I live in Oak Lawn, but travel to Oak Park/River Forest for our family doc. She sees all of us and has a very laid back approach - which I love. She is a HUGE supporter of breastfeeding. Dr. Susan Locke on Lake St. in River Forest. Since my husband and I both work full time and live so far away she is always willing to answer questions over the phone (though often through her nurses) and will do her best to avoid us having to come in with a sick kid. She either gives suggestions over the phone or just calls in a prescription if necessary. She's done this for my husband and I as well.
We looked at HomeFirst. They were a little TOO relaxed/laid back for us and the doc I met with spent a lot of our interview time making me feel guilty for going back to work and tried to get me to join some work at home pyramid scheme. Just turned me off completely.
Good luck in your search for the right doc!
