Staff and Leadership

Churches form leaders and reliable followers everyday. It's how we contribute to building the kingdom in the world.

The Rector facilitates worship, builds a vision for the parish, and teaches the faith in body and spirit.

The Wardens, co-presidents, help implement the vision, oversee the physical plant, and help ensure financial health of the church.
The Vestry is an elected body who serves as the board of directors. They implement the vision of the parish, with God's help.

  • The Rev. Dr. Gawain de Leeuw, OA

    A lifelong Yankee, I was born and raised in Western New York (Go Bills! Orange!)  to a poet and a teacher. Ordained in 1996, I arrived at St. Bartholomew's in 2001, after serving congregations in Seattle, Korea and White Plains. I was raised in a non-religious family with roots in Roman Catholicism, Unitarianism, the Baptist tradition, and Hinduism, but I had a mystical experience as a teenager during a sung evensong.

    My vision is a spiritually vibrant and joyful congregation where people learn how to serve in the world with thoughtfulness and courage. As a member of the Order of the Ascension, a dispersed Christian Community, I seek to foster prayerful, reflective, and healthy spiritual practices that can form nurturing, generous, and prayerful people in a tough world.

    I was graduated from Oberlin College with a first degree in philosophy, with graduate education from The Divinity School of the University of Chicago, General Theological Seminary, and Seabury-Western, an Episcopal seminary.

    In addition to my regular work serving St. Barts, I serve on the boards of Meals on Wheels, the Housing Action Council, and Planned Parenthood. In 2011, I founded Westchester United with three Rabbis and a priest. It's no joke.

    I have a few minor credentials in food and wine, and have performed stand -up at several clubs. Once in a while I attempt a new joke. If you want to hear one, you'll have to visit. I root for Dutch Football, Tottenham, the Yankees, and occasionally the Cavs when not playing Sacramento.

    I look forward to meeting you.

  • Marsha Calhoun, Vestry

    Born in Virginia, my family moved to York, PA when I was small but returned when I was a teen-ager. I was graduated with a degree in speech therapy from a cooperative program at Mary Washington College and the University of Virginia. Later, I became interested in social work and mental health and attended graduate school at Virginia Commonwealth University in Richmond.


    My husband, Chip, and I had known each other since high school and reconnected while he was in law school at UVA. We married and moved to the Big Apple. Ten years later we moved to White Plains for peace and quiet! We now have one son, John, age 22 who is the love of our lives and keeps us eternally young.

    I retired from U.S. Pretrial Services a few years ago. Chip and I both enjoy reading, movies, theatre, history and travel. We spend a lot of time at our cabin in WV, watching the wildlife and reading. 

    We have been attending St. Bart's for 20 years. My husband served on the vestry in the past and now it's my turn. I've also volunteered in the office and attended the Women's Group where we spend a lot of time laughing, supporting each other and working on various church-related projects. 

    I was raised in the Episcopal Church and vividly recall its importance to my family. My parents met their closest friends  through the church. Chip and I have had the same experience at St. Bart's where we have met some of the finest people we know. Father Gawain and our St. Bart's family have helped us celebrate some of life's most joyous moments and given us strength and love to endure the difficult times.

    We are privileged to be part of this spiritual community.

  • Mark Douglas, Vestry

    I'm a lifelong resident of the Greenburgh/White Plains area. My passions are my family, my beautiful wife Jennifer of 35 years and my lovely daughter Leigh, as well as a love for all things Music. I came to Saint Barts after meeting Fr. Gawain, at a couple of meet


    Saint Barts is a warm and welcoming place. The progressive, open

    atmosphere, along with it's traditions is what keeps me coming back. The diversity of people, ideas and ministries shows that when people come together anything is possible. I brought the Acoustic Café to Saint Barts as a way of giving back to the mission of this wonderful church. I am happy to serve on the vestry.

  • Kimberley Ware, Vestry

    I'm a self employed computer tech and trainer, who has a penchant for getting involved. I worked several years in the retail and restaurant industries, as well as a few years as an active realtor. I'm currently a Girl Scout Troop leader, the Bylaws chairperson for my school district's PTSA, a class parent, and I teach two evening classes a month at our local Board of Realtors. In my spare time I love to cook. Keeping busy has never been a problem for me. When Father Gawain approached me with regard to serving on the Vestry, I took it as an opportunity to give back to this welcoming church that has become the spiritual home to my husband, my daughters, and me.
