Summer Camp Options

STEPPING UP

ACE
13-16 years old
In All Camp Experience (ACE), campers will participate in classic camp activities along with specialized experiences led by “expert” activity leaders. Whether it be basketball, arts & crafts, magic, or STEM, ACE is the place to come explore everything camp has to offer!
EXCURSION
13-16 years old
In this unique travel camp, campers in Excursion will spend the week on various field trips to local places of interest. Navy Pier, Great America, The Milwaukee Zoo, and The Wisconsin Dells Water Park have all been highlights in the past! The itinerary changes every year, but the joy of adventure remains the same!
WATERSPORTS
13-16 years old
Love the water? This camp is for you! Participants can plan to spend their session enjoying fun in the water in many different ways – water fights, swimming, paddle boarding, snorkeling, and SCUBA certification just to name a few. And that’s not all – come experience fun on land with campfires, outdoor movies, and more!
CAMPCRAFT
13-16 years old
Campcraft is geared towards the teen adventurer! Participants live, eat, learn and play outdoors. Campcrafters sleep in tents that they pitch, eat food that they cook, and gather round the campfire every night to strum guitars, roast marshmallows, and bond over the day’s events. In Campcraft, lasting friendships are built through teamwork, togetherness, and a true love for the outdoors.
EXCEL
17-19 years old
In Excel, friendships – whether lifelong or newfound – are really what it’s all about. Time spent bonding over conversation is just as important as volleyball, swimming, or Chopped food challenges. Excel campers will revel in their favorite camp activities in their last years as campers while serving as role models for the younger kids on campus.

Summer Camp Testimonials
“The program staff continue to knock it out of the park. My daughter came home with a full heart and beyond happy.”
-Camper parent
“My camper was so excited to share her experience with her (non cancer kiddo) friends. I feel like she is more willing to share with them that she survived cancer after her Camp One Step experience – she is not afraid to talk about it.”
-Camper parent
“Thank you for offering this amazing opportunity for her to connect with others, play and just have fun! She has been so isolated through this journey through a new life after treatment, and these camp experiences help so much with boosting her comfort level to interact with others. We are so grateful for all you do! Thanks!”
-Camper parent

Our Medical Team

Camp One Step’s Medical Director, Susie Burke, leads our volunteer medical team. The Camp One Step medical team is comprised of volunteer physicians and nurses who have a passion for working with children and adolescents who are or have experienced the challenges of a life threatening illness. Even though it is important to have staff with pediatric oncology experience, we also welcome staff with other clinical backgrounds such as general pediatrics, adult oncology, emergency, and ICU to name a few. The medical staff work closely together in teams to address the medical needs of each camper. Our goal is to promote the health and well-being of the campers in an atmosphere of fun.
More Camps. More Fun.
