SDI Presence Welcomes Cloud Sales Veteran Don Clifton as National Account Manager

CHICAGO, February 1, 2023 – SDI Presence, LLC (SDI), the IT consultancy and managed services provider (MSP), announces the addition of Sacramento-based State, Local, and Education (SLED) expert and industry veteran Don Clifton to its accomplished sales team.

“Clifton joins us on the heels of a record-breaking sales year for SDI, and we’re optimistic that he’ll bring more success our way in 2023,” stated Chief Markets Officer Dawn Pfeiffer.

Clifton comes to SDI following more than seven years at multinational IT services and consulting company DXC Technologies, where he focused primarily on cloud solutions and digital transformation and served as point of contact for five western states as the firm’s Territory Director – SLED West. During his tenure at DXC, Clifton built strong, collaborative relationships with major tech partners, including Salesforce, Workday, AWS, ServiceNow, VMWare, IBM, Microsoft, and Google Cloud.

Before joining DXC in 2014, Clifton worked as a Sales Specialist for the former Global Technology Resources, Inc. (GTRI), which was subsequently rebranded Zivaro. In this capacity, he sold both data center and cloud solutions, including public, private, and managed hybrid cloud platforms to clients with more than 2,500 users.

Clifton has also worked for several other technology firms, including Dimension Data and Entisys Solutions, in the roles of Data Center Sales Specialist and SLED Data Center Consultant, respectively. He is a graduate of the University of California, Davis, and holds certifications in the Miller Heiman LAMP methodology and Solution Selling.

“I’m particularly passionate about solving customers’ biggest IT challenges and helping them transition securely to modernized infrastructure solutions,” said Clifton. “This is something SDI is well known for, so joining the team made perfect sense.”
