Legal issues are always stressful unless you have good legal counsel. Dennis handled our issues extremely well, communicated every step of the way, and our outcome was way better than anticipated. I highly recommend Dennis as he is the best attorney we have hired in our 15+ years in business.

Mr. Sysko took on our difficult psychological security adjudication case and won. He was thorough in pulling together all the facts and in bringing in expert testimony. We are glad we chose him and his team.

A owe a great deal of gratitude to Mr. Sysco for taking my case. Through the approach he outlined and executed, my proposed clearance denial was overturned on appeal.
Having observed him working my case, he is extremely knowledgeable and experienced on DOD processes and procedures and has great interpersonal and communication skills.

38 years of practicing law is extremely experienced. A law professor with 26 years spent with the NSA and 12 plus in private practice is a niche where few attorneys can practice due to the security clearances required. Dennis knows the law and procedure which is clearly evident in his pro bono contributions here and the fact that he teaches law. His client reviews are stellar. READ THEM! Do yourself a favor and call him for a consultation. If you are lucky he might agree to take your case. KUDOS

I fully endorse Dennis Sysko. I worked with Dennis on a highly complex immigration matter that touched on national security matters. I handled the immigration aspects of the case, where he provided an exceptional expert opinion on the national security/security clearance aspect of the case. His knowledge in this niche area is unsurpassed. I believe his expert opinion won the day in our case. I enthusiastically recommend him to anyone facing a security clearance issue.
