I majored in MIS in college and was able to get a web developer job arranged before graduation. A few years after that I got a different web dev job, and I've been here for more than 10 years. During that time I've been interviewed for about a dozen job opportunities and received offers for about half of them. The field I'm in doesn't require a lot of person-to-person communication, and frankly the interviewers are probably used to interviewing a lot of socially-awkward candidates. I think that as long as you're up-front about your stutter, show a decent personality, and have some desired skills, you can do well in an interview. Of course, the IT field is much different than physical therapy, so I don't have a clue what it takes to get a foot in the door there. I think it comes down to employers looking for experience, but you can't get experience until someone takes a chance on hiring you. If your job market has too many candidates and not enough opportunities than the companies can afford to be very selective about whom they hire and opt for someone with work experience.
