Schwafel in 1946; Bissell & Karn in 1982, Greiner in 1990; and in 1995 the firm was established as Robert A. Karn & Associates, Inc. Currently under new ownership, Justin Petrini, PE is the principal engineer, along with the addition of Gene Petrini who has over 40-year experience in Land development and Construction, throughout Northern California.
