Soil Cycle Board Members


Caitlyn Lewis


Chair of the Board/

Executive Director

Caitlyn believes that difficult issues, like food waste, require unique solutions that often involve entire communities and sometimes...even bicycles! People are immensely powerful especially when they come together around a common cause. One of her main goals is to push her community to think about their food and the natural cycle of life a little differently.

Madson Matthias 


Community Outreach

Everything Madison does is driven by a passionate cultivation of the relationship between people and places — employing radical problem solving, biomimicry, and community engagement wherever possible. She has lived in North America, Europe, and Asia, studying the variations of people’s needs and wants for the environments they inhabit and traverse. Her most profound experiences have been her exposures to biomimicry, and the Dutch integration of bicycles into urban environments and their application of landscape architecture. 

Madison graduated in 2020 with a Bachelor of Arts in Geography and Environmental Design from the University of Colorado at Boulder. During her studies she researched the intersection of cognitive empathy and green infrastructure. Her sustainability skillset is diverse, including experience in LEED green building, GIS and spatial analysis, transportation and municipal planning, placemaking, and zero waste projects. 

With her enthusiasm for building the capacity of the public through education, Madison is excited to be working with Soil Cycle to build individual empowerment to contribute to combating climate change.

Therese Robbins


Vice President / Permaculture and Garden Coordinator

Therese 'Trez" Robbins is a long-time Soil Cycle volunteer, and now enthusiastic board member. Her passions include plant medicine, sustainable agriculture, permaculture design, and making delicious food. She is the garden designer at the new Soil Cycle space, filling it with medicinal and edible flowers, fruits, and vegetables to encourage and inspire a love for growing things, clean the air and soil, and educate everyone on the myriad benefits of each plant there. She is so excited to be a part of reducing food waste and cultivating healthy soil in Missoula!

Alison Coluccio


Compost Expert

Alison is a long-time plant geek who still heeds the advice she got from a mentor gardener who, when asked what to do about weeds in the garden said, "Eat them!" Alison grew up on a family farm and as part of a culture where everyone had a compost pile. She became a Master Composter through Cornell's Cooperative Extension in 2012 and was a regular volunteer in Ithaca, NY before relocating to Missoula. She was happy to find Soil Cycle as a way to keep bears out of her home compost and she's very excited to learn about the plants of Montana, particularly which ones she can eat.

Thomas Bassett


Treasurer/ Operations Manager

When Thomas isn't busy composting food scraps at Soil Cycle, he is the lead designer of the 18.5 yard hot compost bin system and completing other carpentry projects at the Soil Cycle site. He is dedicated to keeping Soil Cycle as sustainable as possible and upcycling Soil Cycle's food waste back into food. He spends his free time baking cakes, cookies, danishes, and other treats.

Rachel was one of the first Soil Cycle subscribers and she has been an avid supporter ever since (can you say worm casings and compost tea?!). Rachel has a background in international higher education and she loves sustainable transportation, playing outside in the dirt, and always strives to make her community a better place. She's excited to support, nurture, and grow this organization through her role as the board secretary.
