'Making Work Enjoyable for Children' I’ve spent 17 years in retail, gaining experience in sales, customer service, training, HR, and recruitment. This taught me that business growth relies on people’s growth, inspiring me to pursue my own and motivate children. A key moment was a training program at Impact Co. 11 years ago, sparking my passion for talent and organizational development. As a working mom, I focus on balance—committing to work weekdays and spending time with my toddler daughter on weekends. This balance is key.
