About Us
Hi, my name is Tessa Underwood, and I'm a ProAdvisor Certified Bookkeeper in Galt, CA, just outside of Sacramento. I've been working with QuickBooks for the past 16 years, specializing in the construction and service industries.
Working with my sister Marriah to provide business owners with the tools they need to grow has been immensely rewarding and fulfilling. We are able to work together to utilize the latest in cloud technology to provide exceptional bookkeeping service to small businesses all over the county.
I have a passion for hiking and exploring our National Parks, but I also love painting, reading, and working in my garden at home.
I currently live in Galt, CA with my incredible entrepreneurial husband and our five spirited children, who always keep me on my toes with their endless adventures.
Marriah Haag
Hi, I’m Marriah Haag, and I’m a QuickBooks and Payroll Certified Bookkeeper based in Bountiful, UT, just outside of Salt Lake City. I’ve spent the past three years working with QuickBooks, including overseeing a team of accountants managing the books for over 40 doctors’ offices.
Today, I work alongside my sister Tessa, helping small businesses and families across Utah and California take control of their finances with confidence. Partnering with Tessa has been a natural fit—her passion for supporting entrepreneurs inspired me to join forces and build something meaningful together.
When I’m not working, you’ll usually find me cooking or baking something fun! I love a good book—usually via audiobook these days—and I cherish time spent with my husband, our three kids, and our Tibetan Mastiff, Odin. We especially love camping adventures in Moab and Zion.
