GrieveItNowNassau County property tax grievanceBack homeGrieveItNow is a Nassau County property tax grievance service operated by LI Grievance Services LLC and founded by brothers Chris and Stephen Ambrosio.
The business started with a real homeowner grievance and one simple idea: homeowners should be able to challenge an assessment without giving up a large share of the savings.
GrieveItNow combines institutional financial experience with first-hand homeowner grievance experience — and keeps the process personal.
A Certified Public Accountant with over 13 years of financial experience. Chris spent more than six years at a Big Four accounting firm auditing financial services companies, followed by a year in private equity and nearly six years in the real estate industry as a Senior Manager of Accounting.
He brings disciplined financial analysis, documentation, and review to GrieveItNow's property tax grievance process.
Stephen filed his own Suffolk County property tax grievance after buying his first home in Northport and won a $1,411-per-year reduction. That experience became the starting point for GrieveItNow.
Today, Stephen helps manage the grievance process end to end, including property research, comparable-sales analysis, client authorization, Nassau County ARC filing preparation, and client updates.
Stephen bought his first home in Northport, filed a Suffolk County property tax grievance, and won — saving $1,411 a year.
When he looked around, he realized many homeowners did not understand the grievance process or know they could challenge their assessment. He called his brother Chris, and they built GrieveItNow.
One principle was there from the start: Long Island homeowners should not have to give up a large percentage of their savings just to pursue a fair assessment. GrieveItNow uses a flat-fee model with no percentage-of-savings charge and no automatic renewal.
Some grievance firms use percentage-of-savings pricing. At a 50% first-year contingency fee, a $2,000 annual reduction would mean a $1,000 fee; a $3,000 reduction would mean a $1,500 fee.
GrieveItNow charges a flat fee instead. If your assessment is reduced, you keep the resulting tax savings rather than sharing them with us.
We charge one flat $99 fee for research, preparation, and Nassau County grievance filing. We do not take a percentage of your savings.
We built the service to remove confusion, reduce paperwork friction, and keep communication straightforward from intake through updates.
The active service is focused on Nassau County so the experience, messaging, and filing process remain tightly aligned to the homeowners we are serving.
