Meet Weaver

A Special Welcome from our CEO

Why Weaver?

At our core, we’re a Texas-based, nationally-oriented accounting firm with comprehensive capabilities. That means we do the things you’d expect us to do: traditional assurance and tax services. However, our philosophy has always been about doing more than expected. That’s why Weaver also provides a wide array of advisory services including risk advisory, transaction advisory, IT advisory, energy compliance services, forensics and litigation, financial institutions consulting and public company services.

That’s what we do. But just as important is how we do it. Insight is at the heart of our approach. We start by making it our mission to understand our clients’ industries inside and out, with a special focus on oil and gas, financial services, manufacturing and government. It doesn’t end there; we get to know our clients’ business goals and challenges, what they want to achieve and what’s standing in the way.

International Reach

As a member of TIAG® (the International Accounting Group), Weaver can extend its reach through a worldwide alliance of more than 115 independent accounting firms in more than 70 countries.

TIAG members worldwide are committed to developing global working relationships with firms that have roots planted firmly in the local community, with branches that reach around the world. This global approach enables Weaver to provide excellent services to our clients both in the U.S. and abroad.
