The NASA/Kelsey-Seybold Connection
Proudly Serving NASA since 1966
Kelsey-Seybold Clinic, Houston’s largest and most renowned private multi-specialty physician group, was founded by Dr. Mavis Kelsey in 1949. Dr. Kelsey began with one office in the Texas Medical Center and a vision of creating Houston’s premier medical practice.
This vision fueled the growth of an organization that today cares for more than 400,000 Houston-area residents and employs more than 360 highly qualified physicians and 2,150 employees.
With its unique network of 20 clinics, Kelsey-Seybold Clinic cares for local families as well as international patients who have made Kelsey-Seybold a family tradition. The National Aeronautics and Space Administration in 1966 selected Kelsey-Seybold Clinic to provide medical services to its astronauts and employees. This partnership continues today, with Kelsey-Seybold physicians onsite with astronauts at the White Sands Test Facility in New Mexico, Moscow and the Johnson Space Center right here in Houston.
