After 17 years of work in the dental field, Christine decided it was time for a career change. She became a full time student at Gwinnett Technical College studying accounting. She received her Associates Degree and was offered an accounting position on her birthday. She has now been a part of this team as a Staff Accountant for almost seven years and is currently working on her Bachelors degree in accounting. Christine has been crowned "The Problem Solver" among her coworkers, and she loves to do just that, for her teammates and for her clients too. When Christine is not at work, she is either spending time with her 11 grandchildren & 7 children, or riding her rhinestone studded Harley that she nicknamed Diamond.
