I just realized another example of a physician who decided to go after medical representative sales jobs. This one is actually a vet who specializes in domestic farm animals such as pigs and cattle. But after she soon realized that it was very involved to set up a rural clinic for this type of specialty, she pursued other career options but still staying within her vet medical field. This prompted her to become a medical sales representative. Since her communications skills were quite good, she was able to get a job with the vet products division of Pfizer which promotes to vets who specialize in farm animals.
Of course, she had to position herself as someone who was capable of doing a medical sales job. For more information on how you can also get a similar career, see Medical Representative Sales Jobs.
