He continues to receive training from outdoor power equipment industry professionals through the EETC, where he has served on the 2-Stroke and 4-Stroke Certification Committees and currently serves on the EETC Education Committee.

Active in SkillsUSA, Mr. Senn is a Certified SkillsUSA State Director and was awarded the SkillsUSA Outstanding Career and Technical Educator Award. He is also a local SkillsUSA club Advisor, and his students have competed at National Leadership and Skills Conference in each of the last 22 years.
