So don't expect a laundry list of all your faults from me. Expect me to be focused, supportive, but persistent. Communication skills are needed by everyone who needs to deal with other people. My clients may be people looking for promotion, facing new work demands for presentations, job seekers, people who are facing their oral exams for a professional license, attorneys, professionals having to present papers, young adults interviewing for their first job. Yes, sometimes people can use a little grooming as they function at new levels of their work.
Communicative behavior is formed in the early years of development.
In this case, the referring individual sees potential waiting to be developed. This requires all the skill a speech coach can muster, but the coach can act as the intervening element to solve interpersonal communication problems so that both parties are satisfied with the outcome. Probably not, unless you have a medical condition causing your communication problem, like a stroke or cancer of the mouth. Typically, my clients do not have medical conditions, they simply want to get good. However, if your work on communication skills is work related, it will be tax deductible.
