The History of Castro & Co.

We Are Committed to Providing Pro Bono Work

Castro & Co. is currently in the process of establishing the first low-income taxpayer clinic in Dallas, Texas. As the only major metropolis in the United States without a low-income taxpayer clinic, the low-income families of the Dallas-Fort Worth Metroplex will substantially benefit from this clinic that will offer free, high-quality tax services to families that have certified their low-income status.

We are also devoted to serving the surrounding low-income communities. All international tax attorneys and professionals at our firm are required, as a condition of employment, to devote a respectable number of hours each year to pro bono activities, including the soon-to-be-established tax clinic.
