In+Addition has announced that it has been appointed to handle the PR for JOY Bomb London. The brand creates multi-sensory installations in an aim to create fun and memorable moments. JOY Bomb London was created by Amy Broch after her husband Sean's 2018 ALS diagnosis. Immediately, the couple began exploring every treatment available in order to treat and slow the progression of the disease. Learning that happiness was linked to better treatment outcomes and longevity for ALS patients was a big moment. Proceeds from every installation support the Healey Center for ALS in memory of Sean who passed in May of 2020. It is the largest hospital-based research program in the world and supports early-stage trials of promising ALS treatments.
