What is a good medical billing, health care, office assistance, medical business management company name?

Something with Medical Management in the name would be good. Perhaps her last name, or something she likes in front of it - like Somers Medical Management (or if she liked lighthouses, for example, Lighthouse Medical Management).

Could also be something as simple as Comprehensive Medical Management.

I'd either go simple with "Somers Medical Management Corp" (if your moms last name is the same as yours obviously). Or think of something that starts with an "A" like AAA Medical Mgmt, so that it's first in the phone book!
