Who is Arlen Benny Cenac, Jr.?

Arlen “Benny” Cenac, Jr. is Lousiana businessman and an entrepreneur with a global reach. Benny has owned Main Iron Works since July of 2015 and is a third-generation owner of Cenac Marine Services.

He has led Cenac Marine Services through several industry hardships by focusing on the values set before him by his grandfather and founder, Jock Cenac.  Benny’s maternal grandfather, Horace “Jack” Guidry founded Main Iron Works in 1947.  Since his tenure at Main Iron Works, he has applied the same values set before him by both of his grandfathers to lead the company into the next generation.  These values, combined with a focus on customer service, reliability, and quality are what separates Main Iron Works from the competition and allows them to service customers across the country. 


Benny takes pride in continuing the legacy of his grandfathers and continues to focus on operating both businesses as family by concentrating on a constant commitment to employee satisfaction and great company morale.
