Staff and Volunteers

Chastidy Ronan, Executive Director

In October of 2006, Chastidy and her husband found themselves facing an unexpected pregnancy. Having moved to San Francisco just a few weeks before, and between jobs, they needed some support. Alpha Pregnancy Center helped them through that difficult time. In January 2008, Chastidy began working as a counselor in our center, and in August of 2009, became the Executive Director. Having been in a situation similar to what many of our clients face, Chastidy delights in offering an understanding ear, most of the physical needs our clients have, and hope for a future to the woman and families that come to Alpha Pregnancy Center.

Ranelle Calub, Clinic Manager

Ranelle is a registered nurse with a compassionate heart that loves the Lord and loves His people.  She’s excited to launch our ultrasound program, knowing that it will be a game changer for the city of San Francisco.  

Faith Wirajsilp, Office Manager

Faith began volunteering at Alpha when she was in high school.  With her years of experience, she keeps the most important aspects of our vision central in all her work in our office.  Our clients say they feel an unexplainable peace when Faith speaks with them.


With out generous volunteers, Alpha Pregnancy Center could not operate. We always have room on our team for compassionate, loving people. Please contact our center if you are interested in being a part of the work we do.
