A list of veterinarians in the area, along with the vets' contact info, is accessible at the Resources > Vets page. This list is organized according to the cities in which the vets are located, so that you can get a sense of which vets would be nearby depending on where a client lives. You may want to print this list as a reference. To do so, use the Print button from the Tools drop down menu at the top of the page.
When in a Client Profile you will be able to see which vet the client uses in the Veterinarian section of the profile at the bottom. Pet Profiles may have specific vets different than what is set in the Client Profile.
