Equal Justice

Under the Law

I've been an attorney for over forty years. I'm a Board Certified Criminal Law and Labor & Employment Law Specialist. I started my legal career as a prosecutor with the Ramsey County Attorrney's Office and public defender with the Hennepin County Public Defender, both in Minnesota; was a partner in Saint Paul, Minnesota criminal and labor law firm; and co-founded Hughes &Costello in 1992, as a criminal labor, and employment law firm.

Additionally, I have tried hundreds of criminal cases, arbitrations and administrative proceedings involving labor and employment law issues, representing individuals, unions, and employers in Washington, D.C., New York, Minnesota, Iowa, and the Dakotas. I also served as Counsel to the International Brotherhood of Teamsters, General Secretary-Treasurer's office in Washington, D.C. from 1999-2012.

I'm the Author of Minnesota Misdemeanors (Lexis-Nexis); Co-author of Minnesota Evidentiary Foundations (Lexis-Nexis); Hating the Sin, Loving the Sinner (Garland Publishing, Inc.) and a Contributor Editor to The Developing Labor Law (BNA).
