    Jeff has worked on a wide variety of projects, from seismic upgrades of historic structures to complex and eye-catching, athletic facilities, since joining KPFF in 2004. Jeff particularly enjoys providing construction engineering support to contractors, developing simple and efficient methods for completing projects with complex construction logistics. As a carpenter, Jeff learned firsthand about putting things together – experience he brings to every project and to the wood committee at KPFF. He has been an integral engineer for many projects. He provided support for the erection of the Evergreen Wings and Waves Water Park in McMinnville OR, which included a mobile, two-crane lifting operation that placed a Boeing 747 on the roof of the partially competed building structure.
