Managing Partner, Houston Office

Mark has focused on complex litigation and counseling for nearly 30 years, with extensive experience in the areas of energy, construction, refining, petrochemicals and industrial operations. His combination of substantial outside trial experience and in-house global litigation responsibility positions him to understand the needs and earn the trust of clients, both in contentious disputes and proactive risk avoidance.

Mark handles major and complex litigation matters in many areas, including engineering and construction projects, joint venture relationships, commercial and contractual disputes, major personal injury claims, and incidents.

Following years as outside counsel for various clients, Mark joined a leading global refining and chemical company, where he served as 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, proactive risk avoidance, and 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 joined DLA Piper in 2017, blending his knowledge of business client needs into his global practice.

Mark's substantial 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.
