From the Robert L. Sipe Inc. website, accessed Oct 31, 2015 —

Robert Sipe builds organs "advocating a return to 17th and 18th-century design concepts. Among these principles are low wind pressure, slider wind chests, mechanical key action, the integrity of each separate division housed in the main organ case, and the case itself 'standing high and free...' Following this classical design appropriate to the traditional polyphonic literature for the organ, Sipe organs also incorporate certain modifications to meet requirements of many 19th and 20th-century compositions"

From the OHS PC Database —

After the partnership of Sipes-Yarbough ended, Robert Sipes established his own firm as Robert L. Sipes, Inc. in Dallas, Texas in 1965. He began representing Aeolian-Skinner in Texas in 1968. By 1969 he had accepted an offer with Aeolian-Skinner and closed his Texas firm to move to Randolph, Massachusetts. When Aeolian-Skinner closed in 1972, he returned to Texas and re-established his own firm under the previous name. The firm is active as of 2015.
