He worked as a Business and Information Technology teacher at Louisa County High School in Mineral, Virginia and Falls Church High School in Falls Church, Virginia. Business and Technology allowed him to gain experience in a variety of activities and subjects. He has taught courses such as computer programming, law, management, accounting, and information systems. He has served as department chair, website curator, IT support staffer, and study hall/detention coordinator. He was also an FBLA advisor. In 2009 he graduated from the University of Dayton with an MS in Educational Leadership. Two months after graduating, he and his family uprooted and moved to Germany for the next six years! During this time he completed his Ohio professional principal licensing at Ramstein High School, Ramstein Air Base, Germany. During that time he was a stay-at-home dad. Living in Europe allowed him the opportunities to travel to dozens of countries, as well as volunteer at the preschool and elementary schools in addition to interning at Ramstein High. In 2015, he and his family moved to Colorado for their next adventure. Since moving to Colorado, he's earned his initial K-12 principal license as well as his 7-12 professional teaching license with endorsements in business, technology and instructional technology. He looks forward to supporting and teaching the staff and students of Pine Creek High School and is excited to be back in the content area where it all began for him!
