My father, a survivor of oral cancer, is having trouble finding a nutrionist who specializes in nutrition plans for individuals who have had oral cancer. He has trouble manipulating food due to the loss of part of his tongue. He has been drinking an ensure-like shake for the past two yrs. but has had trouble keeping weight on. Unfortunately the nutrionist he saw wasn't used to dealing with his situation and couldn't assist him in creating a nutrition plan, aside from telling him to continue his current plan. We're located in State College,PA. Are there any doctors others can recommend? or any other advice anyone could provide would be extremely helpful and greatly appreciated! Thanks!
