Cottle began his coaching career as a graduate assistant at Salisbury and then spent three years as the head coach at the Severn School, where he compiled a 26–9 record.
Severn has received praise for their nationally acclaimed sailing team, which held the title of the number one high school sailing team in the nation in 2008, coached that year by Thomas Sitzmann and now by Scott Steele, 1984 Olympic Silver Medalist in sailboarding.
