Morris Holmquest Tidwell

Welcome to Morris Holmquest Tidwell & Co.

We’re here to simplify taxes and financial decisions. Our goal is simple: to help you stay compliant, save time, and plan with confidence.

Morris Holmquest Tidwell & Co. was founded in 1986 by Jim Morris and Nan Holmquest after the CPA firm they worked for was acquired by a large national firm. They saw the need for a CPA practice focused on individuals and small businesses rather than large corporate conglomerates. In January 1986, they established Morris & Holmquest CPAs. In 1993, they were joined by Mary Alice Tidwell.

In 2024, after nearly four decades, Jim Morris (the last remaining partner) sold the firm to Derek Robinett, CPA, CFA®, PFS™, who now serves as managing partner.

He also holds credentials as a Chartered Financial Analyst® and Personal Financial Specialist™, allowing him to advise clients on estate, retirement, and broader financial planning needs.

Our values are simple: trust, clarity, and responsiveness in everything we do.
