Elevating Outdoor Living: The Art and Expertise Behind GP Landscape Design

For over 27 years, GP Landscape Design has redefined what it means to care for and transform outdoor spaces. Far beyond simple lawn maintenance, the company specializes in creating custom, design-forward landscapes that blend beauty, function, and craftsmanship—tailored to each client’s vision and lifestyle.

From elegant plantings to complete outdoor makeovers, GP handles everything in-house: retaining walls, paver patios, pool surrounds, outdoor kitchens, fireplaces, and full-scale outdoor living environments. “We love backyard pool projects—the possibilities are endless,” says founder Greg Picca. “It’s where people gather and memories are made. Watching a property evolve and seeing that ‘wow’ moment from a homeowner is incredibly rewarding.”

Design Expertise Meets Construction Precision
GP offers comprehensive services including hardscape and pool design, 3D renderings, landscape lighting, project management, plant healthcare (including tick and mosquito control), drainage solutions, and commercial snow management. Whether it’s for a private estate or a sophisticated residential build, every project is backed by a collaborative team with decades of combined experience.

Greg Picca brings both passion and professionalism to the business. A 2004 graduate of NYIT with a degree in Architecture and a concentration in construction management, Greg developed his appreciation for masonry at an early age while working alongside his late father. “Being hands-on helps you understand every layer of the work—it gives you respect for the process and the people who make it happen.”

The GP team includes General Manager Joe Walsh, Project Manager Roric Walter, Senior Account Manager Bob Mitterando, and office coordinators Jeannie and Amber. Together, the leadership team represents more than 75 years of experience in the green industry. Greg’s wife Deb, a former business owner herself, has also joined the company, bringing organizational efficiency to office operations.

Full-Service. Trusted. Local.
Headquartered in Center Moriches, where the Picca family also lives, GP Landscape Design is proud to be a trusted local business. With over 22 vehicles on the road each day, their signature green-fendered trucks have become a familiar sight across the community.

Clients trust GP not only for their professionalism and results—but for their ability to handle all aspects of exterior design and maintenance under one roof. “We’ve even gotten calls for raccoons in attics,” laughs Greg. “We didn’t handle it ourselves—but we have reliable partners for just about everything.”

Why Experience Matters
The landscape industry may seem accessible, but not all providers deliver lasting value. In an era where service and experience matter more than ever, GP Landscape Design stands apart for its longevity, client loyalty, and results-driven approach. Referrals, repeat business, and word-of-mouth are the foundation of the company’s continued success.
