Clergy and Staff

Pastor, Rev. Dr. Mary Kay Totty

Since July 2009, Dr. Totty has served as Dumbarton's appointed pastor. Her passions for ministry include creative worship design, preaching, social justice advocacy, and community-building. She has been found serving communion on the steps of the Supreme Court in celebration of the landmark decision in favor of marriage equality, blessing bicycles along the C&O Canal, marching for an end to gun violence, in costume for the intergenerational Halloween party, leading progressive theology studies, and singing with the Dumbarton choir. Mary Kay believes that God's steadfast, abiding presence surrounds each and everyone; and in each moment God genlty lures us toward words and actions which help build the kin-dom of God.

Dr. Totty earned her Doctorate of Ministry in Art and Theology at Wesley Theological Seminary in May 2015; her Master of Divinity at Brite Divinity School, Texas Christian University in 1989l and her Bachelor of Arts degree in Religious Studies and English Literature at Louisiana State University in 1985. For her doctoral project, Mary Kay created a study/worship/sermon series based on T.S. Eliot's "Four Quartets." She led the series at Dumbarton and recruited three colleagues to lead the series in their churches.

Mary Kay enjoys dinner parties, good coffee with friends, hanging out with her dog, reading, museums, and creativity. She delights in making art from home-made cards to watercolor paintings, from collage and assemblage pieces to upcycled vintage jewelry that she embellishes with tatting. Mary Kay really does believe that the world needs more lace.

Youth and Children's Minister, Yvonne Agduyeng

As your new Youth & Children's Minister, I first want to say how excited I am to get to know and spend time with the Dumbarton community! You're probably wondering, "Who is this Yvonne?" Well, I was born in the Philippines and immigrated with my family to Seattle, WA when I was six years old. I grew up attending Seattle First UMC and participating in an American-Filipino youth camp called Christmas Institute as a camper and then a counselor throughout college. Since graduating, I have continued to be a part of the Christmas Institute as the Camp Director !

 I am currently a second year student at Wesley Theological Seminary pursuing a Master of Divinity degree. I am also an intern at the General Board of Church and Society. I hail from the land of coffee, so yes, you will most likely see me with coffee in one hand most Sunday mornings. I love to play tennis and am always looking for a hitting partner, so let me know if you play! As we transition out of summer and into a new season, I pray that this upcoming year be filled with fellowship, laughter, learning and much more at Dumbarton UMC. I hope to get to know all of you more so please don't hesitate to say hello!
