Craig is originally from Southern California and came to the Cate community after teaching science at Loyola High School of LA and LMU.

Craig is passionate about many things that Cate embodies, such as being part of a vibrant learning community, enjoying the beach and the mountains, and being amazed by the natural world. Craig wants to share this inspiration with his students, regardless of whether they plan to pursue science in college because he believes that people are inherently curious and capable of appreciating, learning, and doing science.

Craig lives on the Mesa with his wife, Christine, who teaches K-5 science at Crane Country Day School. They have two sons – Willem, ’22, who attends the Tepper School of Business and plays football for Carnegie Mellon University, and Henry, ’25, who enjoys surfing, math, science, volleyball, and football at Cate.

Despite previously living on the East Coast her entire life, Beth Caylor has always suspected herself to be a native Californian. She joined Cate after five years at The Lawrenceville School, where she was a Science Master and Assistant House Master.

Throughout her career, Beth has been drawn to opportunities to share her passion for environmental and biological sciences through teaching. She has been fortunate to lead field programs to The Island School in the Bahamas, develop and implement a program in Hawaiian Oceanography for Johns Hopkins Center for Talented Youth, and teach Caribbean Oceanography aboard SSV Ocean Star in the Sea-mester Global Program. Beth has M.S. degrees in science education and curriculum studies from Indiana University as well as in marine science from the College of William and Mary. As an undergraduate at the University of Virginia, she participated in the Semester at Sea program and dual-majored in biology and studio art.

Paul has spent most of his life on the Mesa. He first came to Cate in 1968, when he was six years old, his father having accepted a position to teach in the English Department. After graduating from Cate in 1979, Paul studied biology at Middlebury College, returning to Cate in the mid-1980s to begin a teaching career that is now in its thirtieth year. Paul has taught biology, chemistry, genetics, anatomy and physiology, and an interdisciplinary course he developed (“The American Wilderness”) to integrate environmental science and the writings of the nation’s foremost naturalists. In addition, Paul has served as Associate Director of Admission and Dean of Students, and he has served as dormitory supervisor since he arrived. In his over 15 years as the boys varsity lacrosse coach, his teams have won 15 league championships, capturing the state title in 1994.

In addition to his general love of outdoor sports such as rock-climbing, backpacking, fly-fishing, surfing, and mountain biking, Paul is certified as an ACA whitewater kayak instructor and as a wilderness first responder. He has kayaked extensively in North, Central, and South America, and in 1987 he introduced the sport to Cate, where it has been an integral component of the Outdoor Program ever since.
