The Judge Celestino Guerrero Memorial Hospital began its journey in 2000 as a modest clinic named Klinika ni Dok, situated behind the Sta. Maria, Ilocos Sur town plaza. The clinic, initially staffed by just Dok Mila and Manang Luz, saw only a handful of patients each day. However, the clinic quickly gained popularity, with patients arriving in increasing numbers, often standing while they waited for their turn due to limited space. Over the years, the clinic expanded both in size and staff, leading to the establishment of the Judge Celestino Guerrero Memorial Hospital on April 27, 2009, a date chosen to honor the 88th birthday of Judge Celestino Guerrero. This expansion was a direct response to the growing demand for medical services from the community. In gratitude for the community's support, the hospital has committed to providing free medical services to underprivileged individuals annually. They conduct medical and minor surgical missions on the hospital's foundation day and on October 20th, in memory of Dok Mila's mother. Today, the hospital stands as a three-story building on Dakota St., Poblacion Sur, Sta. Maria, Ilocos Sur, with 21 staff members under the leadership of Dr. Mila Guerrero.
