Diane Cook, who is retiring as UM's vice president and treasurer after a 31-year career at the institution, says the people she encountered will be her most treasured memory of the University.
Clad in leather jacket and pants, the chinstrap to her motorcycle helmet securely fastened, Diane Cook looks quite like one of the “Ladies of Harley” as she rides on the back of her husband’s 1997 Heritage Springer. They rev up the bike every weekend, driving all around Miami on rides Cook describes as “pure fun.”
It’s a hobby many of Cook’s friends and coworkers never knew she had. To them, she is the University of Miami’s vice president and treasurer, a numbers guru who looks more accustomed to balancing the books than biking along a beltway.
But soon, Cook will have more time to devote to riding on a Harley, perhaps even learning how to drive it. After 31 years at UM—29 of them as treasurer—Cook is closing the books on a memorable career.
She leaves behind a university with an endowment 20 times larger than it was when she started, thanks in large part to her savvy investment skills and knack with numbers.
“When I started here, we had about $35 million in the endowment, and that grew to a peak of $700 million at one point,” Cook recalls.
To ramp up that figure, Cook and her team diversified the University’s portfolio, increasing the number of asset categories in areas ranging from stocks and bonds to real estate.

“Bringing our investment policies into the state-of-the-art with the risk tolerance level that the trustees wanted was important,” Cook says. “But it was gradual. We’re not risk-takers, but we definitely modernized the portfolio.”
UM President Donna E. Shalala lauded the vice president and treasurer at last year’s December commencement ceremony, crediting her “astute money management” knowhow for saving the University millions of dollars.
“Working with the University’s Board of Trustee’s Investments Committee, she has re-engineered the way endowment and pension funds are managed and developed new processes for manager selection for due diligence as well as for assets allocation,” Shalala said at the ceremony, where Cook received the UM President’s Medal.
Cook’s financial acumen was put to the test during the economic downturn, requiring her and UM’s treasury team to devise strategies to protect the institution’s assets. UM, she says, has weathered the storm “better than many, because we’re not that dependent on our endowment for day-to-day operating income. And that’s a good thing. Schools around the country that derive a lot of their budget support from their endowment have been really devastated.
“We also didn’t have as much commitment to some of the illiquid investment portfolios that some have, and that protected us from some of the weak performance that others got,” Cook continues.
She’s never been afraid of working with big numbers, even for someone who didn’t realize she had a gift with figures until she reached college. Cook graduated from high school thinking she would major in chemistry. After exploring various academic disciplines, she finally decided on finance, earning her degree in finance from Purdue University, where she worked for six years before coming to UM. She earned her M.B.A. from UM’s School of Business Administration.
Cook says her most treasured memories of the University won’t be of dollars and cents but of the people she encountered. “They’re absolutely wonderful,” Cook says. “From the faculty and staff to the trustees and students, everybody has such a wonderful view and outlook about what this University can do.”
She’ll also remember the Hurricane football team’s five national championship games, all of which she attended. She says she is proud of the University’s achievements, noting the exceptional faculty, the steady rise in the national rankings, and the increasing quality of students.
Cook’s last day at UM is Friday, March 26. She and her husband, a retiring airline pilot whom she met and fell in love with at Purdue, are moving to Tucson, Arizona, where she plans to do volunteer work with the Girl Scouts and, of course, enjoy Harley rides.
“The change of scene is going to be a delight in that 90 percent of all the vacations we’ve ever taken that are etched in our memories have been to the desert Southwest. So it’s going to be a treat to be able to walk out our door and be in that environment all the time.
“But Miami,” she says, “will always be home.”
