Leonardo Loo, Phoenix-office Managing Partner, Quarles & Brady 

meet Leonardo Loo

It is often said that one’s past does not determine one’s future. However, Leonardo Loo, who on October 1, 2018 was named the Phoenix-office managing partner of Quarles & Brady LLP, takes great pride in honoring his past as he helps shape Arizona’s future. 

“I was born in Venezuela, and my family roots are in China and Mexico,” says Loo, who is fluent in both Spanish and Chinese. “And my wife is African-American, giving our children a more diverse background than either of us.”

A member of the firm’s Business Law, Finance and International Services Law Practice Groups, Loo practices in the areas of mergers and acquisitions, commercial financing, international transactions, securities and general corporate law for clients in a wide variety of industries. Loo served as chair of the Phoenix Business Law Practice Group since 2014 before taking the reigns as Phoenix-office managing partner earlier this year. 

 “I was initially drawn to Quarles & Brady in 2011 by the firm’s team approach and its commitment to developing client relationships based on true collaboration. I am proud to be working with clients in the top of their industry like Arizona State University in its acquisition of the Thunderbird School of Global Management, as well as the work we’ve done for GlobalTranz Enterprises as part of its roll-up strategy, among many others.” 

Championing diversity and good works beyond the office, Loo currently serves on the board of directors for Chicanos Por La Causa, Inc., where he is the immediate past chairman. “CPLC has been a rewarding community organization to work with because its dedicated staff of over 900 directly impact more than 306,000 people annually throughout Arizona, Nevada and New Mexico.”

In addition to his leadership roles within Quarles & Brady and CPLC, Loo serves as general counsel for both the Arizona Hispanic Chamber of Commerce and the Black Chamber of Arizona. Arizona Governor Doug Ducey recently honored Loo with an official commendation for his service to the legal community and for his distinguished leadership. He has been named as one of the “Most Admired Leaders” by the Phoenix Business Journal, as well as among the top “Minority Leaders in Arizona” and “Arizona Business Leaders” by Az Business Magazine. Loo was also previously honored with a “40 under 40” award by the Phoenix Business Journal and is a graduate of Scottsdale Leadership Class XIX. Loo is also involved with the Arizona Asian American Bar Association, and in 2013 was honored by the Phoenix Chapter of the National Association of Asian American Professionals with its “Community Leader of the Year” award for his devotion to the community and outstanding service to the Valley. 

“As I settle into my first year as the Phoenix-office managing partner at Quarles & Brady, I see my efforts primarily focused in three key areas: First, our firm has enjoyed a rich history in the local legal and business community, and I am eager to continue to work with our clients to provide top-notch legal services and innovative solutions to meet their goals. Second, I want to deepen our commitment to our community through our various outreach, inclusion and volunteer programs, and pro bono work. Finally, I am looking forward to working with my colleagues to continue to cultivate and develop our internal talent while, at the same time, attracting skilled lateral attorneys as part of our growth plans in the Southwest. While competition in the legal services sector will continue to intensify, I am confident in our firm’s ability to operate well in that environment through our commitment to service excellence for our clients.”
