 Trustindex verifies that the original source of the review is Google. I used Number Nerds after finding all the great reviews on Google and loving the name of the company. They are an absolutely phenomenal company that I highly recommend. From my first call to ask them about doing my taxes, to meeting online with Avi, to getting my taxes filed, the entire thing was an extremely smooth process. They were extremely compassionate and understanding about my situation. They kept me updated with regular emails through the customer portal, so I always knew what was going on. Uploading all my tax documents was really easy and Avi made sure that I was aware they were available to me should any questions arise. I can't say enough good things about Number Nerds. If you need tax preparation, use them. Highly, highly recommended.

She has gone above and beyond every step of the way. We are a small account for her but we're treated like her top client. She is extremely smart, responsive, and easy to work with. Thank you Avi for doing such an awesome job!
