Employee News

We would like to extend our congratulations to Alicia Portalska, who will be our new Vice President of Marketing from January 1. This follows last week's news of Vice President Louis Larson's retirement at the end of the year. Ms. Portalska joined us as a trainee marketing assistant four years ago and was recently promoted to marketing director. We would like to thank Ms. Portalska for her dedication and outstanding contribution to the marketing department. Her work has had a significant impact on our sales figures. It is in part thanks to her tireless efforts that we have exceeded our sales targets this year. Congratulations, Ms. Portalska! Your example is an inspiration to us all.
