As a stalwart of various bar associations and foundations in Texas, Mark Shank is well-known and respected by the broad legal community – including opposing counsel – in and out of the courtroom. He is known as a strategist, arbitrator, mediator, negotiator, and active member of his legal and civic communities in Texas, the region, and elsewhere in the U.S.. Mark’s practice is focused on complex disputes, which he arbitrates, investigates, prosecutes, or defends as a neutral across the nation.

For nearly 40 years, clients in a wide variety of sectors have sought out Mark’s guidance and counsel. These include:

  • Oilfield Services and Energy Enterprises
  • Technology Companies
  • Banking and Financial Services
  • Multi-level Marketing
  • Telecommunications
  • Manufacturing
  • Health Care
  • Service Industries
  • Executives

Mark regularly serves as an arbitrator and mediator in business disputes, and is also regularly asked to serve as an independent investigator. He is Board Certified in Civil Trial Law and Labor and Employment Law by the Texas Board of Legal Specialization and is an arbitrator for the American Arbitration Association and other providers.  Mark also helps his clients on both sides of the docket with difficult business problems, including departing employees, high-exposure contract claims, business disputes, trade secrets claims involving potential officer and director liability, employment discrimination, wage and hour disputes and retaliation cases. He also has deep experience with cases involving covenants not-to-compete, confidentiality and trade secrets. Mark regularly represents clients in disputes and transactions involving executive compensation and related issues.

Mark lectures often on current arbitration, business, employment and trade secret issues, and is a prolific author, including the definitive book on Texas law as it treats departing employees. “My clients continue to have problems dealing with non-compete and payment issues,” according to Mark. He notes there is also hostility in Congress and among many shareholders about executive compensation. “My job is to help them navigate by using the tools available to them, and when I am a neutral, to help reach a fair resolution."
