Ms. Bullock begins her 25th year in public education managing operations and facilities. Just prior to joining Urban Montessori Schools, she retired from OUSD as the Executive Assistant to the Office of General Counsel. She is very excited to return to the local public school sites to serve within a Montessori educational setting.


Buck is a third-generation art and technology geek who has been working in IT support for non-profits and artists for over ten years. He joined the Urban Montessori aftercare program in 2016 before moving into the office, and is proud to be a part of an amazing team! In his spare time, he keeps a garden, cats, and chickens, and collects music and art.
