  Bill Melvin – Owner, Managing Director

Bill is a graduate of the University of Colorado’s School of Environmental Design in Boulder where he focused on landscape architecture. He has been a certified Permaculture Designer since 1997, has extensive experience working the land for over 2 decades as a landscaper, organic farmer, forester, and in outdoor education. And since 2000 Bill has been owner of Ecoscape, working with his clients to create landscape that are not only beautiful, but appropriate for our region.

Bill hails from the Hudson River Valley of New York. As a young man Bill was enticed by the mountains of Colorado where he relocated to in the late 80’s, and truly discovered the wonders of nature. Bill shares his passion for our native flora, edible and medicinal landscaping, and ecological land management through his teachings, locally and beyond. He has been an adjunct faculty member of Naropa University, has taught workshops at the Denver Botanic Gardens, and through local non- profit organizations.

When not working, Bill spends much of his time playing in the outdoors of Colorado with his wife Jen and son Daniel. Whenever possible he loves to escape to the hills for skiing, biking, hiking, and mushroom hunting forays. His extensive travels around the country and the world keep him in search of inspiring natural wonders and culinary delights!

  Andrew Mehlhorn Haller – Landscape Manager

As an avid outdoorsman, Andrew acquired an appreciation for working with the land. From Ohio to New Zealand to England, he has honed his skills working as an apprentice to master craftsmen and applying his leadership as foreman and project manager of a wide array of landscape projects. His skills are welcomed here at Ecoscape where he continues to learn our local flora while creating lovely, sustainable landscapes.

Andrew lives with his wife, Janka (pronounced Yan-ka), kindergardener Eliyah, and new baby Lake,  in Coal Creek Canyon. He thoroughly enjoys reading, dreaming up and working on projects for their new mountain home, watching stimulating films, eating nutritious and delicious home-cooked meals, and tending to their animals (including goats, chickens, cats and a great white Pyrenees who goes by the name of Dakota). Andrew also sits on the Boulder Symphony board of directors and is their ‘Mozart’ mascot.

  Sue Rigdon – Landscape Design & Botany

Sue inherited an adventurous spirit and love of nature from her parents and traveled extensively as a child throughout the US and overseas giving her a broad appreciation of diverse cultures and ecosystems. During a brief stay in Boulder, she fell in love with the surrounding beauty and Colorado lifestyle and decided to call it home, raising two daughters with her photographer/musician husband.

Sue has a Bachelor’s degree in Botany from the University of Washington, Seattle, and studied in the Master’s program of Architecture & Landscape Architecture at the University of Colorado, Denver. Additional years of experience in related fields allow her to create naturally beautiful and sustainable outdoor spaces.  She enjoys working with clients to create personalized landscapes that meet their specific needs using plant material with pleasing layers of color, texture and form that change with the seasons.

Sue is at her happiest hiking, tending plants and designing landscapes. She also loves travel, books, quirky ceramics, sitting in sunbeams and black & white photography. Her own gardens have been featured in Boulder’s Eccentric Artists Garden tour and are examples of water-wise planting.

Lisa Sangelo, PLA – Landscape Architect

Lisa received her degree in Landscape Architecture with honors from the University of Western Australia, having studied fine arts, arid-land horticulture, permaculture design, and travelling extensively.  After working in conservation and land and visual resource management, Lisa moved to the Front Range in 1999, and is a licensed Landscape Architect in the State of Colorado.

Lisa is fascinated by the interface between people and the natural landscape and believes that a ‘sense of place’ has significant impact on quality of life.  She strives to listen and communicate effectively and to understand each site well in order to design uniquely appropriate landscapes. In the high, dry plains and foothills of Colorado, she knows that a sustainable approach, far from compromising design intent, adds to the meaning and enjoyability of the place.

In her words, after working in the local design build industry for more than 15 years, Lisa ‘came home’ to the Ecoscape team this year.  When not scheming the land, Lisa loves time with her teenage boys, being in community, playing the banjo and making art.

Chris Tracy – Landscape Designer

Chris Tracy has been working in the Green Industry since 2007. From commercial to residential, he has experience in numerous aspects of landscape installation, maintenance, and design. He graduated in May of 2014 from Colorado State University receiving a Bachelor’s degree in Environmental Horticulture with concentrations in Landscape Design and Contracting and Landscape Business, which included a Business Minor.

He strives to bring out the best of any outdoor space; big or small, formal or natural, day or night. He enjoys working with clients to meet their specific needs and give them the most value in their outdoor spaces.

When Chris isn’t busy drawing up new landscapes, he enjoys getting away from the big cities like the ones he grew up in Washington State. Whether that means he’s taking his family camping, exploring the beautiful Colorado Mountains on his motorcycle, or just finding a quiet place to sit and think, the mountains have always been his escape.

Linda Martens – Plants & Design

Ecoscape is excited to bring on-board long-time horticulturist & Master Gardener, Linda Martens. Originally from the Chicago area, Linda set roots in Colorado in 1976. Since then she has worked many years in the floral industry and for several of Boulder’s premier landscape design firms. She describes herself as a ‘total plant geek’ and studied art and horticulture in college. Linda is the mother of Emily and Andy Martens, both of which have worked for Ecoscape’s maintenance and installation teams in past years.

She will also be offering a new service with us: container plantings for your entryways, patios, and decks. Stay tuned for more details or call to schedule a site visit!


Ryan Spinharney – Ecological Land Management

Ryan started out in Omaha, NE in his early teens pushing a lawn mower around the neighborhood looking for mowing clients. He quickly was picked up by a local landscaper and began working with small residential installs. In the mid 90’s he was hired on to an interior/exterior landscaping firm and began attending college for Botany and Horticulture. In 1997 Ryan took a snowboarding trip to Colorado and decided that Colorado would soon become home. In 1999 he moved out to Boulder and started an interior landscaping company. Specializing in commercial and residential clients, Ryan’s company developed a great list of interior clients where they primarily designed, installed and maintained interiors with tropical plants and living walls.

After 18 years as a small business owner and 10 years as a sustainable landscaper/edible gardener, he decided to scale-back his business and team up with other ecological landscapers in Boulder county. In 2016 Ryan finished a Permaculture design course in Beaverton, OR where low impact agriculture, sustainable ecology, soil restoration, botany studies and permaculture were all a part of the curriculum. Ryan is the father of five children, enjoys spending time on his half-acre farm, is a music lover, and has the ongoing curiosity that makes him a lifelong learner.

  Richard Matteson – CGCS, Irrigation Specialist

Richard began his career in Turfgrass Management in 1976 working at the Virginia Tech Golf Course. He moved to Oregon in 1980 and became the golf course superintendent at Michaelbook Golf Club in McMinnville in 1983. Richard returned to college to complete his degree in Horticulture at Oregon State University in 1996. After graduation he became the Pendleton Country Club GC superintendent. In 1998 he became a certified golf course superintendent through GCSAA.

Richard moved to Colorado in 2008 to work for the City of Fort Morgan and then accepted the position of golf course superintendent for the county of Los Alamos, NM. In 2014 he retired from the golf course industry, moved back to Colorado, and now uses his vast irrigation experience in the residential landscape arena. Richard has many years of experience with large operational budgets, turf management, managing employees & equipment, and is constantly evolving his knowledge on water-wise irrigation technology and pollinator habitats.

Karina Zedalis – Business Development & Operational Logistics

Growing up with a lush Florida jungle and bayou in the backyard, Karina Zedalis discovered early on, the cyclical nature of tides, trees as yardsticks of time, and that seeds hold the future in really small packages. Endless lawn mowing and helping her mom with a huge indoor tropical plant collection, would lead Karina to have a deep love for the soil and horticulture.

Eightteen years ago, Karina traded the sea for the mountains and began her own journey of parenthood with a home birth and a baby named Bianca. When her daughter was school age, she was recruited to be the campus director for a new start-up elementary based on contemplative education in Boulder. During her tenure with Eastern Sun Academy she got involved with the study of permaculture as a method of conscious design. For the last four years she has been an environmental sales consultant for Global Organic soil amendments, helping many Front Range school districts, golf courses, and parks districts, manage their turf grass more sustainably while revitalizing their soil for optimal plant performance.

Karina Zedalis graduated from Florida State University with a BS in Textiles and Marketing, and earned a Permaculture Design Certificate in 2009. Since the passage of Amendment 64, she has been actively involved in educating and advocating for the building of a local Colorado industrial hemp economy with a focus on using hemp in horticulture, for nutrition, and with soil remediation. When not fawning over plants, you can find Karina doing yoga, cooking, reading, or creating paintings with lots of color. However if it’s nice outside, she’ll be working on her mountain property: fetching firewood, tending wildflowers, and dreaming up ways to outsmart the local ground squirrels.
