Client testimonials

Good Grief

Good Grief engaged Atomic Tangerine to renew and re-design our website. We were looking to improve user experience, communication and messaging, and create a more appropriate look and feel. Atomic Tangerine immersed themselves not only in the Good Grief website, but also the Good Grief business model – but even further into the fabric of why and how we did what we do, helping people deal with their grief. Atomic Tangerine had the capacity to listen and absorb exactly what we wanted to achieve. They brought their analytic skills to bear to take the website apart and then re-design it so that every user experience would be improved. They were also able to provide a set of variables that would enable the programmers to make the website consistent. Good Grief’s website required on the one hand hard-edged business operations, but also on the other, emotional sensitivity. All was delivered on time and in an engaging and cheerful manner.

Sybil is collaborative, innovative and a real pleasure to work with. I have known Sybil for over three years and in that time worked with her on a broad range of projects for which she has managed everything from marketing and bid preparation projects to business process optimisation.

Sybil is a key adviser to my business. Sybil is able to seamlessly move from detail to big picture without losing the thread of what’s important. She is a creative powerhouse – continuously generating new ideas and challenging group-think. Most importantly she is a delight to work with.

Toby Ralph

Sybil is utterly fabulous; driven, detailed and savvy. But the world isn't running out of people with these attributes. A guy called Bill Bernbach said "Life is too short to work with people you don't like." (Actually I think his language was a little more robust, but let's stay nice.) That's what really distinguishes Sybil: she is an utter delight and makes tasks fun. People love to work with her and that gets things done. If you are considering hiring her and for some reason don't; you're wrong.

We have recently engaged with Sybil as our chief consultant on the refresh of our current website. We have found her to be a breeze to work with; quickly understanding our ideas and concepts. She has offered us intelligent insight on our current website, where she sees our industry heading, and how to put together a creative brief. She has been extremely flexible when it comes to fitting in with our tight schedule, and we are on track to finalise the project in good time. We have been very impressed with her work and fully intend to work with her in the future.

Michael Partis

Wizard Home Loans

I have always been impressed with how quickly Sybil is able to understand a business and identify strategic changes required to implement a plan. I have no hesitation in recommending Sybil's work and would enjoy working with her again in the future.

Paul Sinclair
Business Initiatives Manager


Sybil worked with us in the development of processes and structure to productise a number of our managed service offerings. This process turned out to be a much larger project than originally thought and Sybil's hard work and methodologies were instrumental in that development. I would be happy to recommend her to projects in this type.

Craig Sommerville
Managing Director


Sybil is intelligent, professional and her experience shines through in the quality of outcomes. She brings a fabulous concoction of pragmatism, value and 'cut through' in getting to the point using logic, data and emotional intelligence.
