John founded Turnstone in 1997 after traveling for years building zoo exhibits around the country. John enjoys researching the geology and history of the features and ecosystems the company replicates, and building structures that will endure. The time he spends in the backcountry and his travels inform and inspire his work.
Heidi wears many hats at Turnstone. She is our main point of contact at the office, working on contracts and invoicing, insurance, safety, and beyond for our team and clients. She is a chef and loves the outdoors. In her spare time, you will find her whipping something up in the kitchen, running or hiking. You might also find her watching a movie with some cake and/or ice cream in hand.
