Five years ago, Megan Thomas was a busy executive seeking to keep her and her employees current with new technology. She realized that many small companies were facing the same dilemma. Using her life savings and money from investors, Megan founded Corporate Technology Center. Corporate Technology Center’s primary objective is to offer technology update seminars to local business executives and their employees. A wide variety of seminars is offered, including ones covering operating systems, spreadsheets, word processing, database management, Internet, Web page design, and telecommunications.

Although Corporate Technology Center offers seminars at its own campus, it also provides on-site training for local companies. One-day, two-day, or four-day seminars are offered. Courses are open to a minimum of twenty students and a maximum of forty students. Although several staff members are capable of teaching any given course, generally only one staff member teaches a given course on a given date.
