These committees support and develop positive relationships among members through a variety of social and outreach activities. To build a strong sense of community within the church, it is vital for member interactions to extend beyond its walls. Members are encouraged to participate in one or more of the activities offered throughout the year.

The Social Ministry Committee's activities embody the primary mission of the parish: Reaching Out in Christian Love. The West Allis Relay for Life, sponsored by the American Cancer Society, has become our signature event. Trinity Traveler teams have consistently been top fundraisers for this key cancer-fighting walk/run. Also ongoing is a steady stream of volunteers assisting Guest House and the Florist Avenue Lutheran Church Soup Kitchen, both benefiting area residents. Holy Trinity has partnered with Florist Avenue not only to provide much-needed assistance (financial and more) but also to share ministries, from pulpit exchange to vacation bible school.

The committee's wide range of responsibilities also includes an all-important blood drive for the Red Cross conducted several times per year. West Central Interfaith involves a team of volunteers who ably serve area elderly. The needs of others are also served through a periodic clothing drive. Finally, our global outreach is further reflected in our Lutheran World Relief Coffee Project benefiting small farmers in Latin America.
