Meet The Team

Pulaski Family Dentistry | Meet The Team | Cynthia M. Southern, DDS

Sandy Southern

Sandy is usually the first friendly face you will see upon arrival to our office. She is most likely the voice on the other end when you call. Sandy is energetic and eager to assist you with appointment needs and general information.

She most enjoys spending time with her 7 very active grandchildren (3 of which are Dr Southern’s children). Sandy loves all things Halloween and spends lots of time and energy planning a yearly Spooky Trail for all the office and neighborhood kids!

Brenda Young, CDA

Brenda has been with our office since the very beginning. She is the widow of Dr Donald Martin, founder of this family practice and Dr Southern’s mother. Brenda, along with Dr Martin and now Dr Southern, has strived to provide the best care for our patients since 1975. She is very active and passionate about the overall health of herself and others!

Brenda has an abbreviated work week, but can be found assisting the Doctor on Monday and Tuesday evenings.

Debbie Alley

Debbie has worked in most areas of our office and now primarily assists Dr Southern with all things restorative. She started here with Dr Cindys father, Dr Martin, and continues to excel and hone her skills.

Debbie is happily married to state trooper Roger Alley. She has 3 grown children and 3 grandchildren.

Don Southern

You will recognize Don right away either in the office or on the phone as the only man on staff. Bless his heart! This fact alone must speak for his patience and character. He also now handles all things concerning insurance and scheduling. He is Dr Southern’s husband and, with 10 female coworkers, probably has a longer list of “honey-do’s” than any man in history.

Primarily, Don is our lab technician. He constructs our beautiful same-day crowns, bleach trays, retainers, occlusal guards, surgical stents, etc. If you have inquiries about our same-day crowns or any other lab-assisted procedures he can help you. Any questions about fishing, soccer, or Virginia Tech football should also be directed to Don!


Kellie Deu, RDH

Kellie hails from nearby Dublin and has attempted several professions over the years. She feels that God led her to the dental field where she has practiced dental hygiene for 17 years.

She’s crazy in love with her husband, Jim and their 3 children: Grayson, Mahlon and Ily. She’s an active follower of Jesus and feels blessed to be part of our team. Kellie enjoys the outdoors with her family and friends and she admits to being a Pinterest addict!

Cailyn Parker

Cailyn is from Bland County and loves all things having to do with their family farm!. She primarily assists on the preventive side of the office.
