Paul and Robyn, partners in Mueller Pye & Associates Paul and Robyn“We have fun sharing our expertise with our clients, within the community and among ourselves so that together we achieve more than anyone thought possible.”

That’s our mission, and we take it seriously!  So much more than experienced accountants, we think of ourselves as gurus, heroes, and experts for our clients.  We believe in creating a positive impact, a ripple effect that benefits your business and family, and, subsequently, your community. We, also, give back to every community in which we have a presence, from participating in neighborhood events to sponsoring nonprofit organizations.

Our goal is to help you attain the success you desire - which means something different for everyone. It may mean building or selling a prosperous business, buying a bigger home or moving into a new office or warehouse, traveling, spending more time with grandkids, or leaving a legacy to your family, church, and community.

Our comprehensive approach works throughout different stages of your life - from buying a home, investing earnings, having a family, creating a nest egg, and retiring to pursue other interests -  to ensure you’re on track to get where you want to be.

Serving a broad range of business clients, from retail to corporate, we also specialize in working with nonprofit organizations, the oil and gas industry, and the craft beverage industry.

As your trusted advisor, we’ll provide the professional services, support, and advice you need to help you achieve your dreams.  


Mueller & Associates CPA was founded in Loveland, Colorado in 2008 by Paul and Teresa Mueller.  The Muellers purchased an existing accounting firm, and, in 8 years, quadrupled the size of that practice by devoting their tax and accounting expertise to business clients, their owners, and families.  The company now has offices in Loveland and Estes Park, Colorado, and in Katy, Texas.

In 2017, Robyn Pye joined the firm as a Partner and Director of of Tax Services, and the company changed its name to Mueller Pye & Associates CPA LLC.  Robyn and Paul had worked together in the past at the Mann Frankfort Stein & Lipp CPA firm in Houston for more than 10 years.  Robyn oversees the firm’s office in Katy, Texas, near Houston.
