For 26 years, Calleva has held true to its mission to provide outdoor experiences that challenge individuals towards personal growth, encourage teamwork and provide enriching relief from the stress of city life.

Founded as a small summer camp in 1993 by Nick, Alex and Matt Markoff, Calleva has built a reputation for excellence and innovation in outdoor education and outdoor adventure. Calleva now works with more than 100 schools and partner organizations in the D.C. area, offering a dynamic set of programs that goes well beyond summer camp to include overnight wilderness experiences, environmental education and small-scale sustainable farming.

The Markoffs are quick to say that their journey has been full of surprises and adventures that have stretched their imaginations. They credit Calleva’s success to a strong team of committed and capable professionals who are passionate about education, the outdoors and community.
