What The Sisters of the Society of Our Lady of the Most Holy Trinity does

The Sisters of the Society of Our Lady of the Most Holy Trinity (SOLT) is a Catholic society of apostolic life of diocesan right, founded in 1958 by Fr. James Flanagan and headquartered in Corpus Christi, Texas. The organization operates as an international missionary community composed of three branches: priests and brothers, sisters, and laypeople, who serve together in ecclesial family teams. SOLT operates across 8 countries — the United States, Mexico, Belize, Guatemala, Philippines, Papua New Guinea, Thailand, and Australia — providing education (Montessori and traditional Catholic schools), evangelization, pastoral ministry, retreats, healthcare, and drug rehabilitation services, with a particular focus on areas of deepest apostolic need.

SOLT's service offerings are delivered through parish ministries, educational institutions, retreat centers, and residential care facilities, including Santa Maria del Mexicano in Mexico (serving 180 children and 25 elderly) and catechism programs reaching 600 students in Detroit. The organization is led by elected servant leaders: Fr. Peter Marsalek as General Priest Servant, Sr. Mary Aloysius of Jesus Kim as General Sister Servant, and Rosalie Buergler as General Lay Servant, all elected at the 8th Ordinary General Chapter in July 2023. SOLT reaches stakeholders through its website (solt.net), social media channels, the Gray Robes Magazine, EWTN media appearances, and the Liturgy Prep video series.

The organization's revenue model is based on donations, parish contributions, and charitable giving. SOLT accepts donations through its website and runs vocational discernment programs (Come & See weekends, year-long missionary volunteer placements) where volunteers cover their own travel costs. The community is governed under the ecclesiastical authority of Bishop William Michael Mulvey of the Diocese of Corpus Christi, with approximately 110 professed sisters serving across the network.
