Welcome to Saint Mark's Episcopal School in Upland, California. The efforts of many of our constituencies have made our website possible, and each link gives further insight into who we are and what we are about. We invite you to spend some time browsing our site. And, if you catch the spirit of Saint Mark's, then give our office a call at (909) 920-5565. Office hours are 8:00 a.m. to 4:00 p.m. Admission information packets are available and tours of the campus may be made by appointment. We value your interest and your questions and will give you the time you need to consider if Saint Mark's can play a role in the education of your child.
