Founded in Memphis, Tennessee on December 30, 1957 as the Fred P. Gattas Company,  we expanded into school supplies and equipment in March of 1994 with the acquisition of Al Graci Educational Service. Since that time, Knowledge Tree has expanded with additional retail outlets as well as the largest catalog operation dedicated to school equipment in the states of Tennessee, Mississippi, and Arkansas. We've proudly served the Mid-South as your best source for school supplies, curriculum supplements, furniture, office supplies, and toys for more than 25 years.
