    We mourn the passing of our beloved friend Terry. She was a distinguished trademark and copyright attorney, leader and founding partner of GTPP.

    Terry fought brain cancer for nearly five years with strength, dignity and grace, just as she lived every day.  Her zest for life was inspiring. With many interests, her most cherished times were with family and friends, exercise, travel, music, playing guitar and piano, and writing fiction. Although shortened, she had a life well-lived.

    Terry is deeply missed by all that knew her.  Farewell our friend.
