Alison has been featured in articles in Sunset Magazine, New York Times and Landscape Architecture and has won several ‘Excellence in Landscape’ awards from the Associated Landscape Contractors of Colorado-ALCC. She received the ALCC 2008 ‘Person of the Year’ award for her work researching and promoting sustainable landscaping.

Office Team

Lynn, Matt and Jennifer make up our office team, as Plant coordinator, Estimator, and Bookkeeper respectively. Lynn procures and takes care of the plants, making sure orders and deliveries are up to spec. She’s had a love for plants all of her life. Matt uses his love of plants and mathematics to craft accurate estimates and construction documents for our installation team. He’s been interested in landscaping since he was “knee-high to a grasshopper.” Jennifer, born and raised here in Boulder, has worked for Matrix for over 20 years. She always adds a touch of humor to the number-crunching! They make sure the plants are healthy, the jobs come in as estimated and that the employees are happy.

Carly Harrison, Cultivation Lead

Carly's passion for plants and the natural world began as a young child but truly blossomed when she moved to Colorado from New England to attend an Herbal Medicine certification program. From there she began her 18 year-long career in Horticulture, Permaculture, Professional Gardening, Horticulture Management, Garden & Seasonal Container Design and most recently Interior Floral Design. She enjoys the mountain lifestyle, residing outside of Nederland with her furry four-legged companion, Ella Bear.
