​​Our Values 

To serve small- and home-based business owners and help them maximize all the legitimate tax deductions available to them, increasing their bottom line and resulting in the best possible outcome.

Faith, Family, Finances. 
Integrity matters.
Justice should prevail. 
Service above self. 
Honesty is a given. 
Humility is a gift. 
Accuracy is a must. 

I was audited on my very first tax return at the tender age of 19 because I tried to exercise my right to deduct expenses from my cottage business. From that experience, I vowed to never be audited again.  I took the classes and have been preparing my own tax returns ever since.  


Years later at a downturn in the economy, friends asked me to lend my expertise and help them with their tax returns, and I have been preparing returns professionally since 2002, starting with Jackson Hewitt and Liberty Tax, and eventually founding United Tax Service independently in 2009.


​I'm a local girl born and raised in Orange County, so this is where my office is located, but I have clients from as far away as Oregon, Texas, and Wisconsin.
