Kathryn Macintosh was born in Montréal but spent her formative years in New Brunswick and Nova Scotia. She attended Acadia University and the University of Toronto, where she majored in trombone performance under Gordon Sweeney. She enjoyed further studies with Dennis Miller and Pierre Beaudry of the Orchestre symphonique de Montréal, and masterclasses at the Banff Centre and Domaine Forget.
While in her early twenties Kathryn joined the Edmonton Symphony. She has also appeared with the Kitchener-Waterloo Symphony, the Hamilton Philharmonic, the Calgary Philharmonic, and the Saskatoon Symphony.
Ever since her arrival in Edmonton, Kathryn has been active in various chamber music projects, and was instrumental in the establishment of the Mill Creek Colliery Band. Kathryn is founder and artistic director of the C'mon (Chamber music old & new) Festival which will celebrate its fifth year in July 2017. The festival seeks to draw new audiences to classical music in Edmonton with a casual atmosphere and adventurous, genre-blurring programming.
An avid cyclist, Kathryn can be seen year-round, commuting around town with her trombone on her back.
