  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 her adventurous spirit and love of nature from her parents and has traveled extensively giving her a broad appreciation for diverse cultures and ecosystems. During a brief stay in Boulder, she fell in love with the Colorado lifestyle and surrounding beauty and made it her  home, raising two amazing daughters with her photographer/musician husband.

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 has a Bachelors degree in Botany from the University of Washington, Seattle, and studied in the Masters 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.

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.

Donal ‘Cheval’ Oldaker – Landscape Designer

Cheval hails from Charlottesville, Virginia. He received his degree in Landscape Architecture from the University of Maryland in 2011. Originally Cheval grew up wild-n-free as a child in the rolling hills of the Maryland horse country. This is where he became deeply aware of the importance of our ecological impact and concerns while living in the Chesapeake Bay watershed.

While based in the classics, he is forward thinking in using creativity in his design approach. Cheval incorporates years of environmental knowledge, design, the fluidity of a dancer and the unexpected revelation of the theatre to his landscapes. He is always looking for ways to incorporate these teachings to designing outdoor spaces that feel like a sacred place. Cheval brings this holistic view to the table every day, and in everything he does.

A passionate outdoorsman on on and off horses, he has shared and taught riding and movement in a wide range of environments from the Nevada’s Great Basin, top of the mountains of the Blue Ridge, to the beaches of the Pacific Northwest Coast.

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.

Linda will join our botanist, Sue Rigdon, in providing additional plant expertise to our landscape design work and maintenance teams. 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!

John Aguilar – Landscape Maintenance Division Manager

John Aguilar, a Colorado native, has been in the Green Industry since 1995. Starting with an entry-level position in turf maintenance, he worked his way up through the ranks, season after season. At the City of Westminister, his responsibilities grew to managing crews, problem solving for the Parks Department, and running light and heavy machinery.

John made a big jump in 2004, when he became a large construction Superintendent for Urban Farmer. He oversaw crews of 20 plus people, installing over $25 million dollars in commercial landscape. John branched out to working in the residential landscape market a few years later, discovering that client interactions and account management paired well with his industry experience. In his 20 plus year career, John has handled work in irrigation, hardscape construction, plant installations, snow removal management, and has a deep understanding of cultural practices for turf management in the Front Range.  His dedication to creating and maintaining beautiful landscapes can be seen in the passion he brings to his work and by inspiring his teams.

In his spare time, John volunteers as a youth basketball and baseball coach, for both of his sons’ teams (one in middle school, one in high school).   On weekends, you can find John and his wife working on their own outdoor living space!

  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.

Eighteen 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.

CJ Carpenter – Landscape Installation Foreman

Colton ‘CJ’ Carpenter is originally from Alamosa, CO.  He came to work for Ecoscape with experience from Healthy Forest Mitigation Services in Lyons.  He started out with our installation crew almost 3 years ago, and has grown into a skillful foreman.  CJ can run a variety of earth-moving equipment with ease and dexterity.  Same goes for snowplowing, where CJ often puts in long hours removing snow from our clients’ neighborhoods west of Boulder.

CJ and his wife Samantha, have recently purchased their first home, and have two active puppies that keep them busy between home improvement projects!  Their first child, a little girl, was born April 9, 2019.


Jose’ Felix – Landscape Installation Foreman

Jose’ Felix has worked in the landscape construction industry, for well over ten years here in the Front Range, and has been with Ecoscape since 2017.  He brings a solid masonry skill-set to every project and has a kind-hearted spirit and a keen eye for detail.  Jose’ and his wife and children live in Longmont.




 Tosh Todorov – Landscape Installation Foreman

The entity that we call “Tosh” first came to us about a year ago. It claimed to be a man who had immigrated to the United States 15 years ago from Eastern Europe, Bulgaria to be exact. We soon found out that this was just a cover to hide ‘Its’ true identity. As it turns out, Tosh (we’re still not sure if Tosh has a gender but we refer to him as a ‘he’) is an alien from a parallel dimension who came to our reality because he wanted to experience life on Earth.

Tosh showed quite an interest in terrestrial plants, rocks, animals and other natural elements, and seemed to understand how they interact and relate to each other. We decided to give him a job as one of our landscaping foremen here at Ecoscape, and see how things play out. He seems to be very keen on promoting a vision of sustainability and harmony with nature.

There is still a lot we don’t know about Tosh, but we do know that he eats tons of bananas, he loves water, and he seems to have mastered the English language well (although if you listen, you’ll definitely notice some kind of an odd alien accent here and there).
