• Two years experience as an editor for Investopedia's Advisor Insights, including editing for content, fact-checking and improving the overall readability of advisor-submitted articles.
  • Editor of several books and doctoral papers, including three fiction books, one non-fiction book, and one memoir.


Mary Hall graduated from college with her English degree, but without a clear path to using it. She spent some time as a legal assistant, then several more years as a litigation paralegal with an intellectual property firm in Chicago.

Her position as a project manager in the educational testing division of Houghton Mifflin Harcourt solidified her desire to write or edit as a career. With the birth of her daughter, Mary left her full-time job but continued to work as a freelance editor for HMH and began blogging for a few law firms.

After a three-and-a-half-year stint as a content creator and marketer with a logistics company, during which she won the Cincinnati American Marketing Association’s Marketing Department of One Award, she returned to freelancing. Since then, she has handled blogging and social media for a financial advisory firm, written content for various small businesses, edited several books for independent authors and doctoral papers for PhD students, became the senior content strategist for UniMedia—an inbound marketing firm—and continues to edit hundreds of articles for Investopedia each year.


Mary received her bachelor's in English from Kent State University with a business minor and writing concentration.

Quote from Mary Hall

"Not being a numbers person myself, I truly enjoy editing articles to make them accessible to readers who most likely did not major in finance, but are interested in educating themselves about financial planning and investing in their futures."
