Executive Summary

Geraldine Tunnell has been Chief Marketing Officer of Dell Technologies since March 2024. She owns the company’s global marketing organization and all of its marketing work: brand, creative, online and media, demand intelligence, product and field marketing, and corporate communications. She joined Dell in 2005 after working as a management consultant at CapGemini Ernst & Young and at a Silicon Valley start-up in supply chain management, and before becoming CMO she led global field and partner marketing.

Professional Journey

Tunnell earned a bachelor’s degree in economics at the University of Virginia and an MBA at MIT Sloan. She worked as a management consultant at CapGemini Ernst & Young and at a Silicon Valley start-up focused on supply chain management.

She joined Dell in 2005 and held marketing roles across its businesses and product lines; Dell’s filings describe her as instrumental in transformation and customer-focused strategies. From 2018 to March 2024 she was senior vice president of global field and partner marketing, the marketing that supports Dell’s sales teams and channel partners.

In March 2024 she became chief marketing officer, directly responsible for the global marketing organization’s strategy and for brand, creative, online and media, demand intelligence, product and field marketing and corporate communications. Her Dell biography says she sees AI and generative AI as a rare shift in how marketing’s art and science combine to serve customers.

She is one of eight executive officers listed in Dell’s fiscal 2026 annual report, working alongside chief customer officer Bill Scannell and global sales president Pete Trizzino on the go-to-market side. Outside work, her biography says, she enjoys spending time outdoors.

Her remit spans every audience Dell sells to, which the company describes as ranging from global corporations and governments to small businesses and consumers. She sits on a leadership team in which every executive officer has spent at least two decades at Dell or EMC, according to the career histories in the 10-K; she joined Dell the same year as the company’s chief human resources officer, Jennifer Saavedra.
