STONE VALLEY CONSTRUCTION HISTORY Marie Porter DeVinney, President of Stone Valley Construction Inc., in Pine Grove Mills, can't rightly claim she still has the first dollar she ever made as an independent businesswoman. She can, however, produce a copy of the check she received after her company completed its first job. "We did some plumbing work for a guy in State College," she recalls. "We didn't even have our own equipment, we had to rent a backhoe to get the job done. Things went smoothly, though. Here we are, 20 years later, still in business." Stone Valley Construction began in 1980, operating out of rented space with just three employees, all partners in the business: Marie Porter DeVinney, Vice-President Robert "Skinny" King and Secretary/Treasurer Harry "Whitey" Glenny. Now the company has its own shop in Pine Grove Mills as well as satellite locations in Huntingdon and Oceola Mills (all well equipped) and boasts a roster of 95 workers.
