Gordon Wesener has been in the oxygen business for more than 20 years. He started his career servicing home concentrators with his stepfather and helping him provide oxygen services to retirement homes in the Denver area.
As the need for repair services grew, Gordon and his wife, Brenda, formed American Medical Sales and Repair (AMSR). Initially they focused on repairs, then slowly began building their sales operation.
In late 2009, Crescendo Capital Partners partnered with Gordon and Brenda to grow and develop AMSR into a world-class provider of home respiratory equipment. AMSR is now one of the largest web-based providers of oxygen concentrators.
