ROHO, Inc. was incorporated in 1973 by Robert H. Graebe. He began his career as an electrical engineer, but while working on a project for a hospital, he became concerned about a means to heal ischemic ulcers or pressures sores, as they are commonly called. Through intense research and development, Mr. Graebe invented ROHO DRY FLOATATION technology.
While originally organized into three separate companies, in March 2001 the Boards of Directors of ROHO, Inc., ROHO International, and CROWN THERAPEUTICS, Inc. announced a new corporate structure, The ROHO Group, which provided a more effective approach to global business. This new structure allowed for greater synergy and efficiencies throughout all functions of the three organizations by consolidating important support departments such as marketing, training, education, and corporate planning. Under The ROHO Group, the sales, marketing, and product development functions have been focused upon the three distinct market segments of medical seating, support surfaces, and consumer products (non-medical applications).
