Calliope Consulting


For over twenty years, we have been helping organizations and individuals produce and publish professional, error-free work.  Calliope is owned and operated by David Logan and Joanna Beth Tweedy.  Calliope's editors and consultants have advanced degrees, and our services are confidential.

Please note: Because we have ongoing relationships with many of our clients, we must be highly selective about the work we accept.  Referrals are given special consideration, so if you have been referred by one of our clients, please mention that in your inquiry.


We edit and proofread content for business clients and individuals, including global organizations and multilingual writers.  We work most frequently with businesses, NGOs, doctoral candidates, scholars, and researchers.  We also offer instructional guidance and services for multilingual writers. 


In addition to editorial and proofreading services, on occasion (and for certain clients), we will create copy, including web content, marketing materials, professional correspondence, and speeches.  We do not write papers for students.
