Benefit Honorees

Shari and Nathan J. Lindenbaum
Guests of Honor


Shari and Nathan Lindenbaum each met Sharsheret’s founder, Rochie Shoretz A”H, on their own. Shari attended one of Shasheret’s first parlor meetings and Nathan met Rochie on the Yeshivat Noam board. They each became friends with Rochie, laughed a lot and learned more about Sharsheret. Shari and Nathan knew that Sharsheret was an organization with which they wanted to be involved – especially given Shari’s strong family history of breast cancer and what her radiologist called her “busy breasts.” In 2016, Shari and her sisters dedicated Sharsheret’s Educational Resource Series in honor of their parents, Florence and Joseph Appleman as part of Rochelle’s Dream.

Last year, Shari was diagnosed with a small cancerous mass and became a direct beneficiary of Sharsheret’s help. Shari opted for a bilateral mastectomy with reconstruction. Thankfully, chemo and radiation were not necessary and the surgery went well. In celebration and gratitude, the Lindenbaum children hosted the legendary Boob Voyage: The Breast Party Ever (pictures available upon request).

Nathan has been a lay leader involved with Jewish education for many years. He is a current trustee of SAR, the Federation of Northern New Jersey and Prizmah. Nathan is also a cofounder of TeachNJ and EdPAC. When not investing, Nathan loves to ski.

Shari, a former Pediatric Nurse Practitioner, uses her skills to give (unlicensed) medical advice and worry about her children. She has finally learned to ski, enjoys swimming and taking care of everything her husband doesn’t.

Shari and Nathan have four wonderful children, two of whom are college graduates and two of whom are on their way. All of them can tell breast jokes on command. Shari and Nathan are looking forward to becoming empty-nesters this September and hope to spend more time in Israel.
