Sierra Pett

Sierra joined Plancorp in 2022 as a Client Service Consultant. After graduating from the University of Tampa in 2018, she began her career with Enterprise Rent-A-Car and moved to Las Vegas, where she quickly advanced through the organization and became the youngest Branch Manager in the state of Nevada.

Born and raised in St. Louis, Sierra eventually felt the pull to return home. She moved back in March 2022 and joined the Plancorp team shortly after. In early 2023, she transitioned from Client Service Consultant into the newly created role of Onboarding Specialist, where she continued expanding her knowledge of the firm and the client experience.

At the beginning of 2026, Sierra continued her growth at Plancorp with a promotion to Client Service Team Lead. In this role, she serves as a key resource for the Client Service team, focusing on team development, training and onboarding, operational consistency, and day-to-day guidance. She is passionate about creating a supportive environment where team members can grow, collaborate, and provide an exceptional experience for Plancorp clients.

Outside of work, Sierra loves traveling the world, experiencing different cultures, and, most importantly, trying the local cuisine. When she’s home in St. Louis, you can find her visiting local wineries with friends, tackling 3,000-piece (or larger!) puzzles, and cheering on the St. Louis Cardinals, St. Louis Blues, and Kansas City Chiefs.
