Donald C. Turnbow CPA PC

Firm Transition Announcement

Dear Valued Clients and Friends,

I am excited to inform you of an exciting development regarding the future of our firm.

After an exceptionally rewarding career, I am looking forward to retirement and spending more time with my family and friends. Having proudly served our clients for over 40 years, we have made the decision to transition the ownership of our firm.

As of November 1, 2025, Garza Cummings Blocher LLC (“GCB”) will be taking over client services for Donald C. Turnbow, CPA PC. GCB is a Dallas-based firm located next to Southern Methodist University and they have the same commitment to serving the local market as me and our team. This decision was made with great care and consideration. Our top priority has always been to provide you with the highest level of professional service. I am confident that this transition will provide our clients with a top-notch level of experience, focus, and overall satisfaction with GCB's tailored full-service offerings. As a result, we are confident you will continue to receive excellent service and support.

Here’s what you can expect during the transition:

We deeply appreciate the trust you have placed in us over the years. It has been a privilege to work with you, and we are excited for the future and ability to continue serving you.

Over the next coming weeks, we will be sending communications regarding the change in ownership and a celebration of my career. If you have any questions or would like to discuss this in more detail, please don’t hesitate to reach out to us at 214-553-1886.
