Her areas of garden expertise include: organic gardening, high-elevation gardening, fruit trees, native plants of the Southern Colorado Plateau, herbal medicine, and plant pathology. In her free time, Ansley enjoys rock climbing, backpacking, biking, kayaking, traditional archery, and, of course, gardening.

Alex started off as a cashier in 2014 and has risen to our Indoor Manager for a few seasons now. She is known as the houseplant expert here and also has quite a knack for merchandising!

Caitlin Thomas, Retail Operations Specialist
Caitlin has worked on our administrative side of the nursery for two and a half years. She obtained a degree in sustainable agriculture from Berea College in 2014 and has an obsession with organization, which makes her good at behind-the-scenes nursery operations. Outside of making sure your nursery experience goes smoothly, she likes to tend to her own garden, take close-ups of native pollinators, and recreate in the outdoors in almost every way imaginable.

Megan Mills, Head Cashier
Megan is our Head Cashier and stand-in Coffee Shoppe Manager, although she is cross-trained in all departments. She is from Phoenix originally but has lived in Flagstaff for roughly 10 years. She has a bachelor’s degree in Psychology and Art History. Megan is knowledgeable about houseplants and organic veggie gardening. She is passionate about playing music, continuing her education, traveling, mountain biking, and spending time with loved ones. Megan is an avid museum-goer, and she absolutely adores contemporary art.

Bradley Foster, Yard Foreman
Brad is our yard foreman, cinder driver, part-time snow-shoveler and also does plant and deliveries occasionally. He moved here from Alaska with his wife Amanda. They recently welcomed their newest member of the family, their 6 month old daughter, Amelya. When he is not working, he hangs out at home with his family and mimics the dinosaur sounds Amelya makes. When they can, they enjoy going camping, fishing, hiking and sometimes hunting.

Amanda Zarzoa-Foster
Amanda moved here from Alaska in November 2016 to help start Dottie’s Coffee Shoppe. Amanda can’t live without coffee and has worked in various barista jobs over the years. She has been the integral resource for starting and managing Dottie’s and also works in the indoor department. This past August, she began maternity leave with her new baby, Amelya – now you can find her (and sweet little Amelya!) helping out in the office. Amanda loves houseplants and dabbled in a small fruit and veggie garden on her deck this past summer. She loves exploring the outdoors, traveling, and reading.
