While Performance Services has grown dramatically since 1998, when we began as a company of one, our Guiding Principles have endured: A commitment to People, Excellence, Service, Growth, and Stewardship. For 25 years, we have provided exceptional value in the design and construction of high-performance buildings and systems with a 100% client satisfaction guarantee. We extend our sincere gratitude to our employees, partners, and clients who have enabled us to grow and thrive.
