About Us
Western Nevada Supply Company (WNS), was founded in 1964 by Jack Reviglio and Bill Higgins, and is still owned and operated by the Reviglio family. WNS is a community involved, customer service oriented company, dedicated to improving the quality of life in Northern Nevada.
On March 1, 2003 WNS acquired Conservation Mechanical & Air, Inc. (CMAI), a 16 year old manufacturers representative firm, and created WN Mechanical Sales, and in 2011 WN Mechanical Sales and Nevada Mechanical Systems merged to create WN Mechanical Systems. This partnership brought together the Mechanical engineering expertise of Trevor Benbow, and strength of WN Mechanical Sales / Western Nevada Supply for a more focused and value added product. WN Mechanical Systems brings together experienced individuals from several arenas to create Northern Nevada's largest and most experienced manufacturers representative and controls contracting firm.
