A family landscaping tradition
Mr. Mike built the business one job at a time.
Long before today's trucks and equipment, Mr. Mike set a simple example for the family: work hard, be honest with people and earn the next job by taking care of the one in front of you.

After the Korean War, Michael O'Sullivan, known to everyone as Mr. Mike, laid the foundation for the family landscaping business.
He built the business client by client. People knew him for his integrity and the quality of his work. At home, Robert's mother raised ten children with the same determination. In the O'Sullivan household, hard work was not something people talked about. It was simply how things got done.
Robert brought those standards into the company that has served the Main Line and Delaware, Montgomery and Chester Counties since 1984. Today, the crew handles everything from weekly lawn care to grading, clearing and hardscape installations for residential, commercial, public and industrial clients.
What happens next
A straightforward way to plan the work.
You do not need to diagnose the property before getting in touch. Start with what you are seeing, and the details can be worked through in order.
Tell us what needs attention
A phone call or short email with the town and the problem is enough to begin.
Look at the whole job
The property, access, drainage, materials and timing all help shape the right approach.
Make the scope clear
The estimate sets out the work being discussed and the details that affect it.
Plan the work
Once the scope is agreed, the job can be scheduled around the site, season and weather.
Keep the property cared for
Seasonal or annual maintenance can continue the relationship when ongoing care makes sense.
A project that meant something
Helping bring the Knotted Grotto to life
In 2015, Robert and his crew worked with Meg Saligman Studios, Project HOME, Steam Chamber, Starlite Productions and people with lived experience of homelessness on a temporary Philadelphia installation for the papal visit.




Visitors wrote down a personal struggle or prayer, then exchanged it for one left by somebody else. The installation drew attention to hunger, homelessness and the burdens people carry. Project HOME later used thousands of those prayers in the permanent Knotted Home installation.
