So I think I figured out how to work around the header issue. Our "practice name" will be the first line of our address. Then in the first line of the address fields will be our Suite #, and then the city, state, and zip. That way there is no name on any header that could be construed as a partnership or corporation.
So our header will look like:
123 Main Street
Suite #789
Anywhere, WA 98000
Phone 360-123-4567 Fax 360-789-1234
