Can I sue a physician personally for making false accusations about me at work?

I am a nurse working for a medical group that has several physicians in various locations. In my office there are 4 surgeons and 2 nurses. I assist 2 of the surgeons and the other nurse assists the other 2. I also assisted 3 other physicians at other locations, they would request me when they needed me. All 3 of these physicians made several requests to HR that I be transferred to work for them due to my skills and abilities. I was never written up, never reprimanded for anything. One of the surgeons in my office that I am not assigned to/ hired for to assist sent an email to my manager requesting I be terminated due to poor performance. He cited several examples all of which are false. None can be verified because they never occurred. There is nothing in my employee file. His accusations are totally unfounded. I was terminated 3 days later citing poor performance. He didn't like me and has now ruined my career. Thank you
