Testimonials
Frank Devine, Founder;Accelerated Improvement:
"I have trained more than 900 facilitators in my 'leadership as a system' approach to systematic excellence and Siobhan is an outstanding example to all the others! She does not merely deliver the material but she enhances and adapts it to different individual and team needs.
In a tough global market, leadership needs to create competitive advantage in ways that are difficult for competitors to copy; Siobhan understands how to deliver this. She doesn't just deliver leadership development proven across multiple sectors and in every continent, she understands the science and philosophy that underlies it.
As a powerful example, at Boston Scientific, she led a highly talented team that sustained and enhanced the remarkable gains made in the largest (3,200 employee) Rapid Mass Engagement culture change ever implemented."

Gretta Collins, Director of Process Development, ex-Boston Scientific:
"I have had the privilege of working with Siobhán for more than 15 years, and throughout that time she has consistently demonstrated exceptional professionalism and unwavering dedication. Her leadership skills are second to none—she leads with clarity, integrity, and a genuine commitment to bringing out the best in others.
What truly sets her apart is her deep expertise in change management, cultural transformation, and employee engagement. She not only understands these areas at a strategic level, but she also has the rare ability to translate complex concepts into practical, effective actions that drive lasting impact. Whether guiding teams through significant organisational shifts or helping shape a positive, thriving culture, she approaches every challenge with insight, composure, and a solutions-focused mindset.
Working alongside her was an honour. Any organisation would be fortunate to have her guiding its most important initiatives."

John Reidy, former Production Manager, Boston Scientific:
"I worked with Siobhan collaboratively for about 15 years, covering everything from the day-to-day HR and ER issues right up to developing and supporting the leadership programme, as well as co-facilitating and leading various projects.
What always struck me was her straight-talking, knowledgeable, and no-nonsense approach to work. She simply got things done. Our conversations always created opportunities to learn, and she takes the time needed to truly understand what's happening on the ground before she moves. She has a real skill for getting different people and teams to work together effectively"

Amit S, Senior Engineering Manager, Medical Device Manufacturing:
"After years of standard leadership courses, Siobhán's program was a breath of fresh air and a genuine turning point for me. Her straight-talking approach, paired with her experience, cuts right to the heart of what matters. The collaborative environment she created, where we shared our own experiences, cemented the learning. It's a testament to the program's quality that I still actively practice these foundational skills years later."
