pancreatic cancer specialist on Long Island ?

Hi,
If anyone can help me, I am desperately trying to find an experienced pancreatic cancer specialist/surgeon for my dad. He has symptoms and cat scan does not look good at all. I want to bring him to the best doctor there is to do his consultation and make the correct diagnosis and do his biopsy. We live on Long Island, New York. Someone wrote in about a Dr Kim in Garden City Long Island but I can't seem to locate him/her.
Please, if anyone knows who I can bring him to, write back to me. My heart feels like it is being wripped out of my chest and I can't breathe right. Thank you so very much for caring to write to me.
Joanne
