To practice responsible land stewardship through thoughtful and beautiful ecological landscape design.

Our Vision

We believe the great outdoors are essential to the human experience, and our designs invite your interaction with nature. By reconnecting with the natural world, we hope to inspire reverence and protection of our soils, waterways, air, and abundant biodiversity, while reducing toxic exposures and personal stress. We encourage you to seek wildness in your own backyard!

Our Core Values

In all of our work, we uphold our core values of honesty, integrity, knowledge, creativity, innovation and communication.

Our Promise - Ecological Landscape Design


In all of our work, we follow organic standards set by the Northeast Organic Farming Association (NOFA). GJL never uses synthetic pesticides, fertilizers, herbicides or insecticides. These traditionally applied toxic chemicals persist in the environment, runoff into our waterways, and compromise the health of families, pets, wildlife, and soil biology.


Stormwater management is essential for water conservation. By capturing and cleaning stormwater on site through rain gardens and bio-retention, we can recharge our aquifers instead of perpetuating runoff, water pollution, and erosion.


Healthy soil = Happy plants! We care for the soil by fostering microbial communities that help plants uptake nutrients. Synthetic chemicals kill microbes and are never used in our work. Instead we use natural fertilizers like shredded leaves, grass clippings, and compost to feed microbial decomposers that, in turn, make nutrients available to plants.


Much of our wild habitats have been compromised by development and we are currently experiencing a great loss of biodiversity. At GJL, we think every landscape is an opportunity to provide habitat and support biodiversity. Many of our properties are NWF Certified Wildlife Habitats that provide food, water and shelter for local fauna. Imagine the joy of a buzzing pollinator garden frequented by butterflies and migrating birds!


Selecting a majority of native plants ensures that we support the local fauna that evolved alongside the flora. Native plants are also hardy in our climate and require fewer inputs, watering, and maintenance. By selecting native, we also do not risk importing alien pests or diseases that can knock out defenseless natives and disrupt ecosystems.


Tackling emissions is hugely important for our planet’s future. Luckily, plants are one of nature’s best carbon-capture systems. Plants secrete CO2 through photosynthesis, and the microbial exchange stores it in the soil as a “carbon sink.” One of the easiest ways to lower your carbon footprint is to plant more plants! GJL is also working towards an all-electric conversion of our landscape equipment to further reduce our emissions footprint.
