Mueller Pye & Associates CPA has promoted three longtime employees to ownership positions as part of the firm’s long-term leadership succession plan.

Melissa Cain, Kelli Estrada and Brooke Hupp have become owners and directors of the firm, joining the leadership team as Mueller Pye & Associates continues a transition that began several years ago.

The promotions reflect the firm’s commitment to developing internal leadership while maintaining a client-focused approach that has defined the accounting practice for decades.

“Melissa, Kelli and Brooke have been with the firm for many years, and they have shown what it means to put clients first,” Managing Director Robyn Pye said. “Their tenure here speaks to their commitment, and their dedication has earned the trust and respect of both colleagues and clients. It is a privilege to welcome them into ownership and to know the firm’s future is in such capable hands.”

Cain, who joined the firm in November 2017, has nearly 20 years of experience in tax planning and leads the firm’s tax services division. A graduate of Texas A&M University, she specializes in business and individual income tax planning and works from the firm’s Katy, Texas, office.

Estrada has been with Mueller Pye & Associates since September 2016 and serves as director of advisory services. A certified public accountant with more than 10 years of experience, she focuses on business tax and advisory services, helping clients develop strategies to grow their businesses. She is based in the firm’s Loveland office.

Hupp, director of accounting services, was the firm’s first employee when she joined in November 2008. A QuickBooks ProAdvisor, she specializes in business accounting and helping clients better understand and use their financial information. She also works from the Loveland office.

Founder Paul Mueller said the firm also recognizes the support families have provided throughout the three directors’ careers.

“Behind every dedicated professional is a family that shares in the sacrifices and the successes,” Mueller said. “We are grateful to them as well.”

The CPA firm was established as Mueller & Associates in Loveland in 2008. It adopted the name Mueller Pye & Associates CPA LLC in 2017 when Robyn Pye joined the firm as a partner.

The ownership changes continue a succession plan that has been underway for several years. Teresa Mueller retired five years ago, and Paul Mueller transferred day-to-day leadership to Managing Director Robyn Pye on Jan. 1, 2026.

Paul Mueller said he will remain active with the firm through the end of 2027, focusing on strategic initiatives before transitioning to an “of counsel” role.

Mueller Pye & Associates operates offices in Loveland, Estes Park (by appointment), and Katy, Texas, with a staff of 13. The firm said the expanded ownership team positions it to continue serving clients while building on the firm’s longstanding reputation for accounting, tax and advisory services.
