Mark brings a career-long focus in legal ethics and professional responsibility, with the practical experience of leading a major law firm and success in large litigation.
Upon his return to practice after serving as managing partner of the firm, Mark Hinderks followed a career-long passion and focus to establish and lead the Legal Ethics and Professional Responsibility practice group of Stinson, offering law firms, law departments, lawyers and other clients services that include advice, opinions and second opinions on legal ethics and standard of practice matters, training, consulting and testifying expert witness services, mediation and arbitration and malpractice representation. His goal is to provide informed service to clients, while elevating the standards and knowledge of the profession.
Mark is the author of Dear Ethics Lawyer™, a twice-monthly email newsletter with questions and answers concerning legal ethics, currently circulating to more than 5,000 lawyers. He is a co-founder and presenter of "Ethics for Good," a twice-annual stage show which uses humor, skits and real-world scenarios to teach legal ethics to lawyers. Founded in 2000, it has raised approximately $850,000 to date for charities and scholarships. He has presented more than 125 programs on legal ethics over the past 30 years, has authored 11 articles and handbook chapters on legal ethics, and has been deeply involved in professional organizations with legal ethics and professional responsibility as their focus.
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.
