Adam Caller’s firm, Tutors International, offers a personalised service to UHNWs around the world. They only offer long-term, full-time placements, and tutors are headhunted to meet clients’ needs. At a cost of around £100,000 to the client per year, Caller only recruits the very best; often ex-masters from public schools. Clients who own multiple homes or who want to travel are not tied to one location, but are able to build a long-term relationship with a tutor while retaining flexibility. ‘Kids today are expected to know a bit less about an awful lot more,’ says Caller. He believes that the academic rigorousness and emotional richness that comes from tutoring provides an effective antidote.
