St. Mary's is a growing parish, with about fifty active members and one-hundred twenty-five persons on the membership roster. An influx of both youth and families has created an evenly balanced "cross-generational" congregation. Youth ministry is one of St. Mary's largest potential growth areas, given the sixty thousand students attending local colleges.
Being the only Episcopal Church in Utah County, members come not only from Provo, but several come from forty or more miles away. Parishioners range from a capable group of "new" (less than one year) members to about one-third long-time (over ten years) members, allowing the parish to provide a variety of services, events, and programs with devoted leaders regularly stepping forward. Although members of St. Mary's are part of a religious minority in Utah, they are very welcome as prayerful Christians in the community, and participate in numerous multi-denominational programs and services.
Members of the congregation are involved in their community in many ways; some serve on the Utah Valley Ministerial Coalition, Board of Directors of Food and Care Coalition, Utah County Board of Health, and various diocesan committees. Parishioners work in the community as professors and students at BYU and Utah Valley State College, healthcare workers, construction and utility workers, homemakers, and in many other capacities.
Approximately one quarter of parishioners were raised in Utah, and on average, members have lived in Utah County nine to ten years. Almost half have extended family in Utah, and most work in Utah County as well.
Nine out of ten parishioners perceive the overall well-being of the parish to be in the good to very good range.
