Founded in 2010 by federal defense attorney Nick Oberheiden, Ph.D., today, Oberheiden, P.C. has a network of highly-experienced attorneys and legal professionals who work collaboratively to defend clients across the United States in high-stakes federal matters. This network includes several former federal prosecutors, including former U.S. Attorneys, former Assistant U.S. Attorneys, and former U.S. Department of Justice (DOJ) trial lawyers who collectively have centuries of combined experience on both sides of federal investigations, trials, and appeals.

Our attorneys also routinely meet with prospective and existing clients at their offices and facilities, and our client list includes individuals and businesses in over 40 states. Whether through our attorneys’ federal bar admissions or affiliations with Local Counsel, we are able to represent clients in all federal jurisdictions nationwide.
