HOLLANDER--Phyllis Isabelle.

On July 13, 2023 at the age of 94, this lifelong New Yorker left behind a legacy of love, activism, and dedication to her community. Born and raised on the Upper West Side, attended Hunter High School, Allegheny College and the University of Michigan. Summers at Camp Red Wing on Schroon Lake were cherished. Briefly resided in Baldwin, NY, but her true love and passion was New York City. She embraced all New York City had to offer and lived independently until 94. Always active in the arts, culture, politics, women, disabilities, and civil and human rights. Her life extended beyond her activism as a celebrated volunteer in the Glass Garden Horticulture Program at NYU-Rusk working within the hospital especially with children who had cancer. Also loved gardening on the High Line and Central Park Conservancy well into her 80's and at her treasured home in Millerton, NY. She worked as a social worker and collaborated with her husband and on her own editing and writing sports books. Known for her unwavering dedication to others and as a caregiver and loyal friend to many. Preceded in death by husband, Zander, and son, Peter. Survived by daughter, Susan (son-in-law, Neil Whitman), sister, Davee Israel, as well as cherished granddaughters, Tobye (Isada) and Emma (Andrew), great- grandchildren, Patrick and Zuri who brought her great joy and her special caregiver Andrea Cordova. Donations to a charity of your choice in her memory are welcome. Her legacy of compassion and dedication to making the world a better place will continue to inspire all those who knew and loved her.
