Meet the Dentist

Ashly Cothern, DDS

Dr. Ashly Cothern fell in love with general dentistry from an early age and worked with her family dentist through high school and college. During Dr. Cothern’s fourth year of dental school, she took the initiative to reach out to a local dentist to ask if he needed an associate. After they got to know each other, the dentist said he was ready to retire and wanted Dr. Cothern to buy the practice from him. So she did! That was over 20 years ago. Since then, she has grown the practice substantially from two operatories to seven.

Dr. Cothern thanks God for the amazing team members and patients that have come alongside her throughout the journey. She values the long-term connections and strong relationships with patients that running a smaller boutique practice allows. Patients value seeing familiar faces every time they visit, too, as it eases any dental-related anxieties they have.

Dr. Cothern has been married to her husband Mike for more than 22 years, and they have four children and a 5-year-old black Labrador. Outside of the dental office, she enjoys exercising, keeping up with her kiddos and their activities, and reading.

Dr. Cothern was recently voted one of D Magazine's most influential women for 2023. She is also an independent OPTAVIA Coach – visit her page here.
