Kelsey-Seybold Clinic Pasadena

As famous for the NASA luminaries they treated as they were for practicing preventive medicine, Kelsey-Seybold Clinic had its beginning sixty years ago when Doctors Mavis P. Kelsey, William D. Seybold and William V. Leary decided to leave the Mayo Clinic and build their own group practice. A 5th-generation Texan, Dr. Kelsey arrived 1st, opening an office near the fledgling Texas Medical Center. On January 15, 1949, he saw his 1st patient, and on March 15, he moved into the Hermann Professional Building.
