Columbia Greenhouse’s greatest strength is our vibrant, talented and dedicated faculty. Our faculty work tirelessly to build trusting connections with our students because we know that young children learn best when they feel securely wrapped inside a warm and loving relationship. Supporting each individual child as they explore, learn and make sense of their world is a primary goal of Greenhouse’s faculty.

As a community of learners, we are firmly committed to professional development. In addition to attending local, national or international workshops and conferences, we meet regularly as a whole staff to share and build onto our own intellectual pursuits. We ask questions, discuss ideas, and review current research; always in pursuit of honing our thinking, skills and knowledge of early childhood education.
