Our History

Dr. Martha Manquero-Butler’s story begins with an innate desire to help people. She always wanted to treat the sick. Dr. Manquero-Butler has treated patients for more than 20 years. Dr. Manquero-Butler realized there was a lack of care for homebound patients, which led her to fill this void. Dr. Manquero-Butler has focused on house calls, providing compassionate care during these visits.


New Light Primary Care has now migrated to in-office services. Our facility, located on the east side of town, is now open! As we continue to serve the El Paso community with trusted care, our new location offers additional services such as X-rays, blood tests, and much more.
