Jonathan Frecceri
Head of School
Jonathan joined Lydian Academy as the Principal in 2017, where he integrated his experience as a PPS credentialed school counselor, special educational consultant, and licensed Marriage and Family Therapist (LMFT) in optimizing educational and wellness programming for unique student learners. His background prior to Lydian consisted of working with neurodiverse students with IEP's and twice-exceptional learning profiles who required a combination of mental health and academic supports to access their learning, and this experience proved incredibly useful when it came to listening to each Lydian student's specific needs and learning objectives, and creating personalized education programs to support those endeavors.
Following the Lydian Founder’s retirement, Jonathan stepped into the Executive Director role for the organization, and helped to staff/recruit Leadership team members for the opening of a 2nd campus location in Burlingame, CA in 2021. As the current Head of School, Jonathan oversees all aspects of admissions and outreach, academic advising, post-secondary / transition planning, and mental health consultation for both the Palo Alto and Burlingame campus locations.
Prior to Lydian, Jonathan was an Adjunct Faculty member in the graduate school of education at the University of San Francisco, the Mental Health and Wellness Coordinator at Palo Alto High School, and a psychotherapist in private practice. Jonathan helped develop the K-12 Toolkit for Mental Health and Suicide Prevention, which was released and distributed to school superintendents in California in May 2017 in support of AB2246. Since 2010, he has worked at the intersection of mental health and education, including consulting work with the HEARD alliance, Stanford University, Project Safety Net, and the American Foundation for Suicide Prevention (AFSP).
Some of Jonathan’s greatest accomplishments include spearheading a comprehensive Wellness Initiative that included the opening of Palo Alto High School’s first teen Wellness Center, and speaking engagements with PAUSD’s Wellness and Support Services leadership team at two national conferences.
Jonathan graduated Summa Cum Laude from the University of Notre Dame with a B.A. in Psychology and English, and holds a Master’s Degree in Counseling Psychology from the University of San Francisco. He is a proud father of 5 children and two furry felines, a Harry Potter and Game of Thrones fanatic, and loves spending his free time in movie theatres and outdoors in Sonoma / Monterey counties.
