About Titan
Long Island’s Most Trusted Appraiser!
With hundreds of satisfied clients and tons of 5 star online reviews, Annmarie Giovanniello and Titan Appraisals will go the extra mile to make it happen.
Titan Appraisals, Inc. is a boutique, owner-operated residential appraisal firm serving Long Island for over 20 years. Led by Annmarie Giovanniello, a Certified Residential Appraiser with more than 5,000 appraisals to her credit, Titan specializes in the properties that are hardest to value – luxury estates, waterfront homes, custom builds, and complex properties throughout Nassau, Suffolk, and the Hamptons.
When you work with Titan Appraisals, you work directly with Annmarie. Not a junior appraiser, not a rotating staff. That’s intentional. Our clients are paying for 20 years of judgment, local knowledge, and discretion – and that’s exactly what they get.
Long Island is not a single market. It’s dozens of micro-markets layered on top of each other – each neighborhood, each waterfront block, each Hamptons hamlet with its own pricing logic, its own buyer pool, its own unwritten rules. Getting a valuation right here means knowing those layers. It means having walked through enough homes in enough neighborhoods over enough years that the number you arrive at isn’t just defensible, it’s true.
That’s what we bring to every appraisal. Not a formula. Not an algorithm. A trained eye and two decades of showing up.
Hi, I’m Annmarie
I am Annmarie Giovanniello – and I took the long way here.
I have a master’s degree in both English Literature and Library & Information Sciences. I spent years as a high school English teacher and librarian before I walked away from a tenured position to follow something that felt more like me. I got my certified appraiser’s license in 2006, then my real estate license – and I built this business through the worst possible timing. When the 2008 mortgage crisis hit, the appraisal industry collapsed along with everything else. Appraisers were leaving in droves. I stayed, put my head down, and kept building. In 2010, I opened Titan Appraisals. That decision turned out to be one of the best I ever made.
What teaching gave me, and what I carry into every appraisal, is the ability to take something complex and make it clear. To read a situation carefully. To communicate findings in a way that actually makes sense to the person sitting across from me, whether that’s a homeowner, an attorney, or a judge.
What twenty years of appraisal work gave me is something harder to explain and impossible to shortcut: the judgment that only comes from showing up, property after property, market shift after market shift, until the numbers stop being numbers and start telling you a story.
I built this business on Long Island. I know these markets the way you know a neighborhood you’ve lived in for decades – not just the streets, but the rhythms.
When accuracy matters, and the stakes are real, that’s where I do my best work.
