Experience success with CDP on your team.

Since its inception in 1981, CDP (Consultants in Data Processing) has been dedicated to the needs of Project-Centric organizations. CDP’s founding mission was to help companies assess, define and select application software and IT hardware. Realizing many of our clients were in need of a superior project management tool, CDP became one of the original founding Primavera partners. In 2008, CDP was recognized with the highest 3 year growth average internationally. Since the acquisition by Oracle in 2009, CDP continues to be a Premier Oracle | Primavera Partner in the US and Canada.

In addition to CDP’s partnership with Oracle | Primavera, we added partnerships with Dexter + Chaney’s Spectrum construction accounting software in 2009. CDP became Dexter Chaney’s largest independent Partner for software sales and service. In 2018, Viewpoint acquired Dexter Chaney and in 2019 Trimble acquired Viewpoint. CDP has adapted through all this change and remains the number one Partner for Trimble Viewpoint Spectrum software sales and service. This also provided CDP the opportunity to expand Viewpoint Services to Vista Job Cost and Team Project Management.

Although CDP has grown, our mission continues to be one of being able to provide our customers with superior skills, service, industry knowledge, and software tool selection.

CDP offers a full range of operations needs for our clients, including:

Originally founded in Charlotte, NC, CDP has expanded to include offices and training facilities in Maryland. CDP serves and supports clients across the United States. Our geographically dispersed staff allow us to minimize travel and provide a regional and local approach for most clients.

His consulting and training experience includes scheduling, project management, EVMS, job cost and estimating.
