About The Port

Occupational and Medical Clinic serving Brownsville, the Port of Brownsville, and the Rio Grande Valley since 1975.

The Port occupational and medical clinic facility in Brownsville

Our story

Since we first opened in 1975, Dr. Diaz and his staff have provided high-quality health services to families in Brownsville and the entire Rio Grande Valley.

As we grew, we expanded to the Port of Brownsville area. Today, board-certified physicians and physician assistants deliver occupational health, injury care, DOT and work-related drug screening, laboratory blood work, transportation and work physicals, x-rays, surgical procedures, and much more.

We are here to help workers stay on the job—with prompt, fast, high-quality medical treatment when it matters most.
