Head of School
Nancy joined the Undercroft administrative staff in August, 2009. She first discovered Montessori education in 1986 when her son began attending a small Montessori school. Like many parents, she loved what she saw happening there and decided to pursue her Montessori training. She received her certification in San Diego and has taught children from early childhood through upper elementary. She served as a Montessori consultant for a public magnet program in North Carolina and, after receiving her state certification, served as principal of the same school. During that time, Nancy also earned her Master’s Degree in School Administration. A move to Illinois led to an administrative position overseeing the operations and educational programs of a network of retreat/conferences centers across the U.S.
Sydney joined the Undercroft Administrative Staff in June 2017. Sydney brings to Undercroft an extensive background that includes finance & accounting, human resources, education administration, and customer service. Her experience spans both for profit and non-profit sectors. She received her Bachelor’s Degree in Business Administration from Northeastern State University and also holds a Master’s in Business Administration. While Montessori was new to Sydney, she has found that it aligns with a lot of her personal beliefs and is enjoying being a part of the Undercroft Community.
Born and raised in the Tulsa area, Jamie received her Bachelor’s degree in Human Environmental Sciences from Oklahoma State University. Upon graduation, she lived and worked in Tulsa, Dallas, and the Boston metro areas for many years in the field of commercial Interior Design before returning home to Tulsa. Jamie joined Undercroft in 2016 as a parent when her daughter Ellen began the early childhood program, and in February of 2018 became our Administrative Assistant. Jamie serves as a primary contact person for parents, guides and children, and integrates school communication through weekly community emails and management of the Undercroft website and school database. She also coordinates admissions and enrollment for potential and enrolled families by coordinating tours and providing guidance through the enrollment process.
Brigid Vance joined Undercroft as the Development Director in 2018 after 11 years in nonprofit fundraising and communications. Her background is in all areas of funds development, including grants, special events, and capital campaigns. She received her Bachelor of Arts degree in American Studies and Italian from Scripps College. An Undercroft alum (1989-1997) and mom to a current lower elementary student (and future) early childhood student, Brigid is thrilled to bring her professional background to the school she loves so dearly.
Shannon joined the Undercroft administrative staff in January 2022 with a background in accounting, bookkeeping, and customer service and a passion for education. She received her Bachelor of Science degree in Organizational Leadership: Business Studies from Rogers State University in 2019 and is currently pursuing a second Bachelor’s degree in Accounting. An Oklahoma native, she called the Atlanta metro area home for over a decade before returning to Tulsa in 2018. Shannon was introduced to the Montessori method while expecting her first child and was thrilled to discover an educational approach that aligns with the values she seeks to encourage in her own home. She is delighted to be a part of the Undercroft community.
Phil joined the Undercroft administrative staff in November of 2018. He lived in Colorado most of his life and spent most of his career in Healthcare Facilities and Construction Management there. Having family in Oklahoma and coming to visit over the years, he decided to make the move to Oklahoma. Phil has been enjoying the open spaces and mild winters of green country. Although the Montessori philosophy is quite new to Phil, he is finding it enjoyable and interesting.
