It is with extreme sadness that we have bad news to tell. Dr. Crook recently died from a massive stroke in Jackson, TN, and his family has donated his body to science. He will be greatly missed by parents of PAC. Many of our children would not be taking such great strides, making progress, or enjoying life as much as they are, if it was not for the wonderful work of Dr. Crook. Thank you Dr. Crook for putting our children's health first, educating the medical profession, and arming us with the necessary information to be strong advocates for our children against many odds and obstacles. We hope that another brave soul will take up the challenge to continue this work with as much dignity, understanding, care and forcefulness as that of Dr. Crook.
