Akira andMatsumoto(Mikey)
Facilitator

With nearly 18 years in the retail industry, I held roles such as sales, store manager, trainer, and area manager. These experiences taught me that when people grow, organizations grow. Supporting others made me reflect on my own growth and whether I still had something to offer. To challenge myself, I moved into a new industry. Now, I work to create training experiences that resonate emotionally and leave a lasting impression—while continuing to grow with my clients.

As a consultant, organisational psychologist, account manager and researcher…I endeavour to encompass all the different aspects of life in the organisation! To me the organization is a magic happening between individuals, groups and their work contexts. I deal with the entire consulting process: from the proposal development, to the client management, intervention delivery and evaluation process. I love the countryside, baking cakes & capoeira!
