Tilly’s mission is to make professional landscape design accessible to every homeowner.

Sarah, Heather, Blythe, Alexis

Tilly was founded by four high school friends from the suburbs of Chicago who are now scattered across the country with ten kids between them! Inspired by Tilly’s mission, Sarah Finazzo, Heather Hoeppner, Alexis Sutton and Blythe Yost took their long-distance friendships to the next level by founding the company in 2019.

The Tilly design team is led by Blythe Yost, who has been practicing landscape architecture for over 15 years. She is the principal and founder of two high-end landscape companies, whose projects include everything from contemporary courtyards in Brooklyn to multi-acre estates in The Hamptons. Yost graduated from Cornell University with a Bachelor of Landscape Architecture and a focus on horticulture.
