Shaeffer Electric is a third generation, family owned and operated electrical construction company. William started the company in 1908 and built it through constant attention to detail, customer service, and innovation. We are proud to have survived two world wars, the Great Depression, and countless other challenges.

Today, the company has five principal owners: bothers Jerry, Paul, and Bernie Shaeffer, cousin Bill Shaeffer, and the newest owner Kevin Pinkerton. Collectively, all five have over 175 years of estimating, project management, and electrical construction experience in the Philadelphia marketplace.
