A few words from some of our trusted clients.

Dina Bushrod Recommends O’Conor & Associates

They have lowered my taxes every year since I signed up with them (around 5years). This cost is very reasonable and is based on a set percentage of the money saved. They are easy to contact and have a newsletter filled with information on saving money on your property taxes as well as step by step procedures on how to do it yourself. They do automatically protest yearly tax, unless you notify in writing and in timely fashion, that you no longer require their services. I receive every year a notice from them stating they will be protesting unless notification is given not to. I’m waiting to see how they do, as property taxes have really taken a leap.

If you are Pat O’Connor, You have been very helpful to I and my partner. Thank you so much. You give dates of when the deadline to these outrageous property taxes appeals are. You tell us about taxpayer liaison officer and so much more. I could not be more appreciative and thank you again.

O’Connor is the real deal. I signed up with them 8 years ago with no regrets. They protest my property taxes every year and save me money. My experience has been 100% positive. Definitely recommended!

Sharon W. Houston, TX

I have been using O’Connor since 2015, and they have been saving me almost every year. If they can’t save me then no fees are charged. This year they saved me over $18k and that is a savings of over $500 in taxes, therefore I only had to pay them half of that which was $263. I did not have the time or energy to do all the paper work and leg work. Wh I see some areas in my home that needs repairing, I send pics to O’Connor.

Brian Adams Recommends O’Connor & Associates.

Great Work. The team has been protesting on my property behalf for over two years now. They are very professional and proactive. Returns have been satisfactory. I’m thankful.
