About Us

Theseus comprises forensic psychiatrists and psychologists who lead the field of harassment, stalking and persistent complaint threat management.

Our team includes those responsible for the development of:

  • the Fixated Research Group,
  • the National Stalking Clinic, the UK's assessment and treatment center for individuals convicted of stalking behaviour, and
  • the Fixated Threat Assessment Centre [FTAC], the national threat assessment unit responsible for dealing with intrusive and threatening behaviour directed at members of the Royal Family, the Prime Minister and other senior politicians.

We complement this expertise with that of a small number of personnel from Royal and VIP security backgrounds. It is a unique, discrete and highly effective combination of skills. And one proven in the most sensitive settings.
