Meet the Sagebrush Coffee 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. This business is run by the people below, but it exists because of the selfless contribution of many unnamed friends and family members that keep giving their time to help us grow.
Matt Kellso
Sagebrush Coffee Owner:
I started this business as a way to subsidize my coffee roasting hobby in 2012. I combined my love of coffee with my background in web design, marketing, and Industrial Engineering to try to make an online coffee roasting business happen. I was born at University of Michigan hospital (bleeding blue), but spent my childhood in South Carolina. When I was about 10, I moved to Tempe, and have lived within a few miles of that home ever since. I love the east valley but hate the heat, which makes the summers a test of patience. I graduated from Arizona State University with an Industrial Engineering degree and spent the first decade of my career at Intel doing anything from process improvement projects to forecasting to RFID consulting. Moving on from there I spent the next 15 years at Spencer's TV & Appliance doing much of the same things. In April of 2020 I finally stepped away to focus on Sagebrush full-time. After we learned to manage the rush of online orders that COVID brought, we moved to a larger production facility and focused on opening our coffee shop.The last few years have also given me an opportunity to nurture international relationships in sourcing our coffees. I love the coffee industry, I love the community of local shops, the camaraderie of local micro-communities of a single shop, learning and educating on the industry. But nothing brings me more joy in my work than talking to a farmer about their coffee and how our little business in Chandler is thriving because they’ve dedicated their life to the pit of a coffee cherry. When I’m not at Sagebrush I’m probably meeting with someone from our Church (Grace Bible Church in Tempe) where I’m a pastor, reading or vacationing with family which includes exploring coffee shops.
Office & Production Team
You may not see this group at the coffee shop, but they're very much involved in everything you see at Sagebrush.

He is also plugged into his church and plays bass on the worship team. In his free time, he loves going out with his wife, Diana to new restaurants. He and Diana also run an online vintage clothing store called Nosy Ghost Vintage and spend the majority of their downtime photographing new pieces, writing descriptions, and sourcing new clothing.

Zoë became a part of the Sagebrush team in 2016 where she took on the role of lead packager and office manager.

In Janna's mind, quality coffee and sustainability go hand in hand. Her love of specialty coffee roasting developed at a young age, when her parents got into the coffee industry themselves.

She previously worked as an outdoor camp educator, a seasonal grassland bird research technician, and now enjoys learning about Arizona’s biodiversity while developing her skills as a barista! In her free time, she loves birdwatching, playing cello, and getting into crafts or puzzles. Janna is fascinated by every aspect of coffee cultivation, and loves getting to work with a team that highlights the producers behind each amazing cup of coffee.
