My son, 8 years old, has a diagnosis of PDD, a mild form of Autism. A friend suggested that I take him to Dr. Callahan to make sure he wasn’t suffering from pinched nerves. He fought the treatment at first, but now talks about needing an adjustment! I think he intuitively knows that this is good for him. After an adjustment, he is more focused, and less stressed. It makes a difference in everything he has to do at 8 years old! Dr. Callahan, thank you for improving the health and wellness of my entire family.
