Our History



The vision for the organization was conceived after many years of volunteer work in the field of education and years of involvement with educational strategic planning for new school construction and IT Master Planning. ConTech was created out of a vision to demonstrate the cost-savings and efficiency in up-front engineering of “intelligent” infrastructure design for security and technology in new construction.


From concept to implementation, our team of engineers and project managers are creative/critical thinkers with experience in education, government, business, law enforcement, and management information systems.  Unlike any other team of experts, this team has the ability to design and implement processes among multiple jurisdictions, departments, and agencies.
