An Overarching Philosophy of Honor & Respect

Guiding everything we do at Cornerstone is recognizing the dignity of each and every individual that will ever be affected by the projects on which we work – our employees, our clients, and the people who use the buildings we commission. Dignity garners a need for honor and respect, which are at the heart of Cornerstone’s values. Those values are felt and lived in everything our team does.

And speaking of values, we’ve taken the time to define the tenets that matter most to our company and guide how we work. If our core values resonate with you, we hope you’ll reach out for one of our open positions or share your resume with us to see if there’s a potential fit.

Core Values

Passion for Performance

Cornerstone was born from a desire to do things better: commission and deliver buildings more expertly and efficiently, and ultimately improve the commissioning industry as a whole.


At Cornerstone, we are trusted client and owner advocates, so integrity is at work in everything we say and do – especially when it comes to making sure owners get what they paid for.

Culture of Health

Cornerstone believes that the health, safety and well-being of all aspects of our work matter. We promote a global view of the health of the environment by considering how our services can positively impact the present and future.


At Cornerstone, we’re a committed team of problem solvers working together toward common goals. We engage with our coworkers to strengthen our culture and move the firm forward, and integrate with Client Project Teams to help deliver the very best buildings possible.

Continuity of Communication

Everyone at Cornerstone believes that pro-active, open and honest communication, both internally and with clients, is a key component of success.

Hands On

Our biggest differentiator is that our commissioning process is hands-on. We pride ourselves on solving problems, not just spotting them. Not a lot of other commissioning firms can say that.

If these values resonate with you, let’s start a conversation. You may be the next perfect addition to our team.

Cornerstone is located in New England (including greater Boston/Cambridge metro), the Mid-Atlantic (DC/MD/VA and down to Florida), the Midwest and West Coast.
