CoreSite Realty Corporation has enjoyed an incredible rise to national prominence since its conception in 2001 . A carrier-neutral data center provider , it operates 19 such centers in eight metropolitan areas across the US , creating a service for over 1000 customers of every size and value . Jay DiMaggio is the Director of Real Estate and Construction at CoreSite , and became involved in the industry because , after training to become an architect , he quickly discovered that – in his own words – he wasn ’ t cut out for it . “ I realized I was a very bad architect ,” DiMaggio wryly says . “ But I love architecture , and this way , I get to work with really great architects and engineers . I was with the Walt Disney Company for 12 years and wanted a change , then became involved with Carlyle Realty Group West who , in 2009 , changed the company ’ s name to CoreSite . In 2003 we were all of a sudden building data centers ! The rest is history and a great history it has been . I ’ ve been with CoreSite for 15 years , almost from its beginning , but I never had a long-term vision . Carlyle Realty Group West was not really a data center developer or operator back then , but very quickly morphed into a very profitable investment . Today I am still amazed as to how the company began but as I look back the recipe is pretty simple . Take a lot of smart , hardworking and creative people , who care , and success is imminent .
