New York State Licensed Land Surveyor No. 50762
Where the property line ends, the evidence begins.
Practicing since 1998, Frank S. Ferrantello is the surveyor courts, cities, and property owners call when the property line is the case.
“The profession itself is to define the property lines and measure the evidence we find.”
— Frank S. Ferrantello, PLS
Every land transaction and every dispute comes down to one question: where exactly does it begin and end? Frank answers that question under cross-examination, in front of zoning boards, on land where guesswork isn’t an option.
About Frank
Built the practice from the field up.
Frank didn’t inherit his reputation; he built it. He started in the field and drafting room of John P. Ferrantello, P.C. in 1998, earned his license in 2010, and founded Ferrantello Land Surveying, P.C. in 2011, growing it into a full-service survey and design authority trusted by attorneys, banks, developers, and municipalities across the five boroughs and Long Island.
Today, as President of the Ferrantello Group, he leads high-rise, air rights, and construction surveys that most firms never get close to, backed by a Civil Engineering and Land Use Planning background from Hofstra University.

The Expert Witness
Where evidence meets cross-examination.
Attorneys don't hire an expert witness to agree with them; they hire one who can survive cross-examination and still be right. Frank has provided sworn testimony and expert affidavits across nearly every jurisdiction in NYC and Long Island. If your case needs a survey that can hold up in a courtroom, not just at a closing table, this is the resume you want on file.

Property lines don't wait for convenient timing.
Boundary disputes escalate. Zoning deadlines pass. Closings fall through over one unresolved survey. Every week without a current survey is a week someone else could challenge your line first.
