After posting a photo of the offending sign, the image has received hundreds of comments.
"I don't see why there are so many comments on how this is so unprofessional on the staff's part," one user wrote. "What about the doctor who refuses to work with another care giver because of her gender?
"Why would the wife be jealous of the nurse but not the other females in the office," another noted.
Another said: "If he quit his practice because they hired a woman, then he is unprofessional."
Many thought the staff who posted the note were the ones in the wrong for revealing private details.
"The doctors office acted unprofessional and inappropriate by putting up information on the reception window," an angered user wrote.
Someone else said: "Regardless of the reason he left, this sign should not have been posted."
Others branded the whole scenario absurd: "You gotta be kidding, right? This sounds so ridiculous."
"The lack of confidentiality is appalling. I would be concerned about this if I were a patient," another said.
The female nurse practitioner told Fox 2 on her first day of the job the doctor who resigned refused to speak with her.
However, the doctor has yet to comment on the alleged incident and his departure from the medical centre.
