U.S.-based payments solutions provider Ripple announced two key appointments on Monday, with former U.S. Treasurer Rosa “Rosie” Gumataotao Rios joining its board of directors and Kristina Campbell joining the firm as its new chief financial officer.

Ripple chief executive officer Brad Garlinghouse said on the company’s official website, “These two exceptional leaders join Ripple at a pivotal time for the company. Rosie’s experience in the public and private sectors provides an invaluable perspective to Ripple, especially during this time as the industry works to define crypto’s future. As well, adding Kristina’s extensive knowledge and success building teams and processes at rapidly accelerating businesses was a no-brainer. We are extremely fortunate to have them on the team as we continue our rapid international growth and to champion for regulatory clarity in the U.S.”

Rios was the 43rd Treasurer of the United States in the Obama administration. She received the Hamilton Award, the highest honor given by the U.S. Treasury Department for her contribution to the agency, including her initiative to place a portrait of a woman (American abolitionist Harriet Tubman) on U.S. currency.

“I’ve dedicated my career to financial inclusion and empowerment, which requires bringing new and innovative solutions to staid processes. Ripple is one of the best examples of how to use cryptocurrency in a substantive and legitimate role to facilitate payments globally,” Rios said upon joining the company. “Blockchain and crypto will underpin our future global financial systems. Cryptocurrency is the what. Ripple is the how.”

For her part, Campbell is expected to accelerate Ripple’s growth by driving its financial strategy and delivering value to shareholders at a time when opportunities are expanding across the globe.
