Kari M. Costamagna

Kari joined Bowman in 2009 and is Principal in the Firm. Initially coming on board as a Staff Accountant, she has worked diligently for the firm over the past 15 years, serving as Senior, Supervisor, Manager and Sr. Manager before taking on her current role as Principal. Kari specializes in accounting, audit and tax services for affordable housing projects, construction industry, not-for-profit entities, and nonpublic closely-held businesses. Kari holds a B.S. in Business with a concentration in Accounting and Finance from the University of the Pacific.

Kari is known for being an authentic and approachable colleague. Her favorite quote is, “Enjoy the little things in life, for one day you may look back and realize they were the big things.” Even with an easygoing nature, Kari is still a hard worker and a team player who credits her success to the support of her parents, her husband, and Bowman Partner Tobbie Wells, a mentor in her career.


Kari and her husband, Andrew, were born and raised in Lodi, where they raise their young son, Anthony. Outside the office, Kari enjoys all that Lodi has to offer – wineries, breweries, Lodi Lake, farmer’s markets, and more. When not out around town, she likes hosting BBQs with family and friends at their country house, poolside.
