About Our Corporate Symbol

Before dawn on April 19, 1775, Captain John Parker rallied 77 fellow minutemen to face British troops in the first military encounter in America’s War for Independence. Captain Parker and his men, though outnumbered, stood firm in their conviction to secure their freedom. Captain John Parker, our corporate symbol, represents the commitment that Sentry has honored since 1904: Strength, Protection and Vigilance.
