UOS @ PS 139 Alexine Fenty School

Under One Sky After School offers holistic and innovative after school programming throughout New York City to promote critical thinking and a sense of wonder for the world around us. Our four core values – respect for one’s self, respect for others, respect for the community, and respect for the environment – guide all aspects of our program, ensuring that students  grow and learn in the process of having an amazing time at after school.  Our UOS After School program is modeled after 130 years of experience designing exciting summer programs. For a full description of the Under One Sky After School program, please visit the general UOS page.

PS 139 is dedicated to creating a nurturing and collaborative school community with opportunities to support social emotional growth for all students – during the school day as well as during after school. This includes leadership development and community involvement with an emphasis on courtesy and kindness. At Trail Blazers, it is our goal to instill these same values in our campers through hands-on learning, positive relationships, and outdoor exploration.
