Shayne Green was born at Fort Stewart, Georgia, during his father’s service in the United States Army, and was raised in Mayfield, Kentucky. He is a graduate of Murray State University, where he earned a Bachelor of Science in Chemistry, and the University of Alabama, where he earned a Ph.D. in Analytical Chemistry.  With more than 36 years at The Dow Chemical Company, Shayne currently serves as an R&D Fellow and holds two patents. 

Shayne has been married to his wife, Becky, for 43 years. They consider their greatest accomplishment raising their two sons, both of whom are successful, employed Christian conservatives. He is also the proud grandfather of June and Penny Green.

Since 2013, Shayne has served on the board of the Pregnancy Help Center in Lake Jackson. A lifelong conservative, he cast his first presidential vote for Ronald Reagan. Shayne became actively involved in Republican politics in 2008, attending county executive committee meetings and serving as a delegate to precinct, Senate District, and state conventions. Since that time, he has served as a delegate or alternate to every Texas Republican State Convention except one, which he missed to attend his son’s graduation. At the 2024 Texas Republican State Convention, Shayne served as Senate District 17 Chairman and on the National Nominations Committee, for which he was endorsed by President Donald J. Trump.

Shayne became Precinct 30 Chair of the Brazoria County Republican Party after the long-time chair retired and was later appointed Treasurer of the BCRP PAC by former Chairman Yvonne Dewey. In May 2019, Shayne was elected Chairman of the Brazoria County Republican Party following Mrs. Dewey’s resignation. Under his leadership, the BCRP raised and spent a record-breaking $300,000 during the 2020 election cycle, helping elect Republicans to offices throughout Brazoria County.

In addition, Shayne founded the Brazos River Republican Club to expand donor engagement and established the Brazoria County Republican Voter’s Guide, which is mailed to Republican voters across the county. His most recent initiative is the creation of an election integrity task force to help ensure that Brazoria County elections remain fair, transparent, and accurate.
