Mr. David Swain

My name is David "Trey" Swain.  I moved to San Marcos in 2001 after graduating from Canyon High School in New Braunfels.  I met my wife while attending Texas State University and we now have 2 children that both attend SMCISD schools.  I have been in education for 6 years, the last 3 being at Mendez Elemetary.  After school and on weekends, I coach soccer, baseball, and softball here in San Marcos.  I am also on the City of San Marcos Commission for Children and Youth.  I enjoy going to work everyday being a role model for the children of this community.  I am excited about the future of San Marcos and the part that SMCISD is playing!
