FayeFaye Sewell  

My career in the dental profession started in 1980.   I will forever be grateful for the opportunity of working for Dr. Robert Joiner from 1982 until his retirement in 2014. I was also priviledged to work with Dr. Edward Rohmer and Dr. Thomas Miller until retirements as well. Through the past thirty five years , as office manager of Advanced Dental Associates, I have experienced the joy of helping provide the highest quality dental care for third and fourth generations of families, who have been long established patients of this practice.

My husband Robert and I have been married for fifty five years and we have two adult children and one beautiful granddaughter, Katie, who just graduated from Mercer Univesity in Macon, GA.

We enjoy spending time with our family and staying active in our church.  My hobbies are gardening, canning, sewing, and baking.
