John W. Tarr, P.E.


Early in John’s career he developed a passion for constructing buildings and seeing them come together from a hands-on perspective. This passion led John into the field of electrical engineering. John’s expertise is broad with over 25 years of experience in electrical design. He has designed systems that include interior and exterior lighting, power distribution, emergency power (life-safety and optional power), fire protection, security, and communications systems. His designs incorporate energy efficiency as well as appropriate, functional use of space, and code compliance.

As a Principal, John leads our engineering department and can always be counted on to make decisions that prioritize our clients success and builds relationships that last well beyond a job done right.
