Mark combines years of success defending class actions and handling other major litigation with the practical experience of leading an AmLaw 125 firm and a career's worth of focus in legal ethics and professional responsibility.


Following a very successful 11-year service as Managing Partner of Stinson, Mark enthusiastically returns to practice with the goal of using his legal and practical experience and expertise to better service the firm's business clients as well as other lawyers and law firms. Mark already had an impressive resume of commercial litigation success, leading teams defending cases with up to 10 figures at issue. During his tenure as managing partner of the firm, he added the business and practical experience of serving as CEO of a professional organization with $270M in revenues and 500 lawyers. Throughout his career, Mark has also maintained an expertise in legal professional responsibility and ethics, writing, speaking and having served as the Firm's general counsel. With Mark's return to active practice in mid-2021, he intends to build on these areas to provide leadership in commercial litigation for clients, and to build and expand on a practice in legal ethics and professional responsibility, both within the firm, assisting the firm's current general counsel; and to service other lawyers and law firms with "second opinions,"  training programs, expert witness services, legal malpractice defense and mediation/arbitration.


Mark served as managing partner of the firm from July 1, 2010 – June 30, 2021, deputy managing partner from July 1, 2008 – June 30, 2010. In this role, Mark served as full-time CEO of the firm responsible for leadership of and strategy relating to all business and practice operations.

Before being asked to assume the managing partner role, Mark served as one of the firm's leading trial lawyers, routinely handling eight to ten figure matters for key clients across the United States. In recognition of his experience and success, he was inducted as a Fellow of the American College of Trial Lawyers while still in his 40s. He served as national Chair of the ACTL's Attorney-Client Relationships Committee.

Committed throughout his career to professional responsibility, he frequently writes and presents on the subject, and served for a period of years as general counsel or co-general counsel of the firm.

Mark co-founded and presents "Ethics for Good," which uses humor, skits and real-world scenarios in stage productions to teach legal ethics to lawyers. All proceeds (about $850,000 so far) go to charities and legal scholarships.
