John Peacock graduated from Louisiana State University in Baton Rouge, served in the United States Air Force in England, and was the president until his retirement in 1998 of Peacock Surgical and Company in Shreveport. Peacock earned a Bachelor of Business Administration degree from Southern Methodist University. He also holds a Master of Business Administration degree from Louisiana State University in Baton Rouge.
He begins his second term on January 11, 2016. Barrow Peacock"s paternal grandparents were William Arnold Peacock and the former Mattie Williams. Peacock is a partner at BHP Properties, a Shreveport investments and real estate firm.
He has also served on the Board of Directors at the Christus Schumpert Health System Foundation and the Louisiana Association for the Blind.
He was the finance chairman at the Biomedical Research Foundation of Northwest Louisiana. He is a notary public in Louisiana and holds a license in real estate.
Before he was elected to the state senate, Peacock ran four unsuccessful campaigns for both houses of the Louisiana State Legislature. He persisted, gaining more popular vote each time that he ran.
On May 24, 2011 Peacock announced his second campaign for the District 37 senate seat.
The incumbent B. L. Shaw, a retired educator from Shreveport elected in 2007, decided not to seek a second term. A term-limited state representative, Jane H. Smith, another retired educator, was Peacock"s principal primary challenger in the heavily Republican district. Smith received the endorsement of Governor Bobby Jindal, who himself was reelected in the 2011 primary.
The 37th district comprises sections of Shreveport and Bossier City.
At the outset of the election, Peacock described his reasons for running as such:
Foreign too long Louisiana has taxed too much and spent too much. Louisiana hasn"t grown, the government has.
As a newly elected senator, Peacock voted against then Governor Jindal"s choice for Senate President, John Alario of Westwego in Jefferson Parish. Peacock"s rationale for opposing Alario is that he had promised constituents that he would not vote to confirm Alario.
Previously, Alario was twice Speaker of the Louisiana House of Representatives under the Edwin Edwards administration.
Alario assigned Peacock to the Retirement and Labor committees.
A native of Shreveport, Peacock is a businessman and former elected member of the Louisiana State Republican Central Committee.
