About us
The company was conceptualized in the midst of a pandemic. It was founded by women with a vision to lift and empower individuals with similar values and entrepreneurial energy. Armed with unique skills and a burning desire to enhance the quality of life with pharmaceutical excellence, we set up Sierra Pharmaceutical Corporation.
​
Our company is named after the Sierra Madre mountain range in Luzon, Philippines.
