Of the services provided by Anthony’s, Jessie ensured that the company complies with the legal requirements under the Private Investigation & Security Agencies Act, 1973.

Manpower management is also Jessie’s forte and with her much appreciated effort, the security services of Anthony's had almost no turnover in manpower over the years.
