Diane B. Patrick (née Bemus; born December 17, 1951) is an American lawyer specializing in labor and employment law.

[4] John Charles Bemus, who enlisted in the United States Navy at the age of 16, had to pass as completely white in order to work on a naval ship outside of a galley kitchen.

[4] He was trained as an electrician by the U.S. Navy and served on board a minesweeper which protected Allied supply routes to the Soviet Union during World War II.

[1][5] Diane Patrick's maternal grandfather was Bertram L. Baker, a New York politician who immigrated to the United States from Nevis in the then-British West Indies in 1915.

[8] She was raised in Bedford–Stuyvesant, where she lived in a brownstone with her extended family, including her parents, her brother and sister, grandparents, an aunt, cousins, and two dogs.

[1][11] She then moved to Los Angeles to attend Loyola Law School, where she received a full scholarship and earned her Juris Doctor in 1980.

"[1] She was twenty-five years old when she was introduced to Deval Patrick, a recent Harvard Law graduate who had also moved to Los Angeles to clerk for a judge.

[1] Upon returning to Massachusetts, Patrick joined Ropes & Gray, a well-known Boston law firm, in 1995, as a labor and employment attorney.

[16] Governor Deval Patrick contemplated his resignation in response to the toll the campaign and public life was taking on his wife.

[14] Some observers felt that the first lady would have to leave her law career, but Patrick expanded her role at the firm during this time.

[2] In 2015, soon after leaving the position of state first lady, Patrick was inducted into the Academy of Distinguished Bostonians and received the Cushing-Gavin Management Attorney Award for Excellence from the Labor Guild of Boston.

[9][19][18] Deval Patrick initially declined to run for President of the United States in 2020 due to his wife's cancer diagnosis.

Diane Patrick has served as a trustee for several organizations, including ArtsBoston, Brigham and Women's Hospital, Cambridge College, and the Massachusetts Maritime Academy.
