I worked with another Denise. She was a Recreation Therapist, I was an Occupational Therapist so we were Denise RT and Denise OT. When I talk to her, even now, and she answers the phone, I say "Hi Denise, it's the Other Denise!" We both quit those jobs on the same day because we'd both gotten jobs at another hospital on the same unit again. It was great

She got married before me or else we would have had the same initials for a while too.
I've never met a man named Denise.. I doubt there are any. Dennis maybe...
