About our Company
Mastor, located in the Westport area of Metro St. Louis, services clients within 100 miles of the St. Louis Arch and Nationwide through an installing dealer network. Everyone, from our certified sales and technical staff to our dispatch and customer support is helpful, courteous, and knowledgeable. We are a team of professionals, dedicated to treating customers and prospective clients with respect, honesty, and integrity. We are extremely proud that our employees average just under 15 years with the company. That is a testament to our working environment and our reputation in the industry.
Mastor opened its doors as Mastor Telecom Equipment in early 1991. Selling primarily refurbished telecom equipment to installers, Mastor quickly grew in both size and reputation as an excellent source for quality refurbished equipment. Since early 2000, Mastor has provided clients in the St. Louis area and surrounding communities with excellent products and service. In 2008-2009, Mastor, working with Toshiba’s National Account Team, successfully sold, configured and shipped over 15,000 telephone systems for a large financial firm with offices all over the country. This sale was the largest single project in the history of Toshiba’s telecom division. Since the closure of Toshiba’s North American Telecom Division in 2016, and with the increasing popularity of VoIP technology and Unified Communications, we have refocused our product offerings. We have added additional products and services to our portfolio including NUSO Cloud PBX and SIP Trunking, Epygi VoIP Premise based systems, Security Cameras and NVR’s, and WiFi routers and wireless access points.
