We proudly continue to grow our heritage, collaborating with our customers to always get better and evolve forward.
Since 1997 when founder John Colson brought together four original companies – PAR, Potelco, Union Power and Trans Tech – Quanta has acquired more than 200 companies. We purposefully retain the unique, de-centralized model that has worked since the beginning.
Through acquisition of companies with long, successful track records, we have expanded our combined heritage to span hundreds of years. That experience, combined with our long-term customer relationships, forms the backbone of who we are and who we will continue to be, supporting and growing with our customers.
