Clergy and Staff


The Rev. Mike Stone

Mike Stone, Rector (

Mike found and was found in the Episcopal Church after being nourished by myriad stops along the way: ordained Southern Baptist ministry, participation in almost every mainline Christian denomination and study in five differently confessional seminaries, teaching high school math, coaching wrestling, fishing for salmon in Alaska, and being built up by love after having puffed himself up with knowledge. He is the grateful spouse of Rebecca and the proud father of two children, Daniel and Emory, and caretaker of his canine associate, Maggie the goldendoodle.  He eccentrically makes soap, mills grain, produces stained glass windows and custom cabinetry, plays the guitar, shops at livestock auctions, and wants to know more about, well everything, especially you!


Garmon Ashby, Music Director   (
Garmon grew up in South Africa, the son of Anglican missionary parents. After serving as Director of Music at the Diocesan College, Cape Town, and Director of the Cape Town Symphony Chorus for a number of years, he accepted a scholarship to study a Masters in Choral Conducting at Yale. After his studies there he was called to be Music Director at a large Episcopal parish in Tucson, Arizona, before moving to Houston, where he is Chair of the Performing Arts Department at the Episcopal High School. He was appointed Director of Music at St. Thomas in 2011.


Miriam Griffis, Organist

Miriam Griffis has over 60 years of experience as a church organist, and has been the organist here at St. Thomas for over 10 years. In that time she has become a well-beloved part of our community. Everyone knows and loves Miriam. Miriam has a Bachelor of Music from Baylor University and a  Masters of Sacred Music from Union Theological Seminary, where she was acquainted with both Paul Tillich and Reinhold Niebuhr.
