At CTI, we believe that every member of our team is critical to our success from our engineers to our sales team to the folks on our factory floor and in our custodial and shipping departments.  Many of our employees have been with us for more than 25 years – a testament to our core values that form the basis for maintaining a culture in which we treat each other – and our customers, distributors, partners and vendors – with respect and the way we would like to be treated. 

CTI is not just a manufacturing company.  Starting with the CEO, it is also a company of engineers.   But unlike some engineering-driven companies, our focus is less on the latest “bleeding edge” technology and more on meeting the needs of our customers.  And rather than tell our customers what we think they need, we have an unwavering commitment to listen to our customers and to meet their needs with practical, simple, easy-to-use products and applications.

Vice President of Software Development
