About this church
St. Sebastian Catholic Church celebrates Sunday Mass at 8:00 a.m., 10:30 a.m., and 6:00 p.m. at 5400 West Washington Boulevard in Milwaukee. Monday Mass is at 8:30, and Wednesday school Mass begins at 8:15 while classes are in session or 8:30 on other days. Saturday morning Mass, Reconciliation, and Adoration alternate between St. Sebastian on first, third, and fifth Saturdays and St. Catherine on second and fourth Saturdays.
The parish’s mission is to proclaim Christ and grow believers through sacramental life in an inclusive, responsive Catholic community. Its history began with a Mass celebrated in a storefront at Fifty-Fifth and Vliet on August 15, 1911; the parish school opened the next year with 32 students and three School Sisters of Saint Francis. That school remains part of a broader campus serving Milwaukee’s Washington Heights and nearby Wauwatosa. On Welcome Sunday, the first Sunday each month, newcomers can meet a parish representative in the multipurpose room after any Mass. Visitors should distinguish St. Sebastian’s schedule from partner-parish services at St. Catherine, especially for weekday and rotating Saturday liturgies.
