The Rolf Institute of Structural Integration is the official institution of the postural approach called “Rolfing,” developed by Ida P. Rolf. Rolf founded the institute in 1971, and it is located in Boulder, CO. Its website offers information on Rolfing as well as a comprehensive catalogue of certified Rolfers through a search function, if you can’t attend classes at the Institute itself in Colorado. (Note: there are more Rolfers than will appear on the RSI site, however; the site displays practitioners who have paid to be advertised there.)
