After attending law school at the University of San Diego in California, he was immediately hired by Watson, Nathan, & Bremer, P.C., as a law clerk.

He has appeared before the Division of Workers’ Compensation at both the hearing and appellate levels. His practice includes insurance law and defense of civil actions founded in professional liability, insurance bad faith, product liability claims and negligence in courts throughout Colorado and before the United States District Court. Mark is a member of the Colorado Defense Lawyers Association, the Defense Research Institute, the Colorado Bar Association and the Elbert County Bar Association.
