Hello R.,
If you don't mind driving a little bit down Rte 83, you may want to consider the doctor that my children see, Gregory Ozark. He is both a Pediatrician and an Internal Medicine doc and we LOVE him. His office is at the intersection of 75th St & Lemont Rd, at the Loyola University Health System clinic in Darien.
Another doctor at that location that we love is Dr. Brent Rieger (also Peds and Int Med).
Dr. Ozark came very highly recommended to us by the Neonatologists who cared for our oldest son when he was born and hospitalized.
Hope this helps, and welcome to the area!
