Question for Christian doctors (MD's) & dentists (DMD, DDS) ...?

Do any Christian doctors or dentists have a network where Christians can locate them and if they do are they willing to charge less money to others, especially Christians (Gal. 6:10) who are uninsured or indigent? Of course the medical "oath" requires this, but that seems more like a pipedream in today's society. Thank you for your answers in advance!
