Duckweed: The Next Super-Resource

By Bronson Fong

Mentor

• Glenn Sebring, a self-made entrepreneur , has lived in the south his entire life. While he was born in Picayune in the year 1971, Mr. Sebring has spent the majority of his life in Pearl River, Louisiana. From ages 12-19, Mr. Sebring held a job at Levis Chevrolet, balancing school and work. He graduated from Pearl River High School in 1990 and went on to go to SouthEastern Louisiana University. There, he obtained a bachelor in management and a minor finance. To finance his education, he took up hay farming in 1992, capitalizing on the hole in the market for “luxury” grain. After finishing college, he promptly opened up his own construction business, building buildings such as the Home Depot on Northshore Blvd. As his construction business grew, so did his hay business. Before he knew it, he had contracts from horse tracks all over the nation and some parts of Canada. He currently supplies the hay for Louisiana Horse tracks, Fairgrounds and Evangeline Downs. He married his wife Rosie in 1999 and the two had their first child, Breanna, in 2004. While he remains busy, Mr. Sebring is always looking to foster new startups and aid in any way possible.
