Danielle Buckman was selected as the new principal of Windsor High School (WHS) for the 2023-24 school year. This school year marks Danielle’s 14th year in the District, having taught for six of those years as a math teacher at Windsor High School. She served as the District’s Math Teacher on Special Assignment for two years, helping staff members implement new math standards and assisting students. Before becoming WHS’s Principal, she served as Assistant Principal at WHS for the 2022-2023 school year. She holds a bachelor’s degree in psychology with a minor in math, and she holds a single subject credential in math. She also has a master’s degree in education with an emphasis on Teaching and Learning and Instructional Leadership and Amins
Danielle is passionate about education and looks forward to continuing to make WHS the best possible experience for all students, parents and community. Her goal is that every student feels seen, valued and knows they can be successful at Windsor High School. Students are welcomed and encouraged to stop by her office and say hi.
Danielle is a Windsor resident and Mom to daughter, Wyla. “My daughter Wyla is my world. I strive to be a positive role model for her and want her to always be proud of her mommy.”
“Danielle is a great example of why Windsor likes to take a “grow-your-own” mentality when it comes to our administrators,” said Director of HR Pete Sullivan. “She has grown professionally as a part of our District and evolved into the top position. In return we get a dedicated, experienced staff member who knows our District from bottom to top.”
The Windsor Unified School District (WUSD) is pleased to announce that Stephen Summers will be the new assistant principal for Windsor High School (WHS).
Summers comes to WUSD from up north, serving in both Willits and Ukiah. This is his 13th year in Education —he taught for his first four years in Willits Unified where he was the Middle School Athletic Director for all four years while teaching Community Day School, Middle School Math, and High School Math. He was also the Head Coach for the Baseball program (1 year JV, 3 years Varsity), Head Coach of 6/7th Grade and 8th Grade Girls Basketball (4 years), and a High School Football Coach (Offensive line, 1 year). He has been at Ukiah High School, for the last 9 years where he has taught Math, and most recently been the Athletic Director (last 4 years). He was also the Head Varsity Baseball Coach for 6 years (2015-2020) and the Assistant for the Varsity Girls Basketball program for 2 years.
Before starting his career in Education he attended Missouri Valley College where he played Baseball and graduated with his B.S. in Middle School Education with a concentration in Mathematics.
“Stephen ticks all the boxes for what we were looking for in this role,” said WUSD’s HR Director Pete Sullivan. “His extensive background in athletics and at the secondary level makes him an ideal fit for WHS.”
“I am honored by the opportunity to work for Windsor Unified and serve under Superintendent Decker and Principal [Buckman],” Summers said. “Their passion and commitment to excellence is contagious. From the energy on campus to all of the different pathways available to the students, Windsor High just felt right.”
Summers won’t be coming to Windsor alone, he’ll be bringing his family, and Windsor’s family-friendly reputation was a big draw. “My wife Katie and I are excited to move to such a family-oriented community like Windsor. Raising our two sons, Hudson and Calvin, in Windsor was one of the driving forces for our move.”

“We feel very fortunate to have someone with Sean’s experience and passion joining our WUSD community,” said Superintendent Jeremy Decker. “‘We know Windsor High School will only benefit from his presence and support.”
Kerr is eager to be a part of his new community here in Windsor. “I love working with high schoolers and enjoy guiding and advising students as they look to further their education and their lives,” he said. “I was interested in Windsor because of the community. I very much look forward to finding my new home at Windsor High School.”
“Sean brings a wealth of experience, and a strong ability to connect with kids and meet them where they are,” said Director of Human Resources Pete Sullivan. “His genuine enthusiasm for the role and his love for the work shines through.”
When asked what he hopes to bring to his new role in Windsor, Kerr responded, “Enthusiasm, positivity, consistency and kindness. My goal is to bring spirit and curiosity to life and hopefully add some fun and positive energy to an already thriving program.”
Kerr looks forward to sharing his new community with his “two wonderful and talented kids. A current senior, and freshman in high school.”
Kerr will move officially into his role on July 1. Windsor Unified School District is excited to welcome Kerr to Windsor High School and invites everyone to join in giving him a warm welcome.
Chris Catelli holds a Bachelor of Arts in Social Science Teacher Education from San Diego State University.
He began his teaching career at Windsor High School in 2015 and taught full-time through 2023. He’s also worked as a coach for Cardinal Newman High School (in Santa Rosa) for over a decade. After working for the Sonoma County Office of Education for 6 years, he’s happy to return to WHS as our new Assistant Principal.
As an educator, coach, and pathfinder, Chris wants individuals to take on challenges that push them to think critically about their lives and the world around them. “I firmly believe in the idea that constantly learning is the key to establishing a fulfilling life,” he said. It is his aspiration to work with others to explore passions and embrace the idea of making mistakes we can learn from in order to achieve creative solutions that shape how we live our lives.
