    Bio
     
    “I inspire greatness for a better world by helping students explore the origins and meanings of American identity. One of the most challenging elements of changing the world is knowing where to begin. A deeper sense of national and personal identity can drive students toward a clearer vision of the change they want to achieve and can, as a result, help them to improve all of our lives.” 

    Fiona Halloran, Ph.D., teaches Upper School humanities courses, including American Studies, AP European History, AP U.S. History, and Food and Culture. She also helps to guide the Model United Nations program. Dr. Halloran earned a Ph.D. in American history from the University of California, Los Angeles, and holds a Bachelor of Arts in American history from American University in Washington, D.C. She is the author of Thomas Nast: The Father of Modern Political Cartoons. She has been supported in her research on American political cartooning and 19th-century history by grants from the National Endowment for the Humanities, the Huntington Library, the Gilder-Lehrman Institute, and the University of Oxford. 

    Before coming to LJCDS in 2019, Dr. Halloran taught for four years at Eastern Kentucky University and for nine years at Rowland Hall-St. Mark’s School in Salt Lake City, Utah. She is the parent of a member of the class of 2026 and is excited to see where an LJCDS education will lead him.

    “I feel strongly that through the journey of the college admission process, I am able to inspire greatness for a better world. As I tell every student who steps into my office, they are exactly where they need to be with regard to the steps that lead to college. Each student has their own educational path, and I am poised to help them get from wherever they might be when they first walk through the door to where they are headed for college.”

    Valencia Valentine Hamman joined the La Jolla Country Day School college counseling staff in 2007 after spending more than 20 years working in college admission. A native of Peoria, Ill., Ms. Valentine Hamman began her admission career at Beloit College in Wisconsin, where she worked for four years. Then she moved to San Diego, where she was a member of the admission staff at the University of San Diego for more than 12 years. Ms. Valentine Hamman also worked as a West Coast regional representative for Cornell University for four years, recruiting students from all over the West to attend Cornell. Admission work began for her as a way to give back to her alma mater, but it has become a lifelong passion.

    Ms. Valentine Hamman attended Beloit College, where she earned a Bachelor of Arts with a double major in French and psychology. She has lived in San Diego since 1991 with her husband, Peter, a facilities engineer for a start-up biotechnology company. They have two children: Jackson (LJCDS class of 2020), who attends Ohio Wesleyan University, and Isabella, a Cal Poly San Luis Obispo graduate. They all love being a part of the LJCDS family.

    “I inspire greatness for a better world by allowing my students a safe time and place to explore who they are and who they want to be as they try to discover how to get there. High school is a time for firsts and a unique time in our lives, where we really begin to delve into the world around us and the impact we can have. It gives me great joy to be on this journey with my students and to offer them a soft place to land through the process.”
     
    Mrs. Hirschy believes everyone needs a place where they can talk with someone who will truly listen and accept them as they are, and she works to provide a safe and warm environment in which this can occur.
     
    As the counselor to Upper School students, her role is to help all students in the areas of academic achievement and personal/social development to ensure today's students become the productive, well-adjusted adults of tomorrow.
     
    Mrs. Hirschy has been a counselor for more than a decade in New York, Colorado and California. Her passion is working with teenagers through the inevitable ups and downs of adolescence and ensuring that they always have a compassionate ear to which to turn when they need it.
     
    In her spare time, Mrs. Hirschy loves to spend time outdoors and exploring San Diego with her husband and two young daughters.
