Does anyone have experience with corporate guardianship?

Hi,  I consulted with my attorney last week regarding my ability to be my oldest brother's Legal Guardian...I have so many of my own life challenges, and began to realize I wouldn't be able to really provide my brother with the level of assistance he needs.

The attorney then suggested shifting to Corp. Guardian, and I basically have an ok feeling about deciding that. I understand that health care decisions, and other major areas of his life, will be decided upon by the Corp. Guardian. It was /is my belief that the professionals would know best.

However I'm aware that there are 'better' corp guards and maybe 'not as good'. Would appreciate any feedback or ideas. Thanks alot.
