Career

Adda Quinn built a distinguished career in environmental research and project management after her divorce from Larry Ellison in 1974.

She joined the Electric Power Research Institute (EPRI) in Palo Alto, serving as a Business Manager in the Environmental Division.

In this role, she managed large research budgets and directed projects focused on global climate, ecology, land and water quality, and risk assessment.

Her work required close engagement with scientific publications and positioned her as a key contributor to advancing discussions on environmental and climate issues.

After a decade as Business Manager, Quinn transitioned into a specialized role as Project Manager within EPRI’s Land and Water Quality Program.

This position expanded her responsibilities to supervising critical research on complex environmental issues, including contaminated sites, treated wood poles, and PCBs.

Her career at EPRI spanned many years and reflected her ability to balance demanding professional work with a vibrant personal life, where she pursued activities such as snow skiing, sailing, and backpacking.

Through this period, Quinn demonstrated her ability to combine scientific focus with leadership in addressing pressing environmental challenges.

Beyond her career at EPRI, Quinn’s life continued to reflect both professional dedication and personal passion.

She later married George Sublett, with whom she shared interests in horse riding and traveling extensively.

While her first marriage to Ellison connected her to the early years of Oracle’s history, her own legacy stands firmly on her accomplishments in environmental project management and research.

She further enriched her later years through volunteer work and hobbies such as cooking and gardening, leaving behind a record of meaningful professional achievement and personal fulfillment.
