Founded in 1996 by Kevin O’Neill, Pittsburgh-based Square One Medical equips workplaces and community organizations with AEDs while providing emergency-response training and AED program management. The company grew from a business-to-business lead-generation firm into a major regional ZOLL AED distributor, with CPR instructors who train hundreds of individuals and businesses each year. Its support extends beyond the purchase, helping customers keep devices ready and employees prepared through implementation, compliance, and hands-on instruction.
