Jeannie and Jonathan Lavine: Leading With Heart

How Jeannie, Jonathan, and the Lavine Family are Emboldening a Community to Fight Rare Cancers

Cancer Affects Us All

Cancer has affected our family personally, something far too many people can relate to. Jonathan’s parents are both survivors of non-Hodgkin lymphoma. Our future son-in-law, Nathan, was diagnosed with cancer in 2019. Today, he has an excellent prognosis, thanks to the ingenuity of his care team and the amazing drugs that are now available. We’re dedicated to supporting cancer research because effective early detection methods and novel therapies allow doctors to save more lives.

Joining the Movement to Beat Rare Cancers

We have been participating in Cycle for Survival, Memorial Sloan Kettering’s movement to beat rare cancers, for more than a decade. Marc and Lori Lavine, Jonathan’s brother and sister-in-law, originally encouraged us to get involved. Marc is a long-time Cycle for Survival leader and a key advocate for the cause. Since 2009, he has served as a captain of top fundraising teams and has cycled in events every year, including as an Extreme Rider — cycling for four hours nonstop! His relentless enthusiasm inspires us every day. I have never seen anything like the energy and devotion that comes from the Cycle for Survival community. We’re so proud that over 350 employees from Jonathan’s company, Bain Capital, have participated in a Cycle for Survival event in Boston, Chicago, New York, and San Francisco since 2013 and collectively raised more than $2.1 million.


Helping Cycle for Survival Participants Maximize Their Impact

The need for sustained research funding is urgent. In January 2021, we launched the Crimson Lion / Lavine Family Foundation Match to Inspire to help Cycle for Survival participants push their fundraising further by matching leadership gifts. This match builds on our previous sponsorship of the Million Match Challenge, which generated nearly $30 million for rare cancer research led by MSK between 2015 and 2020.


MSK Is Synonymous With Innovation

MSK is a leader in drug development, operating one of the largest clinical research programs in in the world. We’re thankful to the physicians and scientists who devote their lives to developing new treatments. We hope our contributions give them the ability to continue to pursue bold ideas. 


It is crucial that we continue to raise money for new treatment options. Cancer doesn’t stop, and I know this community will never stop either.

Looking Forward

Just a decade ago, many people with a rare cancer didn’t have any treatment options for fighting their disease. Increased donor support from peer-to-peer fundraising efforts has led to new life-changing treatments. We’re proud supporters of Cycle for Survival and will be until there is an effective way to treat every rare cancer.
