I was raised in Webster City, Iowa and graduated from high school there in 1981. I am a graduate of the DMACC, Heating, Air Conditioning and Refrigeration Program. 

My heating and cooling career includes commercial refrigeration with Perishable Distributors of Iowa and A. J. Allen Mechanical.  My residential experience was gained working for A/C Contractors of Des Moines.

I joined DMACC in January of 2008, which has given me the opportunity to share my knowledge of the HVAC industry while incorporating many other life experiences from the past 25 years.  I received my BA from Grandview University in 2015.  I believe strongly in education and continue to take classes and industry training.

I have been married to my wife Diane, since 1985. We have 3 children and we live in Ankeny. Our main hobby is camping. We like to travel out of state with our travel trailer, but also like to take short trips to campgrounds in Iowa.
