Description Using the telephone is easy -- place earpiece to ear and speak; mastering the telephone, however, is a different animal. Telemasters is a sales training firm that specializes in teaching telephone skills to sales and customer service employees. The company assesses needs, analyzes calls, and creates programs to make the time spent on the phone more effective. It assists with such issues as developing good time management skills, building long-term client relationships, acknowledging strong sales opportunities, and leaving effective voice mails. President Steve Kloysa founded Telemasters in 1990 after he spent years studying successful sales call strategies.
