The Rev. Michael Dunnington is an “officially” retired priest of the Diocese of Missouri. “Officially,” because he has found that you really can’t stay totally retired.
The Rev. Dunnington was raised in the Roman Catholic church, and early on felt a call to priesthood. After graduating from St. Louis University High School in 1963, he entered the Society of Jesus (Jesuits), where he spent 7 years learning about Ignatian spirituality/prayer, earning both a BA (Philosophy and Letters) degree and an MA (American History) degree from St. Louis University. He went to Belize to teach (part of the Jesuit formation program) at St. John’s College, where he discovered that he didn’t have a calling to priesthood in the Roman Church and returned to lay life.
Since joining the Episcopal Church during a career in industrial marketing and sales (during which time, he earned an MBA degree from SIU-E), the Rev. Dunnington again felt a call to priesthood, and moved through “the process” leading to ordination, and spent three years at Sewanee (University of the South) and earned his Master of Divinity degree. He was ordained a priest in the Diocese of North Carolina in 1997, where he served as Assistant Rector in Burlington, and Rector in Henderson. He returned to St. Louis in 2000, and has served as Priest in Charge at Ascension Episcopal Church (2004-2010), then at All Saints for several years (2010-2019), and finally oversaw the merger of the two parishes.
More recently, he has served as Priest in Charge at St. Barnabas in Florissant (July, 2019 – June, 2020), and served for several months as Interim Priest at St. John’s, Tower Grove. Most recently, the Rev. Dunnington served as Interim Pastor at St. Stephen’s, Ferguson for just over a year (June, 2022 – July, 2023).
In addition to his priestly jobs, the Rev. Dunnington has taught Latin at Chaminade College Prep School, at Parkway West High School, and at the Collegiate School of Medicine and Bioscience in St. Louis.
In his free time, the Rev. Dunnington enjoys playing golf, fishing, grilling/cooking, and model railroading. The Rev. Dunnington and his wife, Leslie, live in St. Louis County.

I have served as deacon at St. Mark’s since my ordination by Bishop George Wayne Smith in November 2014.  I previously served as candidate for the diaconate at Trinity Church in the Central West End and postulant at Emmanuel Church in Webster Groves after graduating from the Episcopal School for Ministry in 2004.  Following my retirement from Ameren Corp., I received a graduate certificate in Non-profit Management and Leadership from UMSL with an internship at BJC Hospice.
My ministry focus is immigration through the Interfaith Committee on Latin America and social services through Isaiah 58 Ministries.  I have spent many years on non-profit boards addressing low-income housing, children’s advocacy, hunger ministry, and the YMCA of Greater St. Louis.
I continue to be inspired for outreach ministry by my wife Gayle who died in 2010.  I have two adult daughters in the St. Louis area and two grandchildren who call me by the coolest grandpa name ever – Big Dude.
