I work with a bunch of people with MD, PhD, etc. and I call them Dr. so and so, or Professor so and so. Even the ones who I knew as students. Maybe in a social situation I would call them Fred, Mary, Santhi, etc. But at work, it's a sign of respect. I don't call the folks I don't work with who have earned their MD, PhD, etc. Doctor - it's a different relationship.

SAVING ONE DOG may not change the world,
but it CHANGES THE WORLD for that one dog.
American Brittany Rescue always needs foster homes. Please think about helping that one dog.
