The greatest reward is when an UnlimitU client shares how our partnership has helped them or their organisations achieve greater success and fulfilment.

UnlimitU delivered a 4 month High Performance & Wellbeing Program for Yamaha. It is evident from the moment you engage with Poppy that she is at the forefront of thinking in leadership, mental health and empowering teams. Poppy’s warm and genuine style enables her to instantly connect with people. Everyone who participated in our program cannot speak highly enough of Poppy’s immediate impact. Yamaha looks forward to ongoing collaborations with UnlimitU

Poppy more than delivered for Westpac’s Corporate Partner Program. She took the time to understand who we are as a business and what we are trying to achieve for our customers. Poppy delivered an amazing workshop that was well received by our corporate clients. I wholeheartedly recommend UnlimitU & will be working with Poppy on other initiatives.

After 4 weeks of private coaching with Poppy, I feel I have made significant progress, clarity, insight, and direction both personally and professionally. I have a clear roadmap, I feel a real sense of lightness, and excitement. Honestly, I feel genuinely happier in all aspects of my life after my time with Poppy.

Poppy is an inspirational, intelligent and passionate speaker and educator. 

Having worked closely with Poppy on the topics of working parents and women in leadership, Poppy is in her element giving people practical, high performance strategies for busy working professionals. I would highly recommend Poppy to organisations looking to achieve the performance edge.

TIXSTAR organise and plan a variety of events and experiences, we engaged Poppy for our International Women’s Day Breakfast at the MCG. Poppy was nothing short of outstanding and the level of engagement with the audience was fantastic. As a business we will definitely look to work with Poppy on-going and are excited for a great partnership.

Looking for a speaker who talks directly to your audience, leaving everyone inspired to be the best version of themselves?  Then Poppy is your speaker! Poppy is powerful, authentic and relatable. Our room of 100 woman were blown away by her powerful messages and delivery on Courageous Leadership. We will struggle to find another speaker that connected so well with our audience.

We were fortunate to have Poppy speak at our Ladies of Property International Women’s Day Luncheon where she gave an inspiring presentation on ‘How to be a Courageous Leader.’ Everyone was engaged from the minute she spoke. We received overwhelmingly positive feedback from many of our guests. Thank you Poppy for helping us deliver a brilliant event!

Poppy was an outstanding presenter at our Wellbeing Performance Breakfast at the Mornington Racing Club! Her lived experience combined with the science behind wellbeing really hit home with our guests, she talks the talk and walks the walk plus leads from the front in terms of promoting wellbeing in our community. We look forward to a great partnership ahead with Poppy!

Poppy is an open, warm and experienced professional who has the ability to captivate her audience with her engaging style, evidence based research, and ideas for practical implementation. Woking with Poppy to meet our brief was a seamless process and we look forward to working with UnlimitU ongoing

The combination of deep experience in coaching and training, her expertise in marketing and business, plus her ability to connect with people across all ages, levels and industries is part of what makes Poppy such a leader in her field.
