My name is Sarah Barry and I am very excited to join the staff here at John Jay High School.  I am a Special Educator who will be teaching Resource Room and co-teaching Biology.  I have been in education for many years- most of those years with the New York City Department of Education.  I also spent some time teaching in Brisbane, Australia.  I received my undergraduate degree from Hobart and William Smith Colleges and my Master's degree from CUNY Hunter College.  When I am not teaching, I am chasing after my two young sons and pursuing a PhD at Fordham University.

Rebecca Davidson, school counselor

 Rebecca Davidson 

Hi everyone! My name is Rebecca Davidson, and I am a school counselor at John Jay High School. I am so excited to join such a collaborative, supportive, kind, and caring community of educators, students, and families, and I couldn’t be happier to have landed in the Katonah-Lewisboro School District! I am coming to JJHS after 5 years in the NYC Department of Education, working as the Counseling Department Chair at The Brooklyn Latin School, a specialized public high school in Brooklyn. Previously, I received my master’s degree in counseling at Hunter College, and my undergraduate degree at The University of Delaware. I am originally from the Boston area, and I recently moved from Manhattan to Connecticut with my husband and 15 month old daughter! From being in the district for only a few short weeks, I can already feel the warmth of the community and I’m thrilled to be a part of it! Please feel free to stop by my office at any time to say hello!

Julia Fitzgerald, school nurse


My name is Julia Fitzgerald, I am the new full-time registered nurse for John Jay High School. I grew up in Mahopac, NY and studied at Pace University where I obtained my Bachelor of Science in Nursing. Throughout my college career, I learned hands-on care in many different hospitals and medical facilities throughout Westchester and NYC. After completing my degree, I went on to take the New York State boards to become a registered nurse. I began my nursing career as a medical surgical nurse at White Plains Hospital working with a variety of patients of all ages. Throughout the pandemic, I gained valuable knowledge from my experience in the field by treating those with Covid-19. During these difficult times I learned the importance of adaptability, teamwork and empathy. In addition to working in a hospital environment, I also have experience working per-diem for Affiliated Physicians where I performed screening for Covid-19 signs and symptoms, as well as Covid-19 testing. My love for health care and being part of a tight-knit community is a big part of my life. In my leisure I enjoy outdoor activities, baking, arts & science, and staying active. I am excited to be joining the Katonah-Lewisboro School District where I hope to make a positive impact on the school district as a whole.

Jared Henderson, Band

 Jared Henderson 

Greetings! My name is Jared Henderson. I am absolutely thrilled to be a part of the Katonah-Lewisboro school district and community! I will be teaching Band, Music History & Theory, Jazz Band and Pep Band this year. My primary instruments are Bass and Tuba. I grew up in a small town in Oregon, and greatly benefitted from being raised in a tight knit community - which is one of the reasons I’m very excited to be teaching at JJHS. I went to Berklee College of Music in Boston for my Bachelor’s and Master’s in Music Performance. I later attended CUNY Brooklyn College for my graduate certificate in Music Education. I lived in NYC for several years where I was very active as a professional bassist and have been fortunate to perform around the world. Prior to working at John Jay, I taught middle school band in Malden Public Schools (Boston, MA) and in the East Ramapo Central School District (Rockland County). Aside from music, I enjoy spending time with my family, gardening, hiking and running.
