Our successful challenges have resulted in millions of dollars of property tax savings for our clients.

We have an A+ rating with the Better Business Bureau.

No reduction. No fee! There’s no charge for our services unless we successfully reduce your tax assessment. If a Small Claims Assessment Review appeal is filed, there is only a court-imposed filing fee (currently $30).

Our knowledgeable and dedicated team has hundreds of years of cumulative experience in the business.

We are customer-service oriented and focused on achieving positive results. In the process, we are happy to educate taxpayers on how the Nassau County property tax assessment system works.

We are pioneers in residential property tax reduction. We continue to stay ahead of our competitors with state-of-the art technology that helps us evaluate the potential for reducing your assessment.

We choose you. We do not market to every homeowner. We conduct a preliminary analysis to determine whether we believe we can obtain a tax reduction on your behalf before we contact you.

We represent you. Once you authorize us to file a grievance on your behalf, we will appear at all conferences and hearings relating to your property tax matter. We’ll take care of every aspect from beginning to end.

We protect your privacy. All client information is confidential. We do not share your personal home data to market to others.

No surprises. There are no hidden fees buried in our agreement with you. Other companies have hidden fees, expenses and penalty clauses. We do not.

We give back to our community by supporting many charitable causes and events in Nassau County.

You have done a great job for us over the years lowering our assessment.

Maidenbaum has saved me a tremendous amount …. I’m a big fan and give out their number to all my buyers and sellers!!

Avi D.

I have used Maidenbaum for about 10 years now and I received reductions probably 5 out of the 10 years including the last 3 in a row. I recommend them highly.

Rick E.

First time I’m using them. I got good recommendations about them. I grieve my taxes myself every year. Not this time. I decided that I’d use Maidenbaum. Now it’s time for the Big Guns.

Marie B.

The best service in town!!! Thank you.

Tim P.

Have been using Maidenbaum for years and love the service we get from them. Ask for Carol when you call, she is wonderful to deal with. All of the staff is terrific, but Carol is particularly helpful.

Anne K.

I have hired Maidenbaum for many years. They always have done right by me and have saved me thousands. I highly recommend them.

Douglas A.

They’re the best Mine lowered each year. This time they said don’t fight it as it’s as low as it could be right now. I listen as I said they’re terrific!

Dave T.

We have had Maidenbaum successfully grieve our taxes many, many times. You have nothing to lose!

- Joseph M.

You guys are the best!

- Ray O.

I thank Maidenbaum & yourself with helping me. The average person will not be able to for the most part get things right. Especially the older person ‘like me.’ Professionals know the ins & outs. I leave it to them. Once again THANK YOU.

- Jim A.

I thank God every day that we have you to help us with our tax grievances.

- Michael P.

Thank you very much as always for your caring, efficiency and positive results. You are a wonderful company comprised of great people. Thanks again!!!

- David W.

This is very helpful and because of your transparency I want you to know that we have retained your services once again.

- Guti

Thank you both for your expertise/professionalism.

- Zenaida R.

I greatly appreciate you getting back to me. My issue with [competitor info removed] is they have never responded to me regarding the status. I just keep getting generic automated emails to sign up with them again. Would you resign when nobody can even tell you hey we are working on it? I want to give you guys a shot. Your email to me is more than I have gotten from them in 2 years. And you being very honest about the length of the process, telling me you will update me quarterly and not taking down [competitor info removed] in the process says a lot. So thank you again. And please just keep me updated. That’s all I ask.

- Claudine T.

Too often people go unrecognized for the great work they do…I thank you for taking on the burden of fighting the battle.

- Michael P.

Thank you for getting back to me. I am very pleased with the outcome!

– Maureen D.

Thanks for the quick reply. I appreciate all of your help!

– Patrick G.

Best regard to everyone in your office that made my tax cut possible.

– Costas M.

You rock, thanks for the quick response!

– Rob T.

I am writing to inform you of the wonderful and informative service I have received. As a result of my experience, I have referred numerous friends to you.

- Esmeralda R.

I recently had your company grieve some property taxes of mine. I wanted to tell you how happy I was that your team was not only successful, they were a pleasure to deal with.

– Jeannine R.

I want to tell you how impressed I am that an actual person picks up the phone when I call. It’s refreshing to talk to a live person and not get caught up in a voice mail system. Please don’t ever change that! In a world where people are so quick to complain and many times you get an attitude from an employee, I felt it was important to tell you how professional and pleasant your staff was to me.

– Theresa O.

Thank you for explaining my recent bill, you are always patient and explain the whole process very well. I recently referred a colleague.

– Wayne Z.

I use this opportunity to say thanks.  This is much appreciated and you can be sure I will continue to use your services.

– Joseph L.
