Meet Our Administrative Team

John Triska
Principal, Mariposa @ Heather, Arundel, and Tierra Linda
  • I’ve been a teacher and principal for 35 years, working with TK-12th grades in far flung locations from Maryland to Humboldt County. For the last 10 years I’ve been here in San Carlos-- nine as Principal at Brittan Acres, and now at Mariposa.
  • When I’m not working with kids and families, I love spending time outdoors, especially on the water. If I was a bumper sticker kind of guy, mine would say, “I’d rather be fly fishing ANYWHERE.” My wife Christine and I also love spending time with our grandchildren, our grownup daughters, and our teenage niece and nephew.
Gina Tosetti
Secretary, Mariposa @ Tierra Linda
  • This is my second year at TL/Mariposa in the San Carlos School District. I started at TL assisting in their front office along side Cori Carpenter and I'm now the School Secretary for Mariposa Upper Elementary. Although I've only been working on a school campus for a short time, I've logged many hours volunteering in my children's classrooms and on the PTOs for their elementary and middle schools. I am currently on the Ingrid B. Lacy Middle School PTO board in Pacifica.
  • I love staying active with my husband and children. We enjoy camping, riding dirt bikes, hiking and the beach. I also spend many hours watching my boys play baseball!
  • I used to work for DreamWorks Animation and you can find my name in the credits of Shrek 2.
  • I also dislike greatly the feel of cardboard...silly but true!
