     In 1970, tragedy struck the Gerstman family when Harvey and Carol Gerstman's daughter, Lisa

Beth, was killed in a summer camp bus accident.Because camp had been such a joy in Lisa Beth's life,

the Gerstmans wanted to start a foundation in her name.They wanted to bring that same summer camp

joy Lisa Beth felt to other children.When Lisa Beth's brother, Dan, heard the Cross Island YMCA

(CIYMCA) was looking for funds to help send physically disabled children to summer camp, he knew

it was the perfect way to keep Lisa Beth's memory alive.

enjoyed camp.The added costs of onetoone care and specialized busing for the disabled children

physical disabilities the opportunity to attend camps in an integrated (综合的) setting.

kids with varying degrees of disabilities.The children were given the opportunity to experience the joys

of summer camp, build lasting friendships and develop their selfconfidence.

      Over the last five years, the Lisa Beth Gerstman Foundation has been partnering with camps that are

willing to launch (发起) integrated programs that include wheelchair accessible transportation, onetoone

swimming instruction, adaptive physical education equipment and training, all in a caring environment

where the children join in all regular camp activities.Last summer, the foundation partnered with six

camps, which allowed a total of 150 physically disabled children to experience summer camp.
