What People Are Saying…

I am forever thankful to Dr. Parker for her tenacious dedication and even-keeled temperament, negotiating a minefield of oversight and apathy on a USG personal clearance reinvestigation. The background wasn’t complicated, but the incredible depth of officials’ mishandling, and steps she orchestrated and untangled in restoring my TS-SCI have ensured my continued employability in a 40-year career of service to our nation. Her immense network of contacts, in and outside of the USG, coupled with her exceptional credentials and experience, easily puts her in a class by herself. …a true professional.
