Culture & Team


At Thermo Systems, we have three simple goals:
Customer Success, Employee Success, and Financial Strength.




Thermo University


Thermo University is a unique, innovative training program to help ensure that our employees have the skills and knowledge necessary to perform their current work-related responsibilities and to provide a clear path forward for future growth and career development.

There are four main parts to the program: Control Systems Engineering, Safety, Business Development, and Management.

Safety is Our Priority


Thermo Systems has placed enormous emphasis on the safety of our employees and customers since our inception in 1998. Our entire team is OSHA10 certified and we require staff members who are management level and above to be OSHA30 certified. Our Director of Health & Safety along with our dedicated Safety Manager lead our safety team in conducting monthly toolbox talks and provide weekly safety tips to our entire team. Our ultimate goal is to provide our employees with as much safety knowledge as possible to ensure the highest level of safety on every job site.
