William is Panamanian and comes from Piñas Bay in the Darien province. His father ran the fishing store in Puerto Piñas and so his life has revolved around fishing since he was a baby. He has worked with sports fishing boats since 2002 and worked for the famous Tropic Star Lodge under the general manager of Panama Yacht and Fishing Charters, Hennie Marais, who was previously general manager at Tropic Star. Since Tropic Star he has been working on privately owned fishing yachts.
