About Green Theory
A local company built to raise the standard.
Founded by Zavary Isner while he was still a Mt. Lebanon High School student, the company grew by pairing a student-led work ethic with results that consistently exceeded expectations.
Today, Green Theory brings that same accountability to residential and commercial properties across the South Hills—from routine maintenance to detailed landscape improvements.

Property care that looks considered.
Choose a one-time project or build a maintenance plan around the way you want your property to look throughout the year.
Ideas shaped for your property
Landscape Design
Walk the property with us, share what you want it to become, and leave with a clear plan for the details that make an outdoor space feel complete.
Clean beds, lasting protection
Mulching
A smooth, even layer of mulch that helps beds retain moisture, suppress weeds, and look finished in spring, fall, or both.
More than mow and blow
Grass Maintenance
Each visit includes mowing, trimming edges, clearing hard surfaces, and a final property check so the whole yard looks cared for.
Right plants, thoughtfully placed
Planting
From helping with the heavy work to selecting and installing plants for you, we tailor the project to how involved you want to be.
Shape, health, and fullness
Trimming & Pruning
Clean, sharp tools and careful cuts keep bushes and small trees attractive while supporting healthy, full growth.
Selected work
Landscaping that turns heads.
Real Green Theory projects across Pittsburgh's South Hills—clean lines, healthier beds, and properties that feel finished.
How it works

A note from the founder
“I started Local Students Lawn and Landscaping after my tenth-grade year. The goal was simple: work hard, emphasize that we were students, and surprise people with the quality. Today, I still take great pride in caring for South Hills properties through Green Theory while pursuing mechanical engineering.”
