Dr Ponder is a ped endo that also has type 1 for over 40 years and wears a pump and cgms and he has ran the TX Lions camp for over 20 years. I think he is a awsome Dr and he twitts from camp and is now going to twitt from his practice in corpus Tx. He told us at a dinner with him when we picked our daughter up that it is very important for our kids to be tested for vitamin D. he also has twittered about it. He says that 70% of the population is defecient in it. I am but did not realize what all vitamin D has been linked too! I will be getting my DD tested! I wanted to leave his twittter page so if you wanted to follow it you could. www.twitter.com/dr_steve_ponder Thanks for reading and I hope this info is helpful!
