Our Mission & Camps

Since 1978, Camp One Step has brought happiness, support, strength, and hope to hundreds of campers and their families each year.

Our FREE in-person camps and CONNECTED digital programs serve kids with cancer (whether newly diagnosed, in-treatment, or in remission), their siblings, and even their parents.   Inclusion, accessibility, connections and empowerment are core to our mission.  At Camp One Step, kids make forever friendships, reclaim childhood, and families feel whole again.

Camp is not a place, it is a community!

Thanks to our community of campers, families, over 400 volunteers, and generous supporters, the magic of camp can be felt anytime, anywhere.
