Kellie has a passion and energy for the ministry that comes from a deep sense of call. “I have the blessing of spending my life loving and serving Jesus Christ, and loving and serving his people here at RGPC.” She looks forward to the next season in her ministry at RGPC, as together they continue to honor their 88-year history and move into the future with excitement as a missional congregation with a new vision of being a “mission station” in the neighborhood and community, exploring the many possibilities for mission and outreach.

Kate joined the RGPC Youth Ministry Staff in 2013 after a decade of volunteer service at nearby St. Paul’s Presbyterian Church – the congregation in which she was born and raised. Since 2003, she has worked as both a middle school and high school youth advisor where she was responsible for Sunday school and youth group activities, including planning and leading mission trips and retreats.

Kate has also led many Sunday school programs for all ages, planned and led Wednesday Evening fellowship programs, written VBS curriculum, and led Sunday worship as both liturgist and preacher.

After spending a few years as a college softball and basketball coach, Kate soon responded to the call into the seminary and graduated in 2014 with a Doctorate of Ministry Degree from Ecumenical Theological Seminary in Detroit where she currently serves as an adjunct faculty member in the doctoral program.

Kate completed her Commissioned Pastor certification through the Presbytery of Detroit and was commissioned in March 2018.


Sandy grew up in the Chicago area, is a graduate of Moody Bible Institute, and moved to Michigan in 1972. She has two children, 5 grandchildren and 1 great grandchild.

She started accompanying in junior high school. That skill continued to develop throughout high school and college. It became her niche. 

A bout with severe tendonitis required her to put aside the piano. Needing an outlet for the music she tried organ. During five years of private lessons with Dr. Carole Halmekangas, Dr. Huw Lewis and Professor Martin Jean, Sandy found her second love. That unexpected shift prepared and qualified her to serve as organist with this congregation.

RGPC found Sandy in 1997 when the director of Rosedale’s annual winter Broadway musical hired her to play for the production, Kiss Me Kate. Later that year Rosedale hired her as their organist and accompanist for the Chancel Choir.

If you love to sing or want to love singing, if being part of a smaller group calls to you, Chancel Choir could be a great fit. Sandy cherishes the choir members and appreciates their teachability, commitment to each other and to ministering through song. 

For those who already read music and are looking for a different level of involvement than Chancel Choir, adult handbells is led by two very competent energetic musicians. In Fall 2021 a hand chime group was created for adults who wanted to learn to read music.  

Sandy finds joy in creating and coordinating opportunities for singers and instrumentalists to partner in ministry through music. Her Bench Buddy program is a blast. Children and adults in the congregation sign up to sit with her before morning worship and learn about the organ and the piano. The Buddy remains with her through the first part of the service. She loves sharing her passion. It only takes a spark to get a fire going! 

Now retired from two decades as an Executive Administrative Assistant in the auto industry, Sandy devotes herself to her favorite interests: family, music and people. 


Born into the life of this church, Jason was highly involved in the Sunday school, music, and youth group programs. He began playing hand bells at the age of eight and has been playing in some capacity for the past three decades.

After high school graduation, he began teaching the middle school Sunday school class, directing the beginning chime choir, and advising the middle school youth group while he studied secondary education at Eastern Michigan University. Upon college graduation, Jason began working with the high school youth group as a sponsor and a co-leader and eventually served as the interim youth director.

As a member of the congregation, he has served this congregation as a youth and new member mentor, an elder, the co-chair for the Pastoral Nominating Committee (PNC), and in any way Pastor Kellie encourages.
