Association of Innovation and Design
Since the re-establishment of this association in January 2021 after a period of inactivity, The Association of Innovation & Design of S.Thomas’ College Mount Lavinia has taken steps to ensure its activeness within the clubs and societies of college by recruiting individuals who show a keen interest in the fields of innovation and design. The Association takes pride in uplifting the innovative thinking and designing skills within fellow Thomians and wish to do so in the years to come.
