Markos Scheer
Founder, CEO, and Director of Sales
Meet Markos
Seagrove was founded by Markos Scheer, whose life and career have been deeply connected to Southeast Alaska’s working waterfronts.
Markos moved to Prince of Wales Island as a teenager and grew up in rural Southeast Alaska communities including Thorne Bay, Hollis, Klawock, and Ketchikan. Living close to the water fostered a deep respect for the ocean and the people whose livelihoods depend on it.
Early work in seafood processing gave him firsthand insight into Alaska’s seafood economy—experience that would later shape Seagrove’s disciplined, scalable approach to mariculture.
After graduating from Ketchikan High School, Markos earned a Bachelor of Arts from the University of Colorado and a Juris Doctor from the University of Idaho College of Law.
For more than two decades, he practiced law representing seafood, fisheries, and maritime businesses from California to the Bering Sea. That experience provided a rare combination of regulatory fluency, operational insight, and market perspective.
Those lessons helped shape Seagrove into what it is today: a company designed from the ground up to bring scale, reliability, and transparency to Alaska mariculture.
