Yvi Martin, Lead Pastor

Rev. Yvi Martin comes to Platte Woods UMC after 11 years of ministry in the Missouri Annual Conference, serving churches first in Springfield (King’s Way UMC), then St. Louis (The Gathering UMC). First called to ministry at the age of 15, Yvi served as a missionary for the Free Methodist Church in both the Philippines and Mozambique before discerning a call to pastoral ministry and beginning that journey at Candler School of Theology at Emory University. While pieces of her heart remain in every place she has served, she eagerly anticipates sharing gifts of teaching, writing, preaching, music and hospitality with the wonderful community of Platte Woods UMC.


Along for the adventure is husband, Scott Giffen, who works as VP of Advancement for Greenville University, but more importantly brings the gifts of humor, leadership, music and a deep faith to this new church community. Their two sons, Ezekiel (8) and Lazarus (4) come with all the energy, creativity, spunk and strong wills that one might expect from preacher’s kids! They will quickly make every other parent of small children who act out in church feel completely normal and ok. And they will, no doubt, make you laugh.

Jess Horsley, Associate Pastor

Passionate about building relationships, celebrating people’s unique stories, and helping people discover their God-given gifts and abilities, Rev. Jess Horsley comes to Platte Woods UMC having served in the St. Louis area in full-time ministry since 2009. A lifelong United Methodist raised in rural Iowa by a nurse mother and a farming father, Pastor Jess discerned a call to ordained ministry after years of eclectic jobs: high school English teacher, professional film critic, action figure & video game reviewer, and machine gunner in the United States Marine Corps.


Pastor Jess enjoys watching movies (especially sci-fi and horror!), reading comics (make mine Marvel!), collecting sneakers, getting tattooed and encouraging and empowering others to unleash their love, presence, power and knowledge to change their lives – and the lives of others – for the better!


Married for 20 years to his high school sweetheart Shelly, who works for Sisters Floral Design Studio in St. Louis, Jess and Shelly have the pleasure of parenting Amelia (12), a musician and empathetic soul; and Warren (8), a dancer who loves video games. Together, their family cares for Samson, a rescue cat who has a love/hate relationship with the outdoors.
