Jefunira Camp was founded in 1991
by Jeff and Ira

The story of Jefunira Camp starts in 1986 when I met my freshman roommate, Ira. It turned out to be a pretty good match and we became close friends. After graduation, we wanted to take a break before heading off to graduate school. Both of us loved working at summer camp so we decided that we would start our own. Our first summer we had eight campers. The next summer we grew to 15 campers and hired our first counselor. The rest is history.

Initially, camp had a different name.  But because Ira and I were such big parts of camp, everyone called it Jeff and Ira camp. With a bit of imagination, Jeff and Ira Camp became Jefunira Camp.  Around the time we changed the name to Jefunira Camp, we decided that running camp was something we wanted to do long-term. To ensure that we were following all of the best practices and procedures of an outstanding camp, we decided to seek accreditation from the American Camp Association (ACA). We have been accredited since 1994. Several years after we received our ACA Accreditation, we chose to become members of the Western Association of Independent Camp (WAIC). WAIC provides independent camp owners with a professional network and supports that helps all members ensure that every camper has the best possible camp experience.

After several years of running the camp together, Ira decided that he was ready to return to graduate school. He went on to get his PhD from Stanford University in Education.

Mary McClain

Camp Director

This summer will be Mary’s 20th year at Jefunira! After teaching for ten years in San Francisco, Mary is so so lucky because she now spends her summers AND the off season with Jefunira Camp! She is constantly working with Jeff to make Jefunira the best camp ever!

She also spends lots of time reading, playing, and laughing with her toddler son, Owen. When not chasing after Owen or playing at Jefunira Camp, Mary can be found running around on the soccer field, reading a good book, or rooting for the SF Giants!

Every activity at Jefunira is Mary’s favorite activity at camp but she thinks she is most looking forward to the peaceful calm during House of Cards and the hysterical laughter during Tip the Bucket.


We believe that kids thrive when they are outdoors, unplugged, safe, and having fun.
