, periodontics and oral surgery. During the first year of the COVID pandemic, I remained in the hospital and had the honor of performing emergency treatment such as root canals and extractions, for the veterans who were most vulnerable and required care. Following this I worked for a family practice in Fredericksburg, Virginia until relocating to Colorado.
In my free time I enjoy skiing and hiking with my husband, sewing clothes and accents for my home, and reading books outside. I am very excited to be working at Cozy Dental Kids & Family, and look forward to meeting all of you!
