Kristin is a Florida native but has spent most of her life her in Madison. She graduated from Bob Jones High School in 2006. She developed a passion for the dental field after a car accident landed her in a dental office for six months to correct her smile. That same office offered her a position as a dental assistant.

After some time as an assistant, she realized she wanted to pursue a career in dental hygiene. She graduated from Calhoun Community College with an Associate of Science degree in 2011. She then
completed her Associate in Dental Hygiene from Wallace State in 2014. Kristin has no doubt that selecting a career in dental hygiene is the best decision she has ever made. She is committed to
providing quality care for her patients.

Shauna has been in the practice for over ten years where she has treated our patients with great compassion and care. Ensuring that every patient has a comfortable, positive, and informative experience in our office is what Shauna strives for every day.

She believes that one of the most rewarding aspects of her career is to see the transformation of all our dental family, either from the treatment that they have completed or simply helping them with dental anxiety. In her spare time, she enjoys spending time outdoors with her dogs.


Chris is the office manager, or the "OM," according to the staff. She has been serving our office and our patients, who are like family to her, as the office manager for the past nine years. Chris is also a Certified Pharmacy Technician and has worked for Kroger since she was 17 years old. After 21 years with Kroger, she decided to expand her horizons and enter the dental field.

There are several similarities between the pharmacy and dental fields that made her transition between the two seamless. One of the most important, and most notable similarities, is helping patients understand their future dental needs and understanding their insurance benefits.

Outside of work, Chris spends time with her husband, two children and four grandchildren. In her spare time, she likes traveling, going to the beach, and spending time with friends and family.
