Mayor Denman recently retired as Vice President and Chief Operating Officer of Riviana Foods, Specialty Brands Division. Riviana Foods is the No. 1 rice and No. 2 pasta company in the North America. During his career he served as Chairman of the USA Rice Federation, a 2500 member industry organization composed of all US rice farmers, rice millers, marketers, and seedsmen in the rice producing states of Arkansas, Texas, Louisiana, California, Mississippi, Florida and Missouri. He also served as Chairman of the US Rice Millers Association prior to becoming Chairman of the USA Rice Federation.
Mayor Denman is a 34-year resident of Nassau Bay serving as a City Councilman for 9 years, Economic Development Committee for 13 years, Dredging Sub-Committee for 12 years (two of them as chairman), Planning Commission for 2 years, Fire Department Subcommittee for 6 years, and the Hotel Tax Appropriations Subcommittee for 13 years. He also served multiple years as Beautification Day Co-chairman. He currently serves as a board member of the Bay Area Houston Convention & Visitors Bureau and was recently elected by the Harris County Mayors and Council Association to the Greater Harris County 9-1-1 Emergency Network Board of Managers.
Mayor Denman counts as one of his greatest accomplishments the initiation of the annual peninsula cleanup day that he started in 1996. Beginning in 2004, the event was coordinated with Clear Creek Environmental Foundation (CCEF) that annually sponsors a cleanup day for most of the Clear Creek area, including the City's peninsula.
While on City Council, Mayor Denman was successful in getting Council to agree to open up the peninsula to visitors, starting with a few days a week, and eventually moving to seven days a week. He was also successful in starting the City’s first curbside recycling program in 2011. It has become one of the most popular programs in Nassau Bay, in regards to citizen participation.
Other recent major accomplishments include a new fire station (opened June 2018), new streets for Harbour, Basilan and San Sebastian, as well as a new David Braun Park parking lot and expanded jogging sidewalk around the park. Those new streets, park parking lot, and sidewalks, were primarily funded by Harris County, thanks to the cooperation of Harris County Pct. 2 Commissioner Jack Morman.
His areas of focus include infrastructure repairs, economic development, and city beautification (especially all waterfront areas). He is most proud of his association and co-founding of the Clear Lake Area Mayors group that meets four to five times a year to discuss cooperative agreements and other area issues that impact our cities, sharing helpful information and suggestions on what does and does not work.
