“Helping people get out on the water and explore new places, enjoy their favorite coves, and truly reset is my passion. Growing up on The River, I’ve found there truly nothing like a life on the water. I hope to help as many people have a positive experience on the water as possible, and that all starts with the boat you’ll be exploring on.”

Having grown up on the St. Lawrence River aboard his family’s 43’ Tiara docked at the Thousand Island Club, he developed a lifelong passion for boating and life on the water.
