Catherine Nyongesa

In 2010, Nyongesa and her husband, a practicing pharmacist in the Houston-area, Texas, United States, started Texas Cancer Centre Nairobi. Initially the Centre only offered chemotherapy treatment as an outpatient service. Later, the couple borrowed KSh100 million (approx. US$1 million), to built an inpatient facility at a second location in Nairobi. With assistance from the University of Texas MD Anderson Cancer Center, the Nairobi center acquired and installed a radiotherapy machine, set up a diagnostic laboratory and acquired x-ray machines and ultrasound equipment. As of March 2015, the Centre had over 70 full-time staff, handling over 150 outpatients daily, and offered accommodation at a reasonable fee to out-of-town outpatients. As of July 2017, the Texas Cancer Centre has expanded to a total of four locations in Nairobi and Eldoret.
