Meline McWhirter, Enrolled Agent

Matriarch of the Mothership

With a formal education in Environmental Engineering and Advanced Mathematics, Meline is not your average accountant. She just happens to be particularly great with numbers, but passionate people are her passion. She got her "accidental" start more than 25 years ago, which led her to launching Natural Numbers in 2003. "While bookkeeping and tax preparation are important and inevitable, one cannot live on numbers alone." Behind the scenes and outside of office hours, Meline is regularly found off-grid, adventure motorcycle camping in the varied, remote and less-populated landscapes of Southern California. Sharing delicious food from her garden and kitchen with her family and friends is core to her sense of connecting with the people she cares about most.

Tina Grant, Tax Preparer

Confusion Counter-Agent

Tina's first job was selling avocados and oranges on her family's Southern California farm. After college she returned to the farm to manage the retail operation. She later moved on to residential real estate sales, earning a master's degree in spatial analysis along the way. As a real estate agent for many years Tina specialized in guiding buyers through the perilous waters of first-time home ownership. Like it did for many people, the pandemic precipitated a career change. Tina realized her affinities for number-crunching and parsing dense contracts would be put to good use as a tax preparer. When she's not heads down in a return or working on improving Natural Numbers' internal processes, Tina can be found hiking the San Diego County mountains, enjoying a beer by the water or visiting her kids, who live much too far away. Tina is a California Registered Tax Preparer and is studying for the SEE exam to become an Enrolled Agent.
