I've had a great relationship and experience with our pedi, Dr. Lisa Winters Smith. She's associated with The University of Chicago Hospitals and practices out of the office at 87th and Greenwood. Dd will be 3 next month and has had 1 vaccination - 1 she got before we realized what we were doing!
And when it was time for her to start her early childhood program, Dr. Lisa (as we call her in my house), pulled out the appropriate form we needed for school (Waldorf, so, they weren't really asking) regarding DD's health/vaccinations (or lack thereof).
She's been great!
