About Trinity Source Group, Inc.

“I wanted to follow up with you in writing to let you know that the passive, sub-slab venting system you designed for our old industrial building in East Palo Alto worked perfectly. The trace amounts of solvent are gone.

Your innovative and affordable design enabled us to lease that space to a new, clean medical use, rather than another dirty, automotive or manufacturing use. This, in turn, has created a far more valuable real estate asset for our partners.” – Real Estate Client
