Cleveland-based midsize firm Ulmer & Berne will combine with Midwestern boutique Kaufman & Co. next year to expand its trial expertise, the firm announced Tuesday.

All 10 of Kaufman & Co.’s attorneys will be joining Ulmer, including four partners, four of counsel and two associates, when the merger takes effect Jan. 1. The move will also expand Ulmer’s presence on the East Coast, as Kaufman & Co. has offices in Washington, D.C., and New York.
