Well, if money isn't an issue, there is always the Goddard school off Western and just south of 150th. it's REALLY expensive, but REALLY nice!!!

Unfortunately, I have had difficulty finding "quality" childcare around the area as well

There are some other good ones that I have heard of, but they are SOKC

OH, st. lukes downtown (or is that not north enough for you)

Good luck and it's so hard, but remember, you get what you pay for!!!
