Dennis Crandall

Principal Archbishop Hanna High School

A skilled, dedicated, inspirational, and caring educator, Dennis has served youngsters and young adults in education for over 39 years, and has led Hanna’s on-campus school, Archbishop Hanna High School, for the last nine years.

Dennis was instrumental in helping Archbishop Hanna High School earn one of the highest accreditation honors bestowed on a school. He also restructured the curriculum to serve a larger and more diverse population of students, added college preparatory and on-line accredited classes, and fostered greater day student opportunities for those youth who need specialized school assistance but don’t need Hanna’s residential treatment component.

Dennis also developed a number of new programs at Hanna including: Read to Succeed and Write-On programs (which focus on skill-building in reading and writing); organic gardens and orchard programs, which foster sustainability, water conservation, composting, and support our nutrition program; a viticulture program that features 150 cabernet vines and provides vocational training in the planting and maintenance of the vines, and harvesting of the grapes; and a wilderness and outdoor education program that features hiking, backpacking, rafting, spelunking, stewardship and volunteer spirit.

Prior to joining Hanna, Dennis worked at Cardinal Newman High School in Santa Rosa and served in a number of capacities including teacher, coach, development director, athletic director, assistant principal, and principal.

Dennis earned his B.S. in atmospheric science from U.C. Davis in 1972; a Life Secondary Credential in physics and math from Sacramento State University in 1974; and a M.A. in Educational Administration from St. Mary’s College in 1994.

Dennis is also a dedicated community member, devoting countless volunteer hours to community nonprofits including St. Joseph Catholic Church in Cotati and Cardinal Newman where he has served on their board of directors.
