A group of mostly East Bay Jews is running to raise money for the Leukemia and Lymphoma Society.

They call themselves Team Jon.

The 15 runners on the team hope to help their friend Jon Galinson, a member of Berkeley Congregation Netivot Shalom. Galinson has chronic lymphocyctic leukemia, or CCL, a cancer of the blood and bone marrow.

Galinson has been through 10 rounds of chemotherapy but needs a bone marrow transplant. Two bone marrow drives in June at Israel in the Gardens and at Netivot Shalom registered 400 donors. But the chances of finding a match were slim — one in a million — and none was found.

Team Jon members are preparing for the Nike Women’s Half Marathon with Team in Training. The race is Oct. 18 in San Francisco.

Most runners on Team Jon are fellow members of Netivot; several — like Jon and his wife, Yael — are parents of Netivot preschoolers. The Galinsons sent their oldest daughter, Gaby, 5, to preschool at Netivot Shalom for the past two years.

Team Jon hopes to raise $50,000 for the Leukemia and Lymphoma Society, which funds research, clinical trials, education and patient services.

Members of Team Jon include Jon’s wife, Yael Galinson, who has already raised $10,500; Elizabeth Creditor, wife of Netivot Rabbi Menachem Creditor; Debra Massey, director of education at Berkeley Congregation Beth El; and Eliana Wolpe, wife of Los Angeles Rabbi David Wolpe.
