To Whom It May Concern:

Joanne Twining Williams has worked as a microcomputer applications training consultant for me, and the 687 employees of Johnson & Johnson Medical Inc., Sherman, Texas, through the Corporate Services Department of Grayson County College, regularly since October 1994.

Joanne has provided training in a variety of applications for all levels of employee, from first shift "power user" executives to third shift production workers who are new to computers. Her trainee evaluations are consistently excellent, and she is almost always rated as the most significant factor in the success of her seminars. She has demonstrated an outstanding ability to interpret computers to our employees and to quickly bring them to confidence and competence. Her unique communication style and ability to effectively manage and satisfy diverse learning styles in a group environment, in addition to her professional commitment to a job well done, and her flexibility, creativity, innovation and enthusiasm have made her a vital member of our Information System team.

Please feel free to contact me should you have any questions or require further information.

Most sincerely,
