Tri-Tech, One Trusted Brand.

Owner, Larry Hoffman’s passion and respect for the industry dates back nearly four decades to his teens when he first put his eye to a theodolite.


He started Tri-Tech in 1994 with an ultimate vision to have a company that could provide a true turn-key service to accommodate a wide range of engineering, surveying and planning needs for residential and commercial clients.  Through numerous acquisitions, company growth and strategic business decisions he has accomplished this goal in partnership with his son, Lance Hoffman and has created the Tri-Tech Brand. Tri-Tech Surveying Co. & Tri-Tech Engineering work together as one team to provide services under one trusted name.
From its inception, the company has grown from a staff of about a dozen employees to approximately one hundred with offices in Houston and San Marcos.
