About QTC's History

About QTC Inc., a dream that started with doing any available work possible. Consulting, landscaping, construction and wireless communication.

This dream eventually evolved to where it is at today. A diverse general contractor, specializing in telecommunications along with commercial construction, electrical, and steel building services.

QTC originally started at Scott’s residence in Penryn, California. Our company began using a small shed as an office, and a tuff shed for tools. In addition, QTC’s very first vehicle was a 1990 Ford ¾ ton.

Scott, along with his kids (Candice, Jake, and Osh), officially started QTC in 2001. That is to say, family owned and operated ever since.

To sum it up, we are 200+ employees, that are all considered family.

The challenge of someone saying, “it cant be done” separates QTC from the rest. After all, QTC values its customers.

QTC operates primarily in California. Therefore, servicing nearly the entire state. While also carrying professional licenses in 7 western states.
