With just four months before Colorado seats a new state treasurer, Ryan Parsell, the office’s second-in-command, is returning to El Paso County.

The office announced Friday that Sandy Tan will become the deputy state treasurer, presumably until Walker Stapleton leaves office in January.

Stapleton, the treasurer since 2011, is the Republican nominee for governor.

Parsall became Stapleton’s deputy last year after serving as deputy chief clerk and recorder in El Paso County. He will be county government’s chief public information officer.

Parsall replaced Jon Forbes, who quit after cursing, including the f bomb, at the board members for the Public Employees Retirement Association (PERA) a month earlier. Forbes had held the job since 2015, when he succeeded Brett Johnson, Stapleton’s original deputy treasurer.

“It has been an honor and a pleasure to serve as deputy treasurer,” Parsell said in a statement Friday. “Walker has been a real mentor to me during my time here, and I have learned so much from working along side him as he pushed for meaningful (pension) reform, brought more transparency to state government and found creative ways to inject more capital into our public schools.”

Tan’s promotion takes effect Oct. 1.

“Ryan’s managerial and leadership skills were invaluable to this office over the last 18 months, and while we are sad to see him go, we wish him nothing but the best in his future endeavors,” Stapleton said in a statement. “At the same time, I am excited to elevate Sandy to this new role. She has been working with the treasury for over a decade and has experience in all areas overseen by the department.”

Tan has been the office’s acting unclaimed property director, operations director and cash manager. Before going to work for the state, she was the assistant treasurer, reconciliation and banking relationships manager at Janus Capital Group.
