Katie Mesner-Hage began her career at Koskoff, Koskoff & Bieder in 2013 as the firm’s first Theodore I. Koskoff Public Interest Fellow. With her blend of empathy for her clients and passion for justice, Katie quickly became a valuable asset to the firm. In 2015, she joined Koskoff as an associate.

During her fellowship, Katie became an integral member of the team that brought suit against the manufacturer, distributor, and seller of the weapon used in the Sandy Hook Elementary School shooting on behalf of ten families. Katie was recognized by the Connecticut Law Tribune in its 2015 Personal Injury Hall of Fame for her work with Josh Koskoff in obtaining an 8 million dollar verdict against a physician who failed to diagnose and treat a patient’s depression, resulting in his suicide.

Katie is a 2013 graduate of Yale Law School, where she was a finalist in the Harlan Fiske Stone Moot Court and a member of Yale’s nationally-competitive Trial Advocacy Team. During her time at Yale, Katie worked with the Office of the Public Defender in New Haven and spent her summers in Louisiana and Texas representing indigent clients on death row. Katie was named a Connecticut Bar Foundation Fellow in recognition of her commitment to public interest law. In 2012, Katie served as a judicial intern to the Honorable Shira Scheindlin of the Southern District of New York. Prior to law school, Katie worked as a paralegal for a civil rights law firm in Washington D.C.
