Williamsport is where it all began in 1986, with Ken Larson’s dream to create an A/E firm that would provide central PA with professional engineering services and reliable careers for people in the surrounding communities. This office provides the full spectrum of architecture, engineering, and GIS services to clients nationwide. Our Williamsport staff actively give back to their communities, volunteering for technical, professional, and non-profit organizations to enrich the communities we serve. As our national presence continues to grow, we’re committed to bringing Ken’s vision of client service excellence, community stewardship, and personal and career development to our offices nationwide.
