Experienced Security Clearance Attorneys

Our attorneys specialize in security clearance appeals.  They have dedicated their careers to learning the entire security clearance process from start to finish.  They started by working for the federal government before entering private practice.  Their extensive experience working for the federal government includes over eight years advising clients on revoking and suspending an employee’s security clearance, reporting derogatory information, representing clients in their response to a Statement of Reasons (SOR), and serving in a joint duty assignment for the Defense Office of Hearings and Appeals (DOHA).  Their work at the DOHA allowed them to learn the inner-workings of the Agency responsible for representing the Department of Defense Central Adjudicative Facility (DoD CAF). All of these experiences provide our attorneys a unique advantage over other attorneys and firms who practice in the security clearance niche.
