Kansas City, Missouri-based Shook, Hardy & Bacon has added to its Philadelphia office, bringing on a litigator from Morgan, Lewis & Bockius.

Thomas Sullivan is the 10th lawyer to join Shook Hardy's Philadelphia location, which opened in 2012, according to the firm's website. Morgan Lewis has nearly 300 lawyers in Philadelphia, where it was founded, and over 2,200 worldwide, according to the firm.

Sean Wajert, Shook Hardy's managing partner in the city, said Sullivan adds bench depth in Philadelphia, where the firm is looking to grow.

Sullivan focuses on complex litigation, including class actions and mass torts. He also handles cases alleging fraud in state and federal health care statutes, as well as legal ethics and professional responsibility matters. His work has focused largely on the life sciences and food and beverage industries.

“I'm going to be hitting the ground running with this premier litigation firm and its outstanding trial and appellate lawyers,” Sullivan said in a statement.

Sullivan's clients, according to federal court records, have included Rite Aid, Ward Manufacturing, Auxilium Pharmaceuticals and Urban Outfitters. He represented Urban Outfitters in a consumer class action over the collection of customer zip codes for marketing purposes in Massachusetts—an issue on which he has represented several national retailers.

“We've known Tom for a while. He's got a great reputation in town and we're excited in particular because his practice focus and his practice mix is such a wonderful fit for what we do and what we're trying to do here,” Wajert said in an interview.

In a statement, Shook Hardy chair Madeleine McDonough said Sullivan will help lead the development of the firm's practice with health, life sciences and food and beverage clients.

The firm already has a foothold in the region with some of those clients, having recently represented Johnson & Johnson in local talc litigation and Boston Scientific in pelvic mesh litigation that originated in Philadelphia.

Sullivan spent more than 14 years at Morgan Lewis, which has nearly doubled in size since he joined in 2003.

Shook Hardy had a total head count of 467 and gross revenue of $350.7 million in 2017, Legal affiliate The American Lawyer has reported.

Wajert said Shook Hardy currently has 13 timekeepers in Philadelphia.

“We don't have a magic number, but I would think when we get to about 20 or so we'll take a breath and assess what's next,” Wajert said.

A spokeswoman for Morgan Lewis said the firm wishes Sullivan well.
