CPLR 308(2) permits personal service on a natural person “by delivering the summons within the state to a person of suitable age and discretion at the actual place of business” of the person to be served and, within 20 days thereafter, mailing a copy of the [*2]summons to the actual place of business in a specified manner (CPLR 308[2]). CPLR 308(2) requires strict compliance and the plaintiff has the burden of proving, by a preponderance of the credible evidence, that service was properly made (see Kearney v Neurosurgeons of N.Y., 31 AD3d 390, 391; McCray v Petrini, 212 AD2d 676).
