Jarrow Montessori, a not-for-profit, private school and the oldest Montessori school in Colorado, was founded over forty years ago in 1964. The original founders, Christopher and Margot Brauchli, Florence Lennon, James and Prudence Scarritt, Andor Toth, Gary and Margaret Stahl and Hardy and James Frank wanted a quality Montessori experience for their children. Jarrow began as a pre school of twenty-one children operated out of the Sunday School wing of the First Christian Church in Boulder. The school burgeoned until in 1966, Jarrow moved to its present 3 acre site in North Boulder. Soon after that in 1969, Jarrow added kindergarten classes, expanded to 120 students and secured its founding Head of School, Janet Gollin, who led the school for twenty-five years with vision and enthusiasm. "I don't think it makes a lot of sense to educate children unless you involve yourself in the world they are going to grow up in."

By her tenth anniversary in 1974, Jarrow was expanding to include an elementary program which today continues up to the sixth grade. The school's enrollment now looks forward to over 190 students from ages 18 months through the 6th grade.

"When Keely and Pierce took their CSAP's for entry into middle school, they scored 12+ grade in math, English, and literature. Jarrow put them at a tremendous advantage compared to most of their classmates. This made the transition into a high school International Baccalaureate program effortles." —Deb Shafer, Neuro Kinesiologist
