I have been a hygienist for 32 years. I grew up in upstate SC and attended University of South Carolina majoring in Biology before transferring to Greenville Technical College to complete my Dental Hygiene degree. I have worked in Orthodontics, Periodontics, Veterans Administration Dentistry and General Practice. I enjoy GP the most as I see a wide variety of patients with different needs. I have a heart for all patients, but especially the patient that has a fear of dental treatment. I have spent many hours in a dental chair as a patient and I feel that qualifies me to understand and minister to the patient with “dental anxiety.” I am blessed to truly love what I do after 32 years! My hobbies include gardening, fishing, traveling and my muscle car!

While in college and dental school at the University of Kentucky (Lexington, KY), he won numerous awards and then completed a residency in dentistry at Wake Forest University School of Medicine / North Carolina Baptist Hospital (Winston-Salem, NC).

I am a North Carolinian through and through! I was born and raised in Raleigh and attended college and dental school at UNC-Chapel Hill. I was fortunate enough to do my General Practice Residency at MAHEC in 2011-2012….and to get married to my husband Chris who is also a dentist and MAHEC graduate. We moved away for a few years after residency but missed the mountains and soon returned to western North Carolina to stay. I truly enjoy all aspects of general dentistry and my heart is in helping people and treating patients like family. My work in private practice, dental education, and public health is a unique blend and has made me a better dentist, educator, and person. I am very active in continuing education and hold leadership positions in the Buncombe County Dental Society and the North Carolina Academy of General Dentistry. When I am not working I am soaking up quality time with our young daughter, riding my Peloton bike, or out walking our Labradoodle Flossy who we spoil completely rotten.
