I am very familiar with that area. You shouldn't have any problems with safety. As far as home care agencies, check into St. Joseph Mercy Home Care in Ypsilanti. I worked for their sister company in Pontiac and it was a good experience. Also, check University of Michigan Home Care. I bet you will see some interesting cases although I haven't had any personal experience with them. Lastly, try Heartland in Ann Arbor. NOT the Southfield branch. I trained at the Ann Arbor branch for a week and the people were great. Good Luck!
