About Us

Formed October 1^st of 2018, Gen-Mark is an electrical manufacturer’s rep firm serving Western Pennsylvania and West Virginia.  This merger of Gemco Sales (1969) and Renmark (2003) created a sales team that has served our local markets for a combined 350 years.  Long-term local knowledge of construction, industrial, power quality and power electronics customers uniquely position Gen-Mark to service the demands of the electrical industry.  With 8 inside sales and support associates and 9 outside sales representatives, our staff spans two generations and is focused on delivering unrelenting customer service.  We have two engineers on staff to provide design assistance, training, commissioning and start-up services. Our goal is to be the best and first choice for distributors, contractors, engineers and end users. In December of 2018, we occupied a new state-of-the art office and training center in Wexford, PA.
