Rebecca Kemper Poos – Pastor

Rev. Rebecca K. Poos began her ministry with us in March, 2009, after having served churches of all shapes and sizes in Vancouver BC and Colorado. She moved to Buena Vista with her husband Clarke and son Rocky (now in his twenties). They enjoy a number of hobbies and passions, all focused on being outdoors. They love nothing more than being in the mountains hiking, snow-shoeing, cross-country skiing, kayaking, exploring Colorado history, and riding bicycles or horses.

Rebecca loves ministry of all kinds. She enjoys encouraging people and churches on their spiritual journey, and has a passion for music and inspiring worship, along with community involvement, and caring for one another in God’s name. She invites you to join in our mission to live out Jesus’ commandments to love our neighbor, ourselves, and to feed, clothe and care for all of creation.

Rebecca can be found in the Church Office or out in the community in a number of places. She welcomes getting to know individuals and families, and can be reached anytime on her cell phone at 719-252-6890 or at

Stints in retail and restaurant serving in Indianapolis, Gatlinburg, TN and Littleton, NH, came next, and finally she made Buena Vista her home in 2008, where she enjoy small town life and friendly people.

Over the years, Nancy has traveled extensively, visiting Japan, Lebanon, and much of the US and Europe. Here in BV, she has worked at the Ark-Valley Humane Society, been a free-lance pet and house sitter, and written for the Chaffee County Times.
