We have a showroom in the fashion district of downtown Los Angeles, contrary to the lower market value, the property tax has keep rising every year. So, we felt it must be unfair, but after doing a business with AOPTA, it changed to be so fair. In 2023, we received the refund check from LA county with the amount of about $20,000 after an appeal by AOPTA. This firm analyzes well about the fair market value of the real estate and knows well how to pursue the county assessor for the tax deduction. AOPTA is working on another tax appeal for the same location in 2024. Finally, I strongly recommend you work with AOPTA to save a lot of tax expense.

Completely stress free experience; Anthony prepared for me at the time that I have high stress level, after effect of global Covid, at work. Much as I need to dedicate time to prepare for the hearing, he did all the analysis and guided me on what I need to submit to him. We got a reduction that was very much needed.

We were planning to fight this ourselves, but Anthony reached out to us with a great strategy. He was prompt, professional, and very communicative. I’d hire him again.

AOPTA contacted us regarding our appeal and took over and handled it expertly and got us the highest refund possible. I would recommend them to anyone submitting an appeal to the property tax department.

I’m delighted to share my experience with Anthony O'Connor and his team at AOPTA. They provided exceptional service and helped the assisted living facility in contesting our property taxes. In the wake of the pandemic, the facility was struggling to keep up with expenses, and property taxes were one of the most significant concerns. Anthony and his team took on the daunting task of contesting the property taxes and worked tirelessly to secure a successful reduction. Throughout the process, Anthony and his team were professional, knowledgeable, and supportive. They communicated with us regularly, answered all our questions, and made sure we understood every step of the process. Thanks to their expertise, we were able to reduce our property taxes, which helped us save a significant amount of money. I would highly recommend Anthony and his team at AOPTA to anyone looking for property tax experts. They are simply the best in the business!

So glad we connected with Anthony at AOPTA after buying a property that got assessed over purchase price. Anthony managed to save us about $4000 a year in taxes as the county ended up assessing the value at a lower and reasonable price. I definitely recommend AOPTA! Thank you
