Hello, I’m Matthew Rosario, a New York mobile notary public with MJR Studio. I offer professional notary services on Long Island, serving the area between Southampton and Montauk. My focus is on making the notarization process clear, convenient, and respectful of your time.

I provide mobile notary and in-person notarization services for clients who need a notary to meet them where service is needed within my Long Island coverage area. Whether you are coordinating an appointment in Southampton, Montauk, or nearby communities between the two, I aim to provide dependable support with a friendly and professional approach.

I understand that notarizations often involve important documents, so I take care to handle each appointment with attention, courtesy, and confidentiality.
