Missio is a Catholic apostolate that seeks to proclaim Christ to all peoples through living a missionary life and intentional discipleship.

Missio is a Catholic apostolate founded by Sean Crepin to inspire, form, and send missionary disciples rooted in the love of Christ and the teaching of the Church. Drawing from over a decade of pastoral leadership, theological formation, and missionary service across the Caribbean and the United States, Missio seeks to cultivate authentic encounters with Christ through catechesis, community outreach, retreats, and missionary engagement. Guided by the Church's call to evangelization, Missio exists to empower the faithful, especially youth and young adults, to live out their vocation to holiness and mission in today’s world.
