About Us

Electrical Wizardry, inc. was formally established in 2004 by John Siemiarowski. John started in the electrical industry in 1964.

"We don't see problems, just opportunities to show how good we are."

Electrical Wizardry is operated by John Siemiarowski. The team includes three other electricians, as well as two apprentices and Kim Miller. Kim manages our office, while scheduling the team for appointments throughout the Philadelphia area. While most electricians do not have the length of time and experience that John does, all of the employees at Electrical Wizardry have access to the knowledge base that has been accumulated over many years. A culture of learning is a core value for EW. This is important because things in the electrical industry are constantly changing, such as the revisions to the national electrical code happening every three years or the rapid development of solid state lighting (LED lighting). We pride ourselves in showing respect to all our clients, as well as their houses, businesses, and places of worship where we make magic happen.
