About Cohasset Natural
Rooted in Sustainability. Driven by Service.
Cohasset Natural was created with a clear mission: to offer the South Shore a cleaner, quieter, truly eco-friendly alternative to traditional landscaping. We use 100% electric equipment, native plants, and sustainable methods to create outdoor spaces that are healthier for your home and the planet.
Seth Tweeddale
Seth Tweeddale spent 27 years in the investment world, but his passion always lived outdoors. As a kid, he ran a small landscaping business before he even turned ten. As an adult, he was the friend who relaxed by raking, pruning, or planting something new.
Matt O’Connor
Matt O’Connor brings more than 15 years of landscape maintenance experience to the Cohasset Natural team, following an earlier career in finance. His expertise spans hardscaping, hydroseeding, full lawn and irrigation installations, and ongoing lawn care.
Both Seth and Matt recognized how outdated and harmful traditional lawn-care practices had become. After discovering that a single hour of a gas-powered blower emits as much pollution as a 1,100-mile car trip, they felt compelled to offer the South Shore a cleaner, more responsible option. Their combined landscaping expertise, ongoing education, and commitment to high-level service now guide every aspect of Cohasset Natural’s eco-forward approach.
✔ Zero Emissions, Zero Noise Hassle: Electric equipment that’s up to 70% quieter than gas.
✔ Native & Organic: Healthier soil, smarter irrigation, and regionally sourced plants.
✔ White-Glove Service: A4 commitment to reliability and communication that reflects Seth’s front-office background.
✔ Community First: Proud caretaker of public gardens at the Cohasset Swim Center and Deer Hill Elementary.
