Mom's doctor of 30 years retired and he had just joined an HMO, so we are left with a new first time doctor in and HMO that we do not belong to. I am not sure what type of doctor to look for but I would like someone who understands her dementia. We have tried asking friends to no avail. She has Medicare and a Private 2ndary carrier so I know the insurance aspect but how do i find the RIGHT DOCTOR???
