I have also known Dottie for many years...but haven't spoken in quite a long time. Last I saw her her son was about 6 months and I believe he would be about 4 or 5 now. Her personal website is not working right now...maybe she does not have it anymore. I will try it again later and see if it works.
She is an absolute inspiration and wonderful person! I remember when she got her tx, we have the same doctor and used to run a relay in the Boston marathon together, back when it was ok (I was around 10).
