History
Peitsa Hirvonen began working in the building trades with his father. Both originally from Finland carry on the tradition of skilled craftmanship and commitment to quality. In the 1980's he learned electrical from local contractors and established SESCO Electrical in 1992, originally seismic and electrical systems and by the late 1990's the business was solar and electrical as it continues today. SESCO incorporated in 2005 and added Regina Gilligan, Peitsa's wife as an owner. Now in 2020 Peitsa and Regina are ready for the retired life and have sold SESCO Electrical to two of SESCO's employees, Virginia Gonzalez and Hugo Lopez.
