A legacy that lasts
At Prothro, Wilhelmi & Company, our work is grounded in something deeper than just numbers. What began as a solo venture by Thomas G. Prothro in 1992 has grown into a trusted, multi-partner firm serving individuals and businesses across Tyler and East Texas with clarity, care, and principled guidance.
As our mission statement says:
“We believe that by possessing ethical and eternal values, an individual or business has infinite potential to succeed.”
A foundation of
faithfulness
Though our team and services have expanded, our foundation remains unchanged: personalized service, long-term relationships, and a commitment to our values.
