Testimonials

Ota Savaiinaea Aben

Ota Savaiinaea Aben

"The team at Mantle have been pivotal in helping my leadership team shift to a more empowered, inclusive, and performance driven culture. Their focus on not only the skills and tools to do that, but most importantly the mindset underpinning it, has enabled us to heighten engagement, accountability, and growth within all team members, both our leaders and team members.

Mantle brought a dedicated focus to truly understanding our needs through a consultative process that continued throughout our engagement with them.

As a result, the development and coaching given was focused, tailored specifically to our needs, and provided strong links to the wider MBIE organisation. I highly recommend them to any organisation that is seeking real behaviour change and growth in their leaders and overall performance."

“I’ve witnessed well-meaning performance “feedback” having the unintended consequence of actually detracting from a team’s ability to reach its potential… I now have a better understanding of how to keep a team focussed on improving rather than just proving when reviewing performance.”

“You quickly get under the skin of the organisation and you offer leading edge thinking on development and applying neuroscience. Your services are practical and pragmatic not academic or heavy on theory. We now have more confident and engaged leaders and we are growing our leadership mind-set and opportunities. You were quickly able to add value up front and I like your flexibility and collegial approach.”
