Yes, I have heard of the CAH Association. Yes, you are right regarding the area code (its in Northern MN). I contacted them some years ago. I think they thought there address and numbers were no longer on the internet or where ever the information was received. It is not a physician organization or necessarily an association. I think it was one of the first "Moms" who became very interested in getting out the information regarding the importance of CAH. I believe they prefer not to be contacted.
