Peter Atkins and Mary Ann Henry

Peter Atkins and Associates is an ecological and organic landscape architecture contractor.

From master planning through construction and meticulous long-term Organic maintenance management, our experience and creativity transform outdoor spaces with experts in each realm.

Each detail of our landscape design, construction, and maintenance services is carefully planned and discussed with you ahead of time to match your budget, timeline, and expectations. Whether we are masterminding a multi-phase installation that encompasses every corner of your property or simply maintaining your perennial borders, you can expect nothing but top value, hard work, consistency and respect for your property and home from the entire team.

Peter Atkins and Associates  is dedicated to expanding the beauty in your hometown while working with nature to preserve and protect the natural resources of our area. We use native plants and well-adapted plants. We choose plants that are drought-tolerant, insect-resistant, hearty, and manageable. We choose plant that will support the pollinator for bees, butterflies and birds. We work with Nature always.

Client appreciated the design teams enthusiasm to solve design dilemmas such as drainage, tired landscapes, and  poor maintenance standards.   Another important feature of having a landscape design, is the ability to project into the future, and formulate a budget, over time. It is no secret that any home or property improvement is an expense. Having a landscape design plan gives the client the opportunity to achieve their goals, over a period of time, controlling their own budget, yet being able to achieve their ultimate goal. All in a well thought out order to maximize efficiency and cost savings.

We are enormously proud to be a completely accredited organic land care (NOFA) business since 2010. We use no synthetic fertilizers or chemical imputes on any of our property that we maintain. This protects your children, pets, drinking water, soil, the environment, and mother earth.

We also offer organic lawn care,  Plant Health Care and Soil Management Services. Our approach responds to the larger environmental challenges we face with climate change, water shortage/quality and recycling with sustainability.

When you work with Peter Atkins and Mary Ann Henry,  We will become your garden advocate. We will be your single contact person within Peter Atkins and Associates who will be your local landscape partner.

Peter Atkins and Mary Ann Henry are the eyes and ears behind our business. We keep the communications channel with our company simple with direct communication which is consistent and informative. At the conclusion of all daily work an email is sent to you sharing what was completed that day and what is planned for the next visits. This is also a time to keep the communication channel focused on you.

We would like to become your landscape management partner.

Jean Galle, Landscape Architect

  • Jean’s love of nature started as a child in Ohio. Long walks in the woods looking for wildflowers with her father taught her valuable lessons.
  • The desire to become a professional Landscape designer came when Jean heard about sustainable green roofs and the positive effects for cities and the environment. Jean graduated 1st in her class at Columbia University’s Master’s of Landscape Design.
  • Shortly after she received a Flower Garden Design certificate from New York Botanical Garden.
  • Her gardens designs are unique with the play of line, form and texture with many details – design knowledge gained from her 2 former successful careers – that of a ballet dance and fashion designer. Jean’s designs match the site, keeping the clients desires in mind with infusions of color, year around interest and a bit of surprise and whimsy. Native plants are used when possible and the environment and pollinators are always concerned. Besides designing for Peter, Jean has her own clients in New York City and New Jersey Shore and freelances for other NYC based landscape companies. Peter and I met at the New York Botanical Garden and the rest is history.
