Jones Day will pick up four health care lawyers from Squire Sanders, including former practice head David Grauer, after the firm’s partnership votes on a proposed merger with Patton Boggs this week.

Squire Sanders partners Scott Edelstein in Washington and John Kirsner and Lisa Han in Columbus will join Grauer in the move, according to sources familiar with the reshuffling. The four attorneys work on transactional and regulatory legal issues in health care, primarily helping insurance, hospital and health system clients, including Cleveland Clinic.

The partners resigned from Squire Sanders in April. But Squire Sanders said it wouldn’t allow the partners to leave for 60 days, according to the sources.

The partners’ 60-day stay at their former firm is unusual. Most laterals move to new firms 12 hours to one or two weeks after they give notice. Some firms, including Squire Sanders, write 30- or 60-day notice provisions into partnership agreements. Yet firms rarely enforce those clauses, according to Washington legal recruiter Dan Binstock.

“Usually they feel it’s in the best interest of everybody for the partners to move to their new home … and cut the cord,” said Binstock of Garrison & Sisson.

Squire Sanders said in a statement Tuesday: “We wish these colleagues well and would like to thank them for their contributions to the firm. With over 110 lawyers practicing in various areas of health care law, Squire Sanders maintains one of the industry’s leading health care practices under the leadership of Columbus partner and president of the American Health Lawyers Association Peter Pavarini.”

Pavarini took over as head of the group after Grauer gave his notice.

The news falls against the backdrop of the proposed Squire Sanders/Patton Boggs tie-up, which would give the larger firm the cache of Patton Boggs’ Washington lobbying work.

Patton Boggs partners began voting on the merger Tuesday. Two sources familiar with the process said Squire Sanders also votes this week, over the course of a few days.

Jones Day health care practice leader James Dutro declined to comment about the new hires.

Reuters reported Tuesday night the merger would be effective June 1, with the new firm named Squire Patton Boggs.
