There are many factors which contribute to the need for a DMM. DMMs work with senior citizens, people whose careers make it difficult for them to find time for their own paperwork, and with people whose medical issues simply make it difficult to keep up with their finances, among others.
Within the senior client base, most have a need for DMM services due to a physical change precipitated by the aging process, such as limited vision, arthritis or other conditions which limit the ability to write, dementia, or a simple loss of ability to follow through on tasks. Some others are so active in their retirement that travel and social activities make it difficult to keep up with paperwork, and they prefer to simply let someone else handle things for them.
It is not uncommon for the adult child of an older person to seek the assistance of a DMM if the child does not feel they have the time or ability to maintain their parents’ affairs.
