One of my best friends has a P.H. D. in Psychology. I was there for all of her hard work in the doctoral program, and I am extremely proud of all of her accomplishments and the work she is doing now. Is it correct to list her as Dr. xyz in the wedding program and website? I feel like it is, but I am not sure I have ever seen it done like that. Does anyone know the proper etiquette for this? It should be pretty straight forward.
