Keystone Youth Alliance home, a red-brick Carnegie-library-style building at the corner of a Philadelphia block at golden hour. A deep blue mural runs the length of the side wall.

What young people do when given the room.

Philadelphia, since 2007.

Our work, in three lines.

Three Philadelphia neighborhoods. Twelve to nineteen. The same young people, year after year.

Small cohorts. Adult mentors who stay. Three-year arcs, not single sessions.

What we measure: who came back next year. Not impressions, not reach.

Four programs, run year-round.

After-school, summer, mentoring, college readiness. Each program runs on a three-year arc. Cohort sizes are small on purpose.

After-School

Homework, mentoring, dinner. Open Monday through Thursday from three to seven.

Ages 12–19 · Three neighborhoods

Summer Programs

Method

Small cohorts. Mentors who stay. Three years, not three weeks.

Most youth programs run on cohort sizes too large to know each young person individually. Ours do not. After-school cohorts cap at twelve. Mentoring is one-to-one for a minimum of two years. Summer cohorts at twenty-four.

Mentors are volunteer Philadelphians, vetted and trained over a four-month onboarding. The matched pair commits to two years before the first conversation. The young person is not a project. The mentor is not a service.

Cohort cap Twelve, after-school.
Mentor commitment Two years minimum.
Programme arc Three years.
Buildings Three. South, North, West.

The Alliance

Staff. Mentor. Participant.

Three voices. The same buildings. Different roles in the same work.

The young people don’t need our enthusiasm. They need us to show up at four o’clock on a Wednesday in February.

Renee Thompson Executive Director · South Philadelphia

Two years in, we stopped talking about basketball. We started talking about what he wants his life to look like at twenty-five.

Marcus Hill Volunteer mentor since 2022 · North Philadelphia

I came in seventh grade for the homework table. I’m here in twelfth because of the people who never moved on.

A moment from the work

An hour with a mentor at a wooden table.

Wednesday, four-fifteen. The South Philadelphia building is full. A volunteer mentor and a fourteen-year-old are working on a science project at the long oak table by the window. The mentor is a retired structural engineer. The fourteen-year-old has not done this kind of work before. They’re working in silence, occasionally talking. It’s not a service being delivered. It’s a Wednesday afternoon.

This is the unit of the work. Multiply it by eighty mentor pairs across three buildings, every week of the school year.

By the numbers.

200 young people enrolled this year
80 trained volunteer mentors

Three ways to get involved.

Each pathway connects to a person. None of these begins with a form alone.

Donate

A donation runs the buildings. Eighty cents of every dollar goes to programs and staff. Our 990 is on the contact page.

Volunteer

Mentors commit to two years and a four-month onboarding. We accept fewer than half of the applications we receive. Read the brief before applying.

Partner

Foundations, corporate funders, and Philadelphia institutions. Site visits welcomed by appointment.

An afternoon at the building is the best introduction.

By appointment. Wednesdays and Thursdays, three to five. Renee or one of the program directors will walk you through the work as it happens.
