About Us

Proud to say we are a family owned small buisness since our creation and plan on staying that way for years to come. Currently ran by me and my son, Mark Cox Jr.

We started off as just a simple landscaping company with just handling garden and lawn care back in 1979. Over the past 40 years serving the Southern Maryland area we have evolved into a larger and more diverse company adding exterior design, sewage tank removal to our already gold standard services.
