Dieter was born in Germany, and worked for smaller accounting firms in the resort town of Garmisch, before joining the Munich office of KPMG. He transferred to KPMG Sacramento in 2002. He then worked as a tax manager with Ernst & Young for several years, assisting multi state and publicly traded corporations, partnerships and their owners. During his time with two of the "Big 4" international accounting firms he was able to gain thorough knowledge and experience in the fields of accounting, individual, partnership and corporate taxation. In February of 2008 Dieter became the owner of Homer, Stenger & Company, and enjoys working with individuals and businesses in Auburn, as well as the greater Tahoe, Sacramento, the San Francisco Bay Area, and Mexico.
When he is not working, Dieter spends as much time as possible with his family, but also enjoys running, road biking, and working on his (of course German) classic cars.
