Jeff Ward

General Manager

Jeff joined the LOC in 2007 at a time when the organization had outgrown its current management structure. Jeff provided continuity and a single point of contact for lake residents and Board members, while providing clear guidance on staff priorities. This has proved to be invaluable as the lake has become more desirable and a popular address for Lake Oswego residents. Jeff has a love of music and animals, and can often be seen serenading his mules and dogs with his bluegrass guitar chops.
