Kathleen Weeks

APEX Accelerator Senior Office Manager

Kathleen Weeks has been with the National Center APEX Accelerator since February 2013.  She started her position as the PTAC Administrative Assistant and within a few months was promoted to the PTAC Office Manager.  In October 2016, she took on a dual role as both Interim Executive Assistant and PTAC Office Manager until March of 2017 when she returned to her sole role as the Office Manager.  By 2020 she was wearing hats for multiple roles in addition to her previous duties, including marketing, graphic design, bookkeeping & accounting, and IT/computer maintenance, so thus she was promoted to Senior Office Manager.

Mrs. Weeks is a mother of four, which taught her how to organize everything.  Using this skill, she started volunteer work for the school system in the early 1990’s and was referred to as “the person to go to when you want to get things done” by the Superintendent of Marietta City Schools.  Again, acquiring many varied skills, she moved into the work force, with only a few business courses to show on her resume and almost no professional work history.  She went from substitute teaching, to organizing photo shoots for little league teams, to weekend supervisor for a litigation support services company owned by Brown College of Court Reporting.  Then she proved herself to the company manager and started her administrative role at Litigation Technologies in the late 1990s.

Kathleen has since acquired over 25 years of experience in the administrative management arena where she has handled a vast array of responsibilities from assistant positions to supervisory and management roles.  Her motto is, “I don’t claim to know everything, but if I don’t know it, then I WILL find out”.
