Tom Thayer

CEO

Thank you for coming to our website. It is my hope that when you put your mouse down and decide to take action for your facility needs, that we’ve given you enough information for you to make PSI your first call for your specialty contracting needs.

I formed PSI to provide a better, more polished product for our customers in the power and petrochemical industries. To provide “old school” service that was based upon a handshake, and where a service company does just that, provide service. Not only provide service, but provide only the best service, with spot-on pricing, punctuality, professionalism and utilizes a “service with a smile” approach. The company, much like myself has modest roots, remains humble in its demeanor and yet is very driven to succeed and be the very best at what we do.

Mona Thayer

Mona Thayer

Founder & CFO

Meet Mona Thayer. The other half of the President of PSI, Tom Thayer, Mona is our CFO and makes sure we all know where the money goes. Mona is also our party planner, designer, remodeling expert and fashion designer for any/all swag. On top of those things, she is also etiquette enforcer, and some would even say the voice behind the voice. She basically keeps everyone “on point” with our policies, protocols, expenditures and makes sure we are all trying to do our part in saving the earth by recycling. Mona is also the rock that tipped the decision scales in 2003 and pushed me to put our company on the map. Without her assurance then and continued drive now, PSI wouldn’t be the company it is today. You could say she puts the “power” in our Power Team.
