Mark D’Amato and Guy Conversano founded DCI in 1988, beginning the adventure out of one of their basements. From the start, they were committed to creating the kind of environment that would enable employees to thrive and make clients want to come back. That same tradition of commitment to our clients and employees alike continues to fuel the leadership of today.
DCI has long been on the leading edge when it comes to industry technology, but for us, technology is more than just new gadgets: it’s combining the promise of these new tools with our history of innovative ideas to save our clients money.
DCI is based in Seattle, with offices in Spokane, Portland, San Diego, Austin, Irvine, San Francisco, and Anchorage. We are licensed in all 50 states and most Canadian provinces.
