Bob Riddle, a 24-year veteran of Crossroads School for Arts & Sciences in Santa Monica who currently serves as assistant headmaster and dean of faculty, has been named the successor to current school headmaster Roger Weaver.

Riddle will assume the headmaster position at Crossroads in July next year, when Weaver plans to step down.

“The single greatest responsibility of the board of trustees is to select the most effective possible leadership for the institution,” said Peter Norton, chairman of the board. “Bob’s strengths as an educator and his vision for Crossroads School will allow us to build on the steady trajectory of ever increasing strength and effectiveness that was established by co-founder Paul Cummins and continued by his successor, Roger Weaver.”

Weaver added, “As an educational institution we know who we are and how and why we do the business of education as we do.

“Bob has had a long and distinguished career as an educator and leader at Crossroads. I am confident that he will preserve the clarity of Crossroads values, mission and identity and provide outstanding leadership in the future.”

Riddle said he is “deeply honored” to be named the third headmaster of Crossroads since the school was founded in 1971.

“Crossroads has such a rich history of progressive education as well as a strong sense of mission in its founding commitments, and I’m proud to be able to build on the legacy of co-founder Paul Cummins and current headmaster Roger Weaver to not only honor that history and protect those core values, but also move the school forward as we continue to provide a strong and well-balanced educational experience for our students.”

Riddle has served as assistant headmaster and dean of faculty at Crossroads School since 2003. He joined Crossroads in 1984 as a Middle School math and life skills teacher and became an Upper School math teacher in 1986.

Riddle was promoted to Upper School academic dean in 1988 and became Upper School assistant director and academic dean in 1995. In 1999, he was named Upper School director.

Prior to joining Crossroads, Riddle was a math teacher at Haverford Junior High School in Havertown, Pennsylvania from 1980 to 1981 and a math teacher at Bedford Junior High School in Westport, Connecticut, from 1981 to 1983. He earned a Bachelor of Arts in psychology and Bachelor of Science in secondary education (mathematics) from Pennsylvania State University in 1980.

In 1993 he was one of only 12 independent school educators nationwide to receive the Klingenstein Fellowship from Columbia University, Teachers College, where he received a Master of Arts in educational administration in 1994.

He is the co-founder of the Los Angeles chapter of the Gay, Lesbian and Straight Education Network.
