Eagle Scout

Community

In addition to building quality homes, we value giving back to our community. We are pleased to have helped several young men achieve their Eagle Scout Awards, as well as to have provided supplies and donations for other scouting, baseball and soccer organizations. We have also supported local fire companies, breast cancer walks, and a charity that works to alleviate homelessness and poverty.

In 1989 we signed a contract with Jim to build our home in Green Lane Manor. He said to us, “Have fun with this, there will be problems, but we will work them out”.  That was the start of a friendship that has lasted over 30 years.
