I was inspired by experiential learning on a leadership programme in 1992 and have worked for Impact ever since. Experiential learning and reflection alongside theory and skills input is a platform for real behaviour change for leaders. My passion is building an organisation worth working for and supporting our clients by developing people. I play football and enjoy discussing the match with friends. Drinking beer maybe more important than playing football.

Shino andTakahashi(Shelly)
Assistant Manager, Human Development

'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.

I came to Impact as an Intern in 2023 and here I am again in 2025! That’s because Impact is a great place to learn and the people are even better.

I’m the liaison between our marketing and business development team and my job is to enhance our digital marketing and BD function. In my free time you can find me surfing out on the waves (usually wiping out), horseback riding, or behind a guitar and a microphone.

With over 20 years at Impact, I've contributed to the design and delivery of over a thousand programmes. And what if the secret of success is to continue to refine something even if you've done it dozens of times? Outside of work, I like gardening and interior design. I live on the crest of an extinct volcano, with the Mediterranean Sea to my west. After sunset I keep fit by jogging around a golf course.
