I worked with Longbourn on an extremely complex project, and I am still in awe of the impressive project management and meticulous editing I saw consistently throughout. Their work was high-quality, prompt, and executed with the utmost of care; I cannot recommend Longbourn enthusiastically enough.

Tess Stevens

Senior Academic Designer, StudySync

As an online company producing more than 400 pages of new content each month, we rely on the editing and writing expertise of Longbourn Editorial Services to help ensure the excellence of all our finished products. In the eight years they have worked with us, we have been consistently satisfied and impressed with their work in all areas of writing and editing and would recommend them without reservation.   

Nancy Ewald

Chief Content Officer and Founder, ActivityConnection.com

As the editor of a small press, I rely heavily on outside vendors to help me address all facets of product development and production. When Longbourn is on one of my projects, I can depend on that work being completed reliably, well, and on time.

Larry Marotta

Executive Editor, APH Press

Hiring Susie was like cloning myself. She and her team did the quality of work I’d have done if I’d had the time. The work she and her team did was meticulous and did not require the rework that is common with many vendors. Longbourn is the best I have ever worked with.

Beth Sundermeyer Van Houten

Associate Academic Designer, McGraw-Hill Education

Longbourn Editorial Services has been a standard for us for quite some time. We can always count on their accuracy and also their honest assessment of tasks and timelines. That is extremely important. I don’t want a group that says they can do anything and then under delivers. I want a group that I can trust. When they say they can complete something, I know I can count on them to be on time, thorough, and accurate.

Amy Burrows-McCabe

Director of Product Management, Literacy Acceleration, McGraw Hill Education

McGraw-Hill Education has partnered with Longbourn Editorial on a range of projects for a variety of services–writing, editing, proofreading, and developing correlations to national and state standards.
