Desiree Tillie, Director – Desiree joined AVWS in May 2019 as a volunteer tour guide, and joined the Board of Directors a year later in May 2020. She has a BA in Economics. Desiree retired in 2018 after more than 30 years as a Senior Buyer, Product Development Manager and Brand Manager for major retailers. Her career took her all over the world sourcing and developing exciting, and innovative products. The place that always drew her back, and which remains her favourite place in the world, is right here, in Muskoka. Because the extensive travel took her away from home for so much of the year, she was never able to give back to the community she now calls home. Connecting with AVWS has allowed her to find new passion in her second career as Tour Coordinator and as a Board member. Her extensive skill set of relationship building, negotiation, collaborative communication and mentoring, along with strong organizational and analytical skills are readily transferable to the new challenges of volunteering at Aspen. As one of the front-line volunteers, it her hope to continue to educate the public about the surrounding wildlife and wildlife interactions with humans.
