Christina “Tina” Tchen plans on applying a broad bird’s eye view of the globe, which she learned from her previous job as chief of staff to former First Lady Michelle Obama, in her new role as a partner and head of the Chicago office at 150-lawyer Buckley Sandler.

Buckley Sandler announced Tuesday its hire of Tchen to lead its office in the Windy City, where the Washington, D.C.-based firm opened an office in 2013. Tchen brings to Buckley Sandler a unique blend of expertise in commercial litigation, government enforcement and regulatory affairs work.
