Tiffany Condrill

Tiffany Condrill

Co-Founder

Tiffany Condrill met Jay while working as a substitute teacher in the Central Islip School District.  As a substitute teacher, Tiffany worked in many different classrooms, grade levels and saw many teaching styles, lesson plans and sometimes no lesson plans at all!  This experience helped produce the marriage, not only of Jay and Tiffany themselves, but also of their TeacherPlanBook.com idea.

Jay Condrill

Jay Condrill

Co-Founder and Chief Product Officer

TeacherPlanBook.com’s Jay Condrill is in his 17th year as a teacher at Central Islip High School in Central Islip, New York. Frustrated with taking so much time away from teaching and family to create – then annually recreate – a lesson planner, Jay developed the outline for an online lesson planner that would eliminate wasted time, improve lesson planning and integrate curriculum standards. This was the birth of TeacherPlanBook.com.
