Your healthcare directive will be your voice when you need it most.
Ensure you receive all of the care and only the care you desire.
Support your healthcare agents by offering clear goals and guidelines for your care, as well as statements of values and beliefs.
Give you and those you love peace of mind in knowing your wishes are understood and can be followed.
Help your loved ones stay united, loving and supporting you and one another instead of arguing over your care.
Keep your healthcare decisions private, within the family, instead of debated by a hospital ethics committee, or worse yet, splashed in the media.
