Tammy Schuiling
Managing Director This email address is being protected from spambots. You need JavaScript enabled to view it.
Tammy joins the ITI after a long career in marketing & communications. Although a performer at heart, Tammy prefers to be behind the scenes and has used her marketing skills to create awareness, fundraise and lobby support for various arts and culture organizations. Her rare combination of creative and strategic approach has garnered numerous marketing awards, which she hopes will be beneficial for the iTi. When not spending time with her "tribe" of artistic friends, she likes to walk her rescue dog, eat/cook/write about food, and is reigniting her love of painting, writing and photography. Tammy is based in Calgary, Canada and loves to travel to far away places - especially if a music festival is involved. She's looking forward to connecting with the global iTi tribe of improvisors.
Tammy will oversee the general operations of the ITI on a part-time basis.
