Michael Marbach, CEO

Michael Marbach is a life long educator and coach. Prior to founding the Christian Outdoor Alliance, he served as Dean of Students and varsity baseball coach at St. Mary’s Hall in San Antonio. His experiences range from teaching, an award winning journalist, to being and accomplished outdoorsman. He currently writes a column under the pen name “Old Tex” in every issue of Texas Trophy Hunter Magazine. Michael’s hunting experience began as a small boy who grew up hunting and fishing with his father and grandfather in the Texas Hill Country and South Texas. He has transitioned to an accomplished guide sharing his knowledge of the outdoors to youth and adults alike, through many COA sponsored hunts and outings. However his most important accomplishment, aside from his family, is the founding of Christian Outdoor Alliance in 2002. His life long goal is to establish an organization that introduces young people to the outdoors and to share his strong faith of our Lord and Savior Jesus Christ. Mike has a B.A. in Journalism from Tarlton State University and an M.A. in Communications from West Texas A & M Universtiy.

Graduated with her BSN from West Texas A&M University in 1996 and has spent most of her nursing career in ICU and School Nursing. Amy grew up in Lubbock living for Christian Summer Camps and is so glad to share many years of youth ministry, Young Life, and camp experience with COA. Married to Michael, the CEO, since 1995, it’s been a blessing (and adventure) to be able to raise their two boys and experience the incredible things God is doing through COA. Her goal is to love and serve God and others and meet them wherever they are in need…. especially with hugs and chocolate chip cookies!
