Private elementary schools refusing admission?

My daughter was diagnosed 8 months ago with epilepsy and we are now looking for an elementary school for her (in NYC). She is on medication and is having seizures rather rarely (every few weeks). The two local private schools to which we applied both refused her admission - one with the spurious claim that they were 'full', and the other by explicitly saying they were unable to manage her epilepsy. I understand that this is illegal, but am unsure what to do now. Understandably, we don't want to send our child to a school that has both discriminated against and rejected her, but feel we cannot let this injustice stand - not least to prevent it happening to the next kid. We feel we don't want to invest money and effort into a legal case, but would like to make the schools aware that this behavior is both unlawful and unfair. Does anyone have any suggestions as to what action we could take? Thanks for your help, Simon.
