About Gateway Montessori School

Karen Grant and Dr. Michael C. Grant founded Gateway Montessori School in Longmont in 1982 to share classic Montessori education with local families. We are a nonprofit early childhood school on 9th Avenue serving toddlers from 14 months through kindergarten, governed by a board made up mostly of past parents and alumni.

Toddlers learn in our half-day Daffodil and full-day Daisy classrooms, which run year-round. Children 2.5 to 6 join mixed-age primary classrooms, where kindergartners in their third year lead the room, take on larger works and do more small-group unit study. Half-day preschool runs 8:30 a.m. to 1:00 p.m., half-day kindergarten 8:30 a.m. to 2:30 p.m., and full-day programs 7:30 a.m. to 5:30 p.m. Families pack a lunch and we provide healthy snacks.

We are licensed by the State of Colorado with a Level 3 Colorado Shines rating, validated by the Colorado Montessori Association, and members of the American Montessori Society and NAMTA. We accept Colorado Universal Preschool and CCAP funding and give a 10% discount for a second child. Our summer program runs ten weekly themed sessions from June to August, with park walks and water days on Fridays.
