TTC & looking for an amazing OB/GYN

Hello All! I’m 36 and a mom of two (14 & 8). We are TTC #3. I’m only on cycle 1 and 6 DPO. I’m looking for an amazing OB/GYN that will deliver baby and see me throughout a pregnancy. My OB now is great but if she’s not on call another doctor from the practice can deliver and I’m not crazy about that. Preferably in Prospect Heights/Park Slope (or Manhattan below 23rd street) affiliated with Methodist in Brooklyn or Mt. Sinai in Manhattan (59th Street). Thanks in Advance!
