Texas Clinic was founded out of necessity and compassion in the fall of 1984. When a government-funded opioid treatment program in Houston Heights abruptly lost its funding, psychiatrist Manazir Shamsi, MD — an experienced physician in addiction medicine — stepped in to ensure patients would not be left without care. By December 1984, he had filed the necessary applications and launched the first Texas Clinic location on Westview Drive in the Spring Branch area.

The response was immediate and overwhelming. Texas Clinic Westview quickly reached capacity, underscoring the urgent need for high-quality substance use treatment in Houston. Just 10 months later, in October 1985, Dr. Shamsi expanded operations and opened Texas Clinic Fulton, initially occupying part of a building that also housed the headquarters of Clayton Supermarket. As demand continued to grow, the clinic eventually expanded into the entire space.

In February of 2000, Dr. Shamsi’s youngest son, Farhan, became the Program Sponsor of Texas Clinic Westview, continuing the family’s commitment to compassionate care. In December 2024, 40 years after opening its doors, Texas Clinic Westview also moved into a new modern facility near Westview and Campbell—designed to provide a warm, welcoming environment for recovery and healing.
Today, Texas Clinic is proud to have served thousands of clients throughout the Greater Houston area.
