Congrats! Dr. Kofinas is amazing.. if you have out-of-network benefits (he doesn't take in-network) then definitely go to him- he's the BEST perinatologist on LI.
I want to say I was released to him around 8 weeks? You will also need a regular OB as he doesn't deliver.
Most people go with the tried-and-true Pilliteri/Kofinas combo (I did, were both great).
