John Duston has been thorough, thoughtful, and communicative about our tax returns for several years. He's handled everything from our usual W2s to investment real estate, refinances, primary home purchases and more complicated stock options with ESSPs, RSUs, and ISOs. There is a lot of attention to detail and personalized solutions and suggestions for our household.

Our Expertise

We're most familiar with California tax laws, but luckily most other states have less complicated laws-- so we can cover a lot of territory. Whether you have a property in the Mid-West or a business in California, we can very likely help you. We know how to file returns for just about anybody, from simple personal returns to growing businesses running payroll for hundreds of employees.

Our Philosophy

One size does NOT fit all. No two people, businesses, or investors are the same, so why assume that their goals will be? No matter how simple or complex your tax return is, you deserve someone who understands the ins-and-outs of your situation. We can help you achieve your goals, whatever they are.

Our Commitment

It's very important to us to have a relationship with our clients. We want to know about you-- your situation, obstacles, and goals. We want to ensure that you're getting what you need out of your CPA. If you're unsure whether we're a good fit for you, just give us a call-- we can at least answer some of your questions. If you're not 100% satisfied with our services, we guarantee your money back!
