Steven V. Greso President

Steven was hired by Group Four Engineers/Surveyors in 1978. With great mentors, Steven worked on some of the most spectacular projects in the Puget Sound region. These beautiful lots and acreage all needed on-site sewage disposal systems.

When not working on a septic tank task, Steven is a local musician playing French Horn with local groups at various venues around Puget Sound. Daughter Selina is a Juilliard graduate.
