My 12 year old son was recently diagnosed with ASD and I'm pretty sure he also has Tourettes. I am a newbie to this site and am looking for Houston-area providers who take a more holistic approach to these conditions. Posters on the PANDA thread speak highly of Dr. Doctor, but does he also work with ASD patients? Would also appreciate the names of nutritionists who can help with an elimination diet and vitamins. Thanks.
