# Tutor Introductory Call with Brendan

> A relaxed 30-minute video call with Brendan Ellis, founder of Tooley House. We’ll talk about where things stand for your child, what you are hoping for, and whether Tooley Scholars (Business and Economics tutoring) or Tooley Futures (university and career guidance) would help. There is nothing to prepare and no obligation. Your child is welcome to join, but it is not necessary for this first conversation. Afterwards I’ll send a short note with what we discussed and a suggested next step.
