In April 1996, he was the first person ever hired to assist the Keeper of the Royal Philatelic Collection. Not a philatelist himself, he helped Keeper Charles Goodwyn and his adjoint Michael Sefi for simple tasks, such as keeping an eye on visitors consulting the collection and helping the Keeper throughout the Royal court and British government administrative lobbies.
But he was consulted on conservation problems too. He revealed himself as a philatelic exhibition organizer. In 2002, he travelled to the British Virgin Islands with the 1867 "Missing Virgin" error stamp of this British territory. The same year, he created for Elizabeth II's Golden Jubilee an exhibition which travelled in the United Kingdom.
In January 2003, when Sefi became Keeper of the Royal Collection, Surésh Dhargalkar was promoted to adjoint of the Keeper.
