  • Profile
  • Experience
  • Professional + Civic

As a partner at Gammage & Burnham, Greg specializes in litigation and bankruptcy law. He has considerable experience in every phase of the litigation process—pre-suit investigation and analysis, pleadings and motion practice, depositions and other forms of discovery, trials and evidentiary hearings, appellate briefing, and post-judgment enforcement.  He has been lead counsel on multi-million dollar lawsuits, and he has handled heavy caseloads.  The types of cases vary, but they often involve a debtor-creditor relationship.  Greg is particularly experienced in litigating disputes over business contracts, property valuation, bankruptcy issues, community property, and fraudulent transfers.

Greg has appeared in courts across the state:  superior courts in almost every county, federal district and bankruptcy courts, and even multiple justice courts and tribal courts. He has written articles and given presentations on a variety of legal topics, mostly related to bankruptcy or debt collection.

Greg was born and raised in the Midwest. He joined Gammage & Burnham in 2005 after graduating with honors from the University of Michigan Law School. During his undergraduate studies at Adrian College, Greg earned perfect grades in two majors (mathematics and political science) while also competing for the varsity cross country and track teams.

Greg serves on the board of directors of Valley Youth Theatre, a non-profit organization in Phoenix.  He recently completed a six-year stint as Secretary of the state bar’s bankruptcy section.  In the past, Greg has volunteered with Arizona Town Hall, Arizona High School Mock Trial, and the Mountain Park Health Clinic/ASU Center for Family Justice.
