Mark A. Rosenbaum

Mark Allen Rosenbaum of Short Hills, NJ passed away peacefully following a brief illness on Monday, December 1, at Morristown Medical Center. He was surrounded by family and an immeasurable amount of love. He was 80.

Mark was raised in Wynnewood, PA and graduated from Central High School where he was a member of the tennis team. He continued his education at the University of Pittsburgh, majoring in economics and Chinese (being the only one in his class), and was a member Pi Lambda Phi fraternity, and graduated in 1967. He then attended Temple University School of Law and graduated first in his class in 1971. In 1973 he graduated with an LLM in tax law from New York University School of Law. He began his career at the Manhattan-based law firm of Webster & Sheffield where he became a partner. In 1991 he joined Stroock & Stroock & Lavan as a partner and remained there until his retirement. During his youth, he worked at various Philadelphia stadiums selling snacks and drinks, actively participated in the Boy Scouts of America and worked at The Johnson Wax Pavilion at the 1964-65 New York World’s Fair.

To those who knew Mark, he was a devoted and reliable friend who was often sought out for guidance and advice that he was always available and more than happy to provide. He was an avid supporter of Israel and Jewish causes and an active member of his synagogue, Temple B’nai Abraham in Livingston, NJ, where he was a member of the board of trustees. He loved his Thursday night poker game that started in 1974 and was a diehard Yankee fan, even through the eighties. More than anything, though, Mark’s love and commitment to his family were immeasurable. No matter how demanding his professional obligations, he somehow always managed to be there for every single moment, no matter how big or small, that mattered. Many of his greatest memories involved the multiple trips to several continents that he enjoyed over the years with his wife and children. Only three years ago, Mark finally achieved his dream of bringing all three generations of his family to Israel.

Mark is survived by his wife of 56 years, Sandra (Sandi) Zissu, three children and their spouses, Richard Rosenbaum (Kim), Jill Krasnove (Brett) and Peter Rosenbaum (Lori), and 10 grandchildren, Lindsay, Finn, K.C. and Harley Rosenbaum; Charlie, Simon and Kate Krasnove; and Benjamin, Tyler and Cooper Rosenbaum. He is survived by his sister, Nadine Tolvin (Jeff), 11 nieces and nephews and 25 great nieces and nephews. He leaves a massive hole in the heart of the large family gatherings and events that he loved so much.

He had a lifelong habit of reading the obituaries, something his children always found amusing. He said it was because he always found it fascinating to read how different people lived their lives. He is no doubt reading his own now and his children would want him to know how hard they tried to capture what was a great life lived by an even greater man.

The family will receive guests at Temple B'nai Abraham, located at 300 E Northfield Rd, Livingston, New Jersey, on December 4, 2025, from 10:15 am to 10:45 am.

A funeral service will follow at the same location, starting at 11:00 am.

Burial will take place at B'nai Abraham Memorial Park, located at 2600 US Rt. 22 East, Union, New Jersey, at 12:30 pm on the same day.
