We have been going to Dr. Gad Kletter at Children’s Hospital in Seattle since our daughter was born.  He is very thorough and we really like him.  Extremely intelligent. 

He said he is not recommending the circadian dosing only because of his concern that it might be difficult for parents to sustain.  I get the feeling he deals with some parents who do not understand the importance of good dosing, blood draws, etc.  Other than that concern, he said the results and feedback have been good.  He also always seems to have the latest info and studies. 

We have not heard of Dr. Gunther, but that is only due to the fact that we are happy with Dr. Kletter.  Let me know how things go - email me anytime at CDOW466@aol.com.
