Castalia

Castalia was founded in 1980 by Roland Leroy, and built around innovative thinking on the organisation of public services. Castalia pioneered public private partnerships in infrastructure around the world. The firm drew on French models such as lease and concession contracts, and adapted them to work in diverse circumstances in Europe, Asia, Africa, Latin America, and the Caribbean.

Since 1980, the company has grown in staff numbers, international coverage, and areas of work. Led by Chief Executive, David Ehrhardt, and Executive Director, Alex Sundakov, Castalia now has over 40 professional staff and has offices in Washington DC, USA; New York, USA; Paris, France; Sydney, Australia; Wellington, New Zealand; and Bogota, Colombia.
