DECISION ORDER
ORDERED that the judgment is affirmed, with one bill of costs to the respondents appearing separately and filing separate briefs.
The plaintiff did not serve a notice pursuant to CPLR 3101(d) and acknowledged he was not going to present expert opinion testimony to prove that the defendants' conduct constituted a deviation from the requisite standard of care. Accordingly, he was necessarily unable to make out a prima facie case, and the complaint was properly dismissed (see, Kalkan v. Nyack Hosp., 214 A.D.2d 538 ).
