Patti Grayson was born in Thunder Bay, moved to Atikokan, Ontario at age 8, and wrote her first foolscap collection of stories that same year. After graduating high school as an Ontario Scholar, she attended the University of Western Ontario and the University of Winnipeg where she studied English and Theatre.

After a brief stint as a bank teller, she landed a job at CKY Television writing commercials, got married, and moved to the copy department of Sears Advertising, where she wrote and produced print, tv and radio ads. While working as the Copy Chief for Sears, she began hankering for her roots in theatre. She returned to her acting studies and began auditioning for theatre companies. In 1985, she made the leap and performed in her first independent professional stage show. That year, she was hired by the Manitoba Puppet Theatre where she worked and toured several shows. During those years, and for many afterward, she also had numerous small roles in television and film.

In 1988, Patti became a stay-at-home mom, and writing became the creative outlet of choice. She began studying again, this time focussing on poetry and fiction writing. She took numerous courses, attended workshops, joined a writer's group, earned an apprentice position in the Manitoba Writers' Guild Mentor Program and received a Writer's Grant from the Manitoba Arts Council. Her first book, Core Samples, was published in 2004 by Turnstone Press. She then started working part-time as a school librarian while completing her first novel, Autumn, One Spring, published in 2010. In 2015, Patti's first juvenile/YA book, Ghost Most Foul, was released by Coteau Books.

Patti feels very blessed to be focussing her energy on creative endeavours at present, including her current adult novel-in-progress. The Twistical Nature of Spoons is due out fall of 2023 with Turnstone Press.
