Irvine & Company was founded in 1984 by Jack Irvine.  Debbie Degener joined Jack in managing and guiding the firm in 1990.  Their vision was to create a client-centric accounting firm where clients could get the level of attention and industry expertise that they needed. While Irvine and Company is now known as an expert in many industries, its initial expertise was rooted in the Oregon wine industry, where even today we service over 250 winery and vineyard clients.  Jack retired in 2015.  Before retiring in 2021, Debbie led the firm as managing partner for over 20 years and establish the firm’s niche in the distilling industry.

Our firm celebrates our history, founders, lasting partnerships with this region’s greatest makers, creators, and entrepreneurs, and for the contributed excellence and growth in the future.
