Principal's Message

Dear Family and Friends of San Gabriel Mission High School (SGMHS),

Thank you for your interest in SGMHS—the only parish high school in the San Gabriel Valley which happens to be on the historic grounds of the 4th California Mission - Mission San Gabriel!  We are delighted that you are considering us and welcome the possibility of working with you to educate your daughter.


Over 75 years ago, SGMHS Claretian Parish Priests, the Dominican Sisters, and parishioners devoted themselves to a labor of love that continues to this day. I can only imagine how much faith, hope, and love our founding parishioners, sisters, and priests must have felt when they committed themselves to starting a co-institutional high school that would serve their young men and women and those of surrounding parishes. Everyone at SGMHS shares their commitment and their love and since 1971 it has been devoted to the education of young women in a single-sex environment. I am confident that our founders—and all those who have gone before us—would be pleased to discover that their faith, hope and hard work have paid off.


For nearly thirty of SGMHS's 75 years, I have been blessed to be a member of this community as student, teacher, and administrator. In my time here, I have participated in the work of the school in many different capacities, but feel especially honored to serve as principal of my Alma Mater Mission High.  Today, Mission empowers young women to be Christian Leaders for the world while making them college confident and personally grounded in the love of God, self, and others.


I invite you to learn more about us. Our website will give you a good idea of the opportunities we offer, but nothing compares to coming to experience it yourself. Please come and see what Mission High would be like for you. Join us for mass, take a tour of our campus, talk to our teachers, administrators, and staff, or ask one of our students or parents about their experience here. We’re sure that once you get to know the Mission family, you’ll want to be a part of it!


God Bless you and your Family,

Ms. Raquel Cagigas, M.A., M.A., ‘96
