The genesis of Halstatt began with Barron Gift Collier, an early 20th-century advertising magnate and one of the most influential figures in the development of Florida. Founded by his granddaughter, Judy Sproul, Halstatt is the female-led investment and operational arm of the Sproul family that has grown from the master developer of the renowned Grey Oaks Country Club in Naples, FL, and the redevelopment of LaPlaya Beach and Golf Resort, into a sophisticated alternative investment platform that deploys capital on behalf of the Sproul family and third-party institutional investors.
