Kate Gregory grew up in Colorado and began playing classical violin at the age of six, but in college she started learning to play Irish fiddle and fell in love with traditional music. She met her fiddle teacher, Boulder-based fiddler Adam Agee, when she had completely put down her violin, feeling frustrated with the rigidity of classical performance. Learning to play traditional music unleashed new creativity and her life took a path of exploring different types of trad, playing at local sessions, performing with various music collaborators, and going to fiddle camps from California to Sweden. At fiddle camps especially, she found a love of American Old Time music and further developed her Old Time playing under the direction of Natalie Padilla. Today, her playing is inspired by her classical background and the numerous fiddle traditions she loves, culminating in a creative and rhythmic playing style. 

Kate now lives in Portland, OR, where she teaches fiddle and is part of several musical projects, including the Irish band Kate and the Lads and her duo with multi-instrumentalist Baron Collins-Hill. Her other main project is with Brooklyn based cellist Brendan Hearn; they had their debut at the Boston Celtic Music Festival in January of 2023. With these projects she has performed up and down the Pacific Northwest, including at the Bellingham Celtic Festival and the Mt. Vernon Highland Games. She has also been featured on the Old Time podcast Get Up in the Cool hosted by banjo player Cameron DeWhitt.

When not playing music, she is a Geographic Information Systems and Environmental Justice researcher and practitioner. In June of 2023 she received her Master of Science in Geography from Portland State University where she researched inequity in urban greenspace. In her spare time Kate loves being outside, skiing, cooking, crafting, and especially being with friends.
