“There are very few consultants that I would recommend, but Sheila is one of them. Sheila worked with my leadership team in establishing our Customer centered conversations framework, within our Billing and Receivables team. Sheila demonstrated a passion for people like I have never witnessed before. Her passion was contagious, with my team transforming from a transactional business unit to a true customer centric service provider with her support and expertise.


Sheila’s understanding of people, behaviours and mindsets was exceptional. I personally learned so much from her sessions and coaching, skills that I will take with me throughout my career. I would highly recommend Sheila to anyone seeking to dramatically change the culture of a working environment; to improve team health and wellbeing; and to support leaders in building skills to lead teams to high performance.

"Thanks Mimma –  I must say the level of support you gave me, particularly during the first 12 months was outstanding – your high level of capability to support the entire team in your Project Management role which was underpinned by a very high breadth and depth of end to end consultancy has been quite outstanding – in discussions I have had with various team members over the journey, they all speak so very highly of you not only in your professional role but also as a great person who they admire so much."
