Mark has focused on complex commercial litigation in the energy and construction industries for more than 20 years, with extensive experience in the area of refining and petrochemicals. His combination of substantial outside trial experience and in-house global litigation responsibility positions him to understand the needs and earn the trust of business and industrial clients. 

Mark handles major and complex litigation matters in many areas, including engineering and construction projects, oil and gas and other energy disputes, joint venture relationships, commercial and contractual disputes, equipment failures and matters relating to complex plant operations. These include commercial, personal injury and third party claims from major incidents and disruption to operations.

He comes to DLA Piper from a leading refining and chemical company, where he served as head of global litigation and oversaw high-value disputes, advised C-level executives and led the company's legal health, safety and environmental functions. His role included analyzing and advising on contentious matters that were early in their development to determine if they could be resolved without formal legal proceedings, as well as serving as the lead legal department advisor for the company's Crisis Management Team, which is responsible 24/7 for corporate emergency response in the event of any incidents worldwide.

Mark's trial experience allowed him to earn certification in Civil Trial Law by the Texas Board of Legal Specialization. He has held that distinction since 2004.
