I define ethical as following the accepted principles of right and wrong that govern the conduct of a profession. I consider it unethical for a doctor to accept bribes from phamaceutical representatives. I don't think that is what you want.
I think what you want is a doctor that will understand and respect your moral standards about what is and is not appropriate to respect your beliefs. The best thing would likely be to simply look in the phone book and find all the endos listed. From there, you can look into the background of your endo (see my discussion on how to do this). In the end, you can ask the doctors front staff about them and how they might treat you and you can just walk out from an appointment if you don't like them. From what you have written, you would probably be most comfortable with a female doctor.
You may not get a response asking for an "ethical" doctor/clinic. You might consider rephrasing your request to finding a doctor who understands and respects your moral choices.
