This sounds an awful lot like a classwork assignment, for which we can't provide straight forward responses. Also, the limited fonts for this sight would make diagramming a near impossibility. I will give you a couple of hints as to how you may get started. You need to determine the relationships and their type between the various entities and provide for keys to indicate those relationships. As examples, a care center will have a number of physicians so there's a one to many relationship, physicians can provide different treatments and treatments migth be provided by many physicians so there's a many to many relationship there, and I assume that a physician is also an employee so there would be a one to one relationship there. Once that analysis is completed, you can then add the foreign keys to establish the relationships such as adding an employee_id to the physicians table as a foreign key to the employees table. Good luck.
