Dennis is the father of two sons and husband to his wife of 29 years. He is very involved in church and many outreach organizations that serve communities locally, nationally and internationally. Dennis started his career playing professional golf for four years; he thoroughly enjoyed every minute of it. However, it was a very difficult career to provide a stable environment for a family, thus Dennis decided to move into the business world. He founded Brown Brothers Asphalt & Concrete in 1995 and grew the organization to become the largest asphalt & concrete maintenance and construction company in Colorado by 2014. He has since sold this company and retired from the business; currently, he is building a commercial waterproofing company. His civic engagements include participation in the following organizations: New Life Church, Compassion International, Denver Rescue Mission, The LA Dream Center, The Colorado Springs Dream Center and Mary's House.
