Susan McKenzie

Susan McKenzie

Soprano, Susan McKenzie, is a lifelong performer whose experience spans the globe. Through her own travels and performance opportunities, Susan experienced first-hand the struggles of creating the brand and awareness she needed on a sustainable budget. This inspired her to launch Artistic Marketing, a marketing agency that specializes in working with performers – both as individuals and in groups. Susan’s marketing experience ranges from digital marketing, print marketing, and graphic design, to event planning and more specific campaigns. With nearly a decade of experience in arts marketing, Susan is renowned for her ability to create effective strategic plans and impactful marketing campaigns for performers of all walks of life.

Susan currently resides in Greeley, Colorado, where she attended the University of Northern Colorado. She holds a Bachelor’s in Music Education with an emphasis in Voice and a Masters in Business Administration. While she never anticipated staying in Greeley, she fell in love with the rich arts culture the city had to offer, and decided to make it her home. Susan has always had a passion for music, enjoying how music is a universal language that has the power to pull a room full of complete strangers together to share something beautifully profound. She finds her joy in sharing this passion with others, which is why she has dedicated much of her time to supporting nonprofits in the arts industry. When she is not doing something with the arts, she enjoys playing with her dog, Paxton, spending time at the lake or in the mountains, and is teaching herself photography.
