Who this is for

This page is for property managers, commercial owners, institutions, general contractors looking for a veteran-owned subcontractor, and contracting officers who found the company through SAM.gov. The company is owned by Rathana Yen, who served in the U.S. Marine Corps from 2008 to 2017 and left as a Sergeant. It is based in Lower Merion Township, Montgomery County.

One crew does the design, grading, stone, planting, carpentry and maintenance. For a site manager that means one point of contact and one company answerable for the result, from the first walk-through to the last cleanup. There is no hand-off between a hardscape sub and a planting sub, and no question about who owns a problem. Estimates are free, written, and answered in one to two business days. Registration and identification details are listed below.
