Dennis's journey began in the Seminary, where his path took a serendipitous turn upon meeting the love of his life, Mary Kay. Also during this time, he spent 6 years in the Army National Guard and was very proud of his service to our country. Dennis found his true calling in the pastoral life of a dairy farmer. His connection to the land and his cattle was more than a job; it was a testament to his character and his love for nature's gifts. In addition to farming, later in life Dennis found a home in sales. He worked with various local lumber companies, where his honesty and personable nature made him a favorite among customers and colleagues alike. He had a notorious sweet tooth, with a particular fondness for Burger King's 'cinna-minis,' which brought him an almost childlike joy. His enthusiasm for these small delights was infectious and a reminder to all who knew him of the importance of savoring life's sweet moments. He will be remembered with love and admiration by all who were fortunate enough to know him.
