Dennis joined the United States Air Force upon his graduation from Mansfield Jr. Sr. High School, class of 1988. After basic training, he went on to technical school to become Security Police.

Dennis was employed by the Okaloosa County Sheriff’s Office in 2009 and retired in 2019. Towards the end of his career with OCSO, he was a school resource officer and found it the most rewarding part of his service.
He was a faithful and loving member of Our Savior Evangelical Lutheran Church, where he served as a deacon. He was also a proud member of Combat Vets Motorcycle Association (CVMA).
Dennis gave his absolute all in every endeavor whether peddling the newspaper, working on the farm, McDonald’s, playing baseball and softball, riding motorcycles, etc. His life of sacrifice and service extended to every possible facet of his life. Anyone who has met Dennis knows he always served with a smile no matter the circumstance.
