About Me

I possesses a unique combination of formal legal education and experience, senior U.S. government service and   operational field experience.  


I am a successful litigator who engages in federal and state criminal defense, visa and immigration benefits, immigration removal defense, administrative law defense and a wide variety of complex civil litigation. 


Before joining in the private legal field, I served with the United States Customs Service and U.S. Customs and Border Protection (CBP).  These positions consisted of all levels of the organization; National Director, interim Border Enforcement Coordinator, Assistant Port Director, Chief Inspector, Supervisor, and Senior Inspector.  I served in these positions throughout the United States/Mexico Border region, internationally, and in Washington, D.C.


My service as a senior government manager includes policy development, data analysis systems development, Congressional affairs, budget allocation, human resources / labor union liaison work, and advanced targeting systems.


I focused my highly decorated field career on all aspects of federal law enforcement special operations, interdiction, immigration, investigations and intelligence.  My enforcement experience includes counter terrorism, international narcotics trafficking, weapons trafficking, intellectual property rights enforcement, fraud, money laundering, bulk cash smuggling, human trafficking and others.  


I have developed, taught and supervised advanced inter-modal interdiction training for military and law enforcement officials from the United States, Latin America, Eastern European countries, Russia, Hong Kong and others.  This work focused on counter-proliferation and arms trafficking interdiction, as well as systems processing problems identification and enhancement. 


I am a veteran of the United States Navy and has been awarded the Armed Services Expeditionary Medal

    I endorse this lawyer. We have worked together as opposing counsel on family law matters in the past, and I found him to be highly professional, competent and an effective communicator. Since then, Mr. A'Hern has helped some of my clients with immigration matters, and I would not hesitate to send future immigration clients to Mr. A'Hern. With his extensive background in customs and immigration enforcement, he has a great knowledge base and high integrity.
