Orthodontist Dr. Michael Mahaffey and His Family

Dr. Mike Mahaffey loves to straighten teeth! A self-professed computer geek, he especially loves using the newest orthodontic technology. He would like to show you how you can get to your ideal smile in an easier and more predictable way than ever before.

Dr. Mahaffey and his wife, Lisa, have three boys, Blake, Mason, and Clark. Family time is very important to them, and they enjoy their trips to the North Carolina mountains, or to downtown Atlanta to meet Mason at Georgia Tech. Hanging around the back yard grilling on the Green Egg can be awesome, too.

In his spare time, Dr. M. helps lead MENTORise, a group of business people in our area who volunteer to mentor aspiring entrepreneurs. He also enjoys golf and tennis, and he is an active member of Southside Church. He also serves on the board of Line Creek Brewery, our new local craft brewer.

Dr. Eric Linkous and his wife Kara recently moved to Peachtree City from Memphis, Tennessee where they spent the last seven years completing his dental school and orthodontic residency at the University of Tennessee and her master’s degree in speech pathology. Dr. Linkous can’t get over the amazing opportunity it is to work in the profession of orthodontics which allows him to build relationships with patients and witness the transformation that takes place throughout orthodontic treatment. There is nothing more rewarding than being part of uncovering a patient’s best smile!

Dr. Linkous loves playing tennis but enjoys playing or watching almost any sport. Originally from East Tennessee, Dr. Linkous particularly loves rooting for the UT Vols; however, Kara regularly tries to convince him to switch allegiance to her alma mater of UGA. He and Kara are passionate about being an active part of a church community and have taken multiple mission trips to places like Guatemala, Kenya, Tanzania, and India. This has caused them to love experimenting with new foods and discovering new cultures. One of their favorite things to do as a couple is to have friends and neighbors into their home for a meal. In Memphis, they were regularly involved in mentoring students and young couples and look forward to investing in the Peachtree City community in a similar manner.

Dr. Linkous is eager to join the Mahaffey Orthodontics team to continue providing ideal smiles with a top-notch patient experience. He and Kara are excited to be involved in the Peachtree City community and to explore the golf cart trails! They can’t wait to meet you!
