Message from John Mahoney, Esq., Attorney at Law

“First of all, thank you for your public service to our nation and the American people as a federal employee. I’m sorry you’re experiencing employment difficulties with the federal government. Don’t worry any more though, because I’m a federal employee lawyer who has effectively represented thousands of federal employees, like you, in federal employment and security clearance law matters throughout the U.S. and around the world for over 20 years.

In 2014, I left my last large D.C. law firm, where I was a partner and the Chairman of the Labor & Employment Law Practice Group, and where I supervised dozens of federal employee lawyers in the litigation of thousands of federal employment law cases each year. I really wanted to get back to being able to personally represent my clients as I prosecute or defend their federal employment law cases. The bottom line is that I missed being a federal employee lawyer, and I am honored to be able to again personally help people protect, defend, and enhance their federal careers.”
