Others who list this employer on the register
The register gives this attorney’s employer as “Cohen, Seglias, Pallas, Greenhall & Furman, P.C.”. We count that spelling with Cohen Seglias Pallas Greenhall & Furman PC, the name most registrants give for the firm now; the register does not say where the attorney works today.

How to confirm it officially
For a statement of John Alan Greenhall’s standing, contact the Attorney Registration Unit of the NY Office of Court Administration (nycourts.gov/attorneys), or ask the Appellate Division, Third Department, which admitted John Alan Greenhall in 2013. The register places the office outside New York, so a complaint would go to that department’s grievance committee (22 NYCRR 1240.7(a)(2)).
This page reads the register file of Sep 29, 2026, and the court system’s own search can be newer; the register shows only the current value, so a suspension that ended before the files we hold, or a censure, leaves no trace here (Appellate Division decisions are published through the court system’s Law Reporting Bureau).
