About Teresa Nolan Barensfeld

I have a BS in mathematics and computer science, summa cum laude. When I began editing and proofreading in 1991, I specialized in my college-major fields, then expanded into various subjects, including STEM (science, technology, engineering, mathematics), the social sciences, political science, and others. I have since added fact checking and project management to the services I offer. I love editing because I learn something new every day and help authors convey their ideas clearly and effectively. Before my editing career, I worked as a computer analyst for Morgan Stanley, a business manager for a woodworking company, a tax preparer, and a designer-sewist.

I am a long-time member of the Editorial Freelancers Association (EFA); I am currently the coleader of the EFA’s Upper Hudson chapter and have served as a member-at-large on the EFA Board of Trustees and a speaker at various chapter meetings. I am also a member of ACES (American Copy Editors Society). Outside of editing, I serve on my town’s Parks and Recreation Committee. In my spare time, I enjoy using my sewing and design skills to create quilts, apparel, and other textile arts.

“I have been very pleased with Teresa's copyediting on two journals on which I work. She is very conscientious and meticulous. She raises relevant queries and suggestions and keeps a style sheet, which she regularly updates. Her language skills are excellent. Teresa also has a very pleasant personality and is easy to work with.”

Madeline Friedman

“You did a great job. I was particularly appreciative of your questions to me during the process. A key one was whether I wanted to de-personalize the text or leave it casual. I chose the latter and it is clear now that was the best choice. Perhaps another copyeditor would have just gone ahead and changed it without even asking.”
