When addressing a physician's assistant, it's important to understand their professional title. While physician's assistants play a crucial role in healthcare, they typically should not be addressed as "doctor." The title "doctor" is reserved for individuals who hold a doctoral degree, such as medical doctors (MDs) or doctors of osteopathic medicine (DOs). Physician's assistants usually hold a master's degree and work under the supervision of physicians, providing medical care and performing certain tasks delegated by doctors. Therefore, it's more appropriate to address them using their professional title of "physician's assistant" or "PA."
