Julia is a Londoner by birth and has lived in the UK capital all her adult life. After a career as a book editor with leading art publishers she qualified as one of London's respected Blue Badge Tourist Guides. Her familiarity with the city means she not only knows the major sights but also its more hidden corners.

As an alumna of Smith College, Massachusetts, Julia has a particular interest in American connections in London. World War II has long fascinated her and she likes to take visitors to the Churchill War Rooms and other places connected with wartime London.
