Erica Umphreyville has always been surrounded by numbers and accountants—from her parents to her siblings—but her true passion lies in making a meaningful impact on her community and for her clients. A graduate of Southern Methodist University in Dallas, Texas, Erica holds a Master of Science in Accounting. She honed her expertise at a Big 4 CPA firm, focusing on the governmental and non-profit sectors, and more recently served as a Controller, overseeing the financial operations of 24 Title I charter schools. Erica’s deep connection to her work is inspired by the powerful women in her life, especially her mother, who rose from an Accounts Payable Manager to a Director of Finance in the Biotech industry, embodying the hard work and dedication that Erica values. Though based in Texas, Erica is excited to work with wineries, leveraging her unique blend of analytical prowess and creative problem-solving to unravel complex accounting challenges and help clients achieve their goals. When she’s not delving into data or strategizing with clients, you might find Erica appreciating nature, whether it’s walking on a trail near her apartment or engaging in a competitive game of pickleball. She also enjoys exploring her culinary side, cooking Italian food, and growing her own herb and vegetable garden. Erica is a CPA, licensed by the Texas State Board of Public Accountancy

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.
