Most recently, he served as the Athletic Director at Ralston Valley High School. As a Colorado native, he started as a student in Jeffco in 1980 and was a Pomona High School graduate in 1994. He earned his Bachelor of Science with a specialization in sports marketing from Baker University in Baldwin City, Kansas, where he met his wife, Theresa. Shortly after graduation, the two moved back to Colorado, the greatest state in the country where they have raised three kids, who all attend Jefferson Academy. When not attending high school athletic events, he enjoys golfing, mountain biking, playing flag football and softball and has even picked up lacrosse in his old age. With a strong connection to the school community, he hopes to diligently continue to build upon the successes both on and off the field/court/course for our student-athletes.
