Experience

Prior to his service as managing partner, Mark served as one of the firm's leading trial lawyers, representing business and governmental clients across the nation, including class action defense, with amounts in dispute routinely in eight and nine figures, and multiple cases with more than $1 billion at issue. He was elected as a fellow of the American College of Trial Lawyers (ACTL) while still in his 40s.

Mark served as general counsel or co-general counsel of the firm from 1996-2008, at which time he became deputy managing partner, then managing partner from 2010-June 30, 2021. In his role as managing partner, in addition to expanding the firm and improving its financial performance and diversity (and diversity of its leadership), he served as decision-maker on legal and ethics matters for the firm, with the advice of the firm's general counsel and counsel team. Upon returning to practice, Mark has focused on legal ethics and professional responsibility and also serves as a member of the firm counsel team, providing advice on a daily basis to the firm's lawyers and other constituents concerning legal ethics and professional responsibility.

Mark chaired the ACTL's National Standing Committee on the Attorney Client Relationship, and now serves as a member of that committee. He is the original author of the document that became the ACTL's "White Paper" on Attorney Client Privilege Issues. Mark has been a member of the Kansas Bar Association's Professional Ethics Advisory Committee from 1997 to present. He is a member of the American Bar Association Center for Professional Responsibility, and served on that group's Publications Board from 2006-2009.
