Dennis was born in Jerseyville and grew up in Columbia, where he graduated from Quincy College. He started his teaching career after college, but soon returned to obtain his Master’s Degree in music education at the University of Illinois. After his graduation, he returned to teaching in Springfield, where he met the love of his life Denise. The two met through their mutual love of music, a love that was nurtured throughout their lives together.

Once married, the two moved to St. Charles, Ill., and began the journey of starting a family with their first child Jesse. The family unit was completed just five years later with twin boys Brett and Gene. After 37 years of teaching in the St. Charles area, Dennis retired and relocated with Denise to Stillwater, Minn. in order to be by their grandchildren.
