DIRECTOR'S MESSAGE

Why I Joined My Father's Company

Honestly, First of all I would like to tell you all from my heart “The greatest gift I ever had come from God; I call him Dad! The small public relations firm he started 39 years before was now a growing company. I saw his Innovative ideas, Devotion, Dedication, Honesty, & more Attitudes. When I saw that qualities from him, I hoped to see them from myself also. Not only that but also I wanted to be an Entrepreneur like him. That’s why I Joined My Father’s Company. Through following him I improved my Qualifications, Attitudes & Experience day by day. Finally, I expect to invent excellent products just like my father did. Also I would do a great service to my country as well as my business field by introducing these products to Local & Foreign market.

Thank you..!
Director – Shanaka Salwathura
