Treasurer, Chris Barker

As a cradle Episcopalian, I grew up on the Southwest side of Houston, and attended Church of the Epiphany with my parents.  About 40 years ago, I moved to the Heights, subsequently married, and had a daughter who I wanted to raise with the same spiritual tradition I was provided, so we joined St. Andrew’s.  I became very active in the youth activities as Christy progressed through school.

My education background was in accounting, but practicing that didn’t give me the people exposure I wanted, so my professional career led me in another direction, and for the past 30 years have served as an HR Manager for an international engineering firm.  I have served twice on the St. Andrew’s Vestry, and have been our Treasurer since 2009.  I consider my Treasurer position at St. Andrew’s as my “fun” career, and I thoroughly enjoy doing what I’m called to do for our parish.

Organist & Choirmaster, John Kirk

From a young age, music was a large part of John’s life—music was always playing at home and in the car, a year of obligatory piano lessons, singing in musicals and choir in high school, playing double bass in jazz band, playing in a band throughout high school and college, and always vibrant congregational singing at the Lutheran church in which he grew up. Like his musical activities, his tastes were diverse: Led Zeppelin, Radiohead, The Smashing Pumpkins, J.S. Bach, Tchaikovsky, and the Star Wars soundtrack were among his favorites. 

John attended Capital University, studying both Religion and Double Bass, and while there, the university installed a new organ. The educational seminars about the organ piqued John’s interest, and the series of inaugural concerts exposed him to the depth and power of the organ’s repertoire. He started taking organ lessons and soon found himself spending more and more time at the organ console and less time behind the bass, and so he added yet another musical interest with no clear vision of how things might come together. 

After moving to Houston following college, John began studying organ, voice, and church music with Robert Brewer and assisting in the music program at the Episcopal Church of the Epiphany in Houston as a Choir/Organ Scholar. Here, John was finally able to connect all the musical threads of his life in church music by immersing himself in strong music program that presented a wide variety of material and was composed of committed, hard-working volunteer singers under a passionate and energetic director. In church music, John found the energy and conviction of rock music combined with the craftsmanship and interest of classical music, all within a context that focused on something bigger than music itself.

Following his work at Epiphany, John was Music Director of Holy Trinity Episcopal Church in Dickinson, Texas and Organ Intern at St. Philip Presbyterian in Houston, Texas. He is presently Organist & Choirmaster of St. Andrew’s Episcopal Church in Houston and is pursuing a Master’s degree in Organ Performance from the University of Houston’s Moores School of Music, where he studies with Robert Bates and studied improvisation and service playing with Sigurd Øgaard.

Years after, I moved to Florida where I became a US citizen and had my own landscaping business. Currently I live in Houston where I got certified as an electrician.
