Mary Anne “Bitsy” Brennan, age 62, of Chevy Chase, MD, passed away peacefully on June 7, 2025, after a short illness from complications from heart surgery. Bitsy was born on July 20, 1962, to Donald J. and Mary Cronin. She was the devoted wife to Edward G. Brennan whom she married on April 11, 1992, and the proud mother to both Edward Gerard, and Ryan Alexander Brennan.
Bitsy was a graduate of the National Cathedral School (1980) and The University of Alabama (1984). After graduating UA, Bitsy worked in the Washington, DC area for Paine Webber/UBS Financial, and was a teacher at Bethesda Community School, and finally at Our Lady of Lourdes. Bitsy was known for her giving spirit, boundless energy, and her ability to make everyone that she met feel like a close friend, which left everyone she encountered, both young and old, with a lasting impression that endures today.
As we celebrate her life, we should all know that Bitsy lived life to its fullest! She enjoyed good wine, margaritas, long days at the beach or pool, and just spending time with her family and countless friends who she loved unconditionally! Her generous heart, quick wit, beautiful smile, and vibrant presence will deeply be missed but never forgotten.
