Rebekah Kramer, CPA is a partner in Brotemarkle Davis & Co. specializing in assurance services and business consulting.   She is originally from Napa, California and is a Justin-Sienna High School alumnus. She is a graduate of Concordia University, Irvine where she majored in Business Administration with a dual emphasis in Marketing and Accounting.  She spent three years working for a Southern California accounting firm before returning to the Napa Valley. While she may not find many opportunities to apply her SoCal yacht-counting expertise (she once had to count yachts docked in ports from San Diego to Newport), her diverse audit skills honed from working with customers in Oil and Gas, Manufacturing, and Real Estate are a big plus. Rebekah first stretched her entrepreneurial muscles when she founded a chapter of co-ed business fraternity, Delta Sigma Pi, at Concordia. She hopes to apply what she learned not only to her role as an auditor but also to some day opening an animal shelter. When she is not busy auditing, you might find Rebekah exploring a new trail or revisiting one of her favorite national parks – Denali in Alaska.  Rebekah is a CPA licensed by the California Board of Accountancy.
