Senior Counsel He / Him / His

Mark S. Stewart is a litigator who served as Chair of the firm for 12 years.

As Chair, Mark led a number of strategic expansions. He oversaw Ballard Spahr's entry into the New York market through cross-practice lateral acquisition and a combination with the white collar defense firm Stillman & Friedman. In 2018, Mark guided the firm in the establishment of its Midwest presence, overseeing its merger with Lindquist & Vennum, which added offices in Minneapolis and Sioux Falls, South Dakota, and bolstered Ballard Spahr's corporate transactional capabilities. Under his direction, the firm developed the nation's premier First Amendment litigation and media law practice, merging with Levine Sullivan Koch & Schulz in 2017 and adding a team from Leopold, Petrich & Smith two years later.

Before becoming Chair, Mark served as Ballard Spahr's Strategic Planning Partner. In that role, he oversaw the opening of offices in Atlanta, Las Vegas, Los Angeles, and Phoenix and the recruitment of lateral partners in every office of the firm. He also was instrumental in the firm’s combination with the Atlanta intellectual property boutique Needle & Rosenberg.
