Olasky & Sinsteden was formed in 2009 by Catherine Olasky and Maximilian Sinsteden, two American designers working in London.

Both came from the New York design world: Catherine spent five years working for Bunny Williams before moving to London to work for Sibyl Colefax & John Fowler, while Max began working for David Easton at age 15 before spending 3 years at Charlotte Moss.

The current partnership was born when the two re-connected in London where Max was completing an installation at the Victoria and Albert Museum. Since 2009, O & S has completed projects in Dublin, London, Guernsey, Nantucket, New York City, Houston, Austin, Connecticut and Boston.
