Leslie Train Westreich passed away peacefully on September 27, 2026, at the age of 84. Born in Scarsdale, New York, Leslie made the Washington, D.C., area her home for more than 40 years. The beloved matriarch of her family, she was at the heart of bringing generations together and creating the traditions and memories they will carry forward.

She is survived by her deeply loved children, Timothy Landres and Claudia Helmig; her son-in-law, Timothy Helmig; and her stepchildren, Lauren Emerson, Dana Hirt, and Anthony (Tanya) Westreich. She was the proud “Lelly” of Megan, Matthew, and Jacob Landres; Camille, Charlotte, and William “Billy” Helmig; Greta and Nathaniel Emerson; Oliver, Kalie, and Quincy Hirt; Max and Gabriel Westreich; and Tobey, Olivia, and Juliette Beyer.

She is also survived by her treasured sister, Felice Londa, and her loving nieces and nephews, Jessica (Pavel) and Peter (Claire) Londa, Emily (Peter) Martin, and Andrea (John) Falco.

Leslie lived with a rare and radiant sense of her own spirit. She moved through the world on her own terms, embraced each day with zest, and possessed an extraordinary capacity for joy. Her creative dinners and parties were legendary, as were the playful gifts and unexpected surprises she delighted in leaving for the people she loved.

Leslie brought that same warmth and openness to her work as a therapist and to the many passions that filled her life. She loved golf, decorating, entertaining, the arts, and theater, and deeply valued education and lifelong learning. A generous philanthropist and active member of Woodmont Country Club, she proudly held the title of women’s golf club champion. Above all, her family was the center of her life, and there was nothing she would not do for those she loved.

She will be deeply missed and forever remembered for her zany personality, infectious laughter, sharp intellect, boundless generosity, and fierce devotion to her family. Her memory will remain a lasting light in the lives of all who knew and loved her.

A funeral service will be held on Friday, October 9 at 1:00 p.m. At Garden of Remembrance Memorial Park, 14321 Comus Rd, Clarksburg, MD 20871. In celebration of Leslie’s vibrant spirit, guests are encouraged to wear colorful attire rather than black.

The family will receive guests on Saturday, October 10, beginning at 6:00 p.m., with a Shiva Minyan service at 7:30 p.m.
