WAPO has the obituary for Philip ("Phil") Brennan,
here, reporting that he died on 8/1/19. Very nice obituary. The memorial service is Wednesday, Aug 14 at 12:30 p.m. at The Old Presbyterian Meeting House. Other information is in the obituary.
On his DOJ work, the obituary says:
After graduating from Fairfield University (where he played baseball), he attended Georgetown Law School. Dad had a long and very successful career at the Dept. of Justice where he worked in the area of voting rights in the Civil Rights Division under Attorney General Robert F. Kennedy and later as a Federal Prosecutor in the Tax Division.
But then on the different side:
Later in life, Dad went back to school and got his doctorate in Clinical Psychology from The Fielding Institute in Santa Barbara Ca. Dad started The Ethos Foundation in the mid 70's with the focus on healing families with alcohol and drug addiction. He lived his faith which was to help people heal. Dad was compassionate and an excellent listener. He practiced Clinical Psychology until his 86th birthday. Dad's hobbies were traveling, cooking, watching the Washington Nationals and lying in the sun. Dad always started his day with daily devotions and Bible reading.
