For many members of the armed services — active and retired — security clearance becomes a defining characteristic of a successful military career. If your security clearance is in danger of being revoked, it is wise to seek the counsel of a skilled military lawyer as soon as possible.

At the law firm of William E. Cassara, PC, we have more than 30 years of experience representing military personnel through a wide range of legal processes. Our founding attorney has extensive experience representing service members from all branches of the armed forces. When you need knowledge, experience and tenacity on your side, don't hesitate to schedule a free consultation at our firm.

Security clearance issues can ultimately lead to discharge from the service and limit your future employment opportunities. If you believe you are under investigation or are worried about losing your security clearance, it is important to work with an experienced attorney as soon as possible. We can thoroughly investigate your situation and provide valuable insight and tenacious defense throughout the legal process.

Denied Security Clearance Attorney

Additionally, our firm is well-equipped to represent military clients who have been denied security clearance. If your request has been denied, you still have options. We will review your case and determine the root cause of your denial. Once we gain a clear understanding of your situation, we can develop an effective strategy that supports your desire to attain a security clearance.

Whether you are facing suspension, revocation or reclassification of security clearance, we encourage you to contact our firm as soon as possible.

If you have further questions regarding military law or defense, contact William E. Cassara, PC. We provide representation to clients throughout Georgia and nationwide in a wide range of matters. We can be reached by phone at 800-511-9293 or through our easy online contact form to schedule a free consultation.


Experience Counts

Mr. Cassara has over 30 years of experience representing service members and civilians appeal the loss of a security clearance. In addition, attorney Ed Allan, who is "of counsel" to the firm, recently retired as the technical authority and principal attorney providing legal support to the Army's largest Counterintelligence and Counterterrorism investigative organization.  Between us we have over 50 years of experience in security clearance cases. Mr. Allan is located near Washington, D.C., and Mr. Cassara's principal office is near Fort Gordon, GA, the headquarters of the military's Cyber Command.  As such, we are keenly aware of how to navigate the security clearance landscape.  If you are facing the loss of your clearance, or appealing the denial of a clearance, contact Mr. Cassara for a free consultation.
