Meet the Sagebrush Team

Sagebrush Coffee is a small roastery with a lot of help. What's missing from this list are countless hours of friends giving advice and support and buying those bags of coffee when we weren't really a business yet. This business is run by the people below, but it exists because of the selfless contribution of many unnamed friends and family members that just keep giving their time to help us grow.

Sarah Young

Production Manager / Head Roaster

Sarah joined the Sagebrush team in October of 2019 as our Production Lead and is now our Head Roaster as well. She was born in Torrance, California, but moved to the valley when she was just 3 years old. She lives in Gilbert and loves it. She has worked with kids before for many years and is also a certified nail technician. Coffee is a constant companion and drinking it is one of her favorite hobbies. If she isn’t drinking coffee, she loves spending time with her friends, reading books, or doing anything that involves Disney!
