Usefulness of Grant Writing to APMC?

[Karl Ben]

Members,

Good afternoon.  My wife is a local pediatrician with a large volume medical
practice, located in a small (pop. less than 5,000) southern city.  She
expressed an interest in grant writing--and specifically enrolling me in the
local university's business division grant writing offerings--but I am at a
loss as to what, or rather how APMC (A Professional Medical Corporation)
might benefit from grant writing.  I have always associated grant writing
with nonprofits.  Of course, this community of technical writers would know.
Looking forward to your responses.

Thanks, Karl
