My oldest sister is POA and has taken over the schedule for companions for my Mom. Now that we are moving to the stage where these companions need to be health care providers, she will not release the reins and is superceding my role as health care representative. She says she is too busy to update the family. I have time and am very good at communicating updates. I want to bring in a geriatric manager and arrange respite for my brother who lives with my mother. My sister, who has a very strained relationship with my brother is not allowing me to help resolve these issues.
