John is a long time supporter of the local arts, but if not found in the audience of a fine concert, jazz club or ballet, he might be tooling around on his John Deere tractor or flying Trilby kites on the Washington coast.

The uncommon combination of a liberal arts degree and professional studies in business and information technologies provides the basis for the blend of creativity, innovation and technical prowess John brings to Roth Hill and its clients.

A native Seattle "east-sider," John earned his BA in Music from Western Washington University and is an accomplished bassist and composer/arranger. Work and play is managed around his most important role as a full-time husband and dad.
