About us

Safety is our mission

Our story

We are a global industry leader, partnering with global organisations to achieve breakthrough results in safety, mental health and leadership.

At the Jonah Group, we work with you at a personal level to understand the DNA of your organisation. We deliver sustainable results by providing solutions that will become deeply embedded and thrive throughout your organisation. Our intent is authentic and our story personal. It stems from our founders’ personal experiences.

Director Nada Wentzel was working in the crisis management team at Esso Australia when the Longford incident occurred in 1998. Two people died and seven were severely burnt. She knew the people affected and saw the effects on the people around them both at work and at home.

Less than six months later, both Nada and Robert were themselves involved in a horrific personal accident. Nada suffered burns to 35% of her body, requiring several skin graft operations and months of rehab. It took her months to learn to walk again and 10 years to have the confidence to wear skirts without opaque stockings.

Nada says, “Rob and I were both mechanical engineers at the time working in high hazard industries. The incident involved camping; it wasn’t work-related. Logically, I can see how it could have been prevented, but when you’re exhausted, cold, hungry and distracted, nothing is logical. People have incidents because their brains are not always in logical mode. Safety is not rational. It is a complex weave of logic and emotion”

Our values

Love what we do

We’re passionate and committed to making a difference and connecting people to the very essence of what it means to be human. We love what we do. We pour our hearts into helping people realise that the choices and decisions they make can save lives.

Authentic partnership

Gone are the days when a single person holds all the answers. Collaboration and collective mastery are a key part of how we work with each other and our clients. It’s why we’re known for generating results that thrive well after we’ve left the room.

Take ownership

We’re up to big things. Causing behavioural and mindset shifts requires muscle and resilience. It involves having the hard conversations, owning the results and delivering on our promises. It’s not always easy, but it is what our reputation is built on.

Respect your business

We value honesty, transparency and are super conscious of making sure you get absolute value for money. Our people are awesome. Each and everyone one of us acts as the owner of our business. We are accountable for actions and take pride in building strong and honest relationships. Sounds awesome? It is.

I think it's fair to say that the feedback on the Leading Safety Program has been nothing short of excellent. It certainly exceeded my expectations in terms of the feedback that we're getting and I really think it's created a momentum in the organisation. I see this evidence in many, many ways recently. From my perspective, The Jonah Group bring real world experience, real examples, and hold participants of the program accountable for their responsibilities to take that content that they're getting from the program applied to themselves and assist them in their safety journey.
