Below is a partial list of companies served. Services include speech, business plan and Private Placement Memorandum writing, communication coaching, and continued education credit courses in business communication.

The largest client segments are entrepreneurs seeking investment, and investment bankers desiring business writing services because Great Communications is supervised by a professional business writer with Series 24, 63 and 7 licenses.
