Hello,
I have a 4 month old son and we use Wantagh Peds. They are wonderful. There are four doctors, he's seen them all and we are comfortable with all of them. We originally were going to uses Bellmore Peds because they were affiliated with where we were delivering (South Nassau hosp.). Turns out that didn't matter (Wantagh Peds was our second choice but I was so worried about the peds. being associated w/our delivering hospital that we picked Bellmore.) Four days after our son Gabriel was born, he was admitted into the Winthrop ER and then ICU. He had an emergency operation and was transferred to Columbia Presbyterian in the city. When he was discharged two weeks later, we switched him to Wantagh Peds. because upon our Gabriel's emergency, we were hugely disappointed with Bellmore Pediatrics and their response (and I should say Winthrop hosp.) When we switched to Wantagh, they learned about Gabriel's case from Columbia, got all his records and every doctor there knew about him. Plus when we see them now, they all know his story. When they check him out, I don't feel like I constantly have to say "This is THAT baby." I would recommend them highly. Good luck!
P.S. I should mention that I do know people that are happy with Bellmore Peds but we had a not so great experience.
