Tony Reger

Owner | 5 Star Energy

“I enjoy helping builders pass inspections with real-world solutions that are cost effective. Some in this industry will fill out the forms needed to get permits and pass inspections, but their recommendations are not in the owner’s best interests – I’m committed to helping you save money on energy in the long term.”
