I provided a wide-range of consulting, facilitating and training services to the Australian nonprofit sector over a 10-year period from 2009 through to 2019. During that period I was also in the process of completing my PhD research into change management in the nonprofit sector and have now expanded this research through my academic post at Excelsia College where I have recently been appointed to the position of Honorary Research Fellow. In this capacity I also continue my academic research into change management in the nonprofit sector, specifically dealing with implementation challenges associated with the National Disability Insurance Scheme by disability service providers.

These engagements with a large number of nonprofit organisations are evidenced in the numerous recommendations which have been reproduced below.

My consulting experience, couple with my historic and ongoing research has enabled me to continue to provide my successful Change Management Masterclass sessions which were first launched in 2018. For further information including Program dates and registration details, please contact me through the Contact page above.

Deirdre Cheers, CEO at Barnardos Australia

I have engaged David Rosenbaum on two discrete occasions for work in the area of risk management frameworks suitable for (and tailored to) the not for profit environment. He has delivered in a timely manner and is expert in this area. I have no hesitation in recommending him.

Donna Bain, General Manager, Self Help Workplace

David has worked with the Self Help Workplace Board and senior staff to assist the organ isatin understand and respond to the challenges and opportunities created by the introduction of the National Disability Insurance Scheme and other issues affecting the social enterprise. David demonstrated a strategic understanding of the sector and our business and supported the organisation to identify and analyse the issues and develop realistic action plans that the organisation has pursued. The organisation values David’s insights and approach and would be very happy to work with him again.

Gavin Nicholson, National Unit Convenor – Australian Institute of Management Business School

Dr. David Rosenbaum is a person who possesses significant business knowledge across the finance, change management and not for profit sectors. He has regularly presented at conferences around the world, is the author of a number of peer reviewed academic journal articles and works actively in the consulting industry. Professionally, he has a unique ability to interact, engage and develop people from senior management to rank and file employees and impart his knowledge in a manner that leaves a lasting impression on the people he teaches. I would highly recommend David as the all round business professional who is able to blend academic qualifications, business knowledge and its practical application across a number of business disciplines.

Michael Cherry, Trusted Advisor & Adjunct Professor

David combines an exemplary understanding of current management concepts and theories with a very strong business acumen – a very rare blend indeed. That is, not only does he have a scholarly understanding of business concepts, he can and does put them into effective practice. He would be an asset to any business school seeking to provide their students with a rewarding and engaging learning experience. David’s strong collegiate spirit with his peers (he is very generous with his time and attention) is also noteworthy. I have no hesitation recommending David for any role where he believes he can add value!

Professor Peter Steane msc, Company Director & Emeritus Professor

David’s research into change management in the non-profit sector makes a significant contribution to what we know of the sector and how to initiate effective change that has long-term success.

Dr. David Paul, Executive Advisor to C-level leaders in Mindfulness; Transformational Change and Leadership

David is one of the few gifted facilitators who can make the complex, simple. This is a gift which few possess. David has consulted and published in the field of Change Management. Few have actually studied and conducted research on Change and I fully endorse David both as a leader and consultant of change. Any organisation looking to solve complex issues in the fields of change and/or finance, look no further! 

Lou Bacchiella, CEO, Metro Assist 

“Overall, I believe David’s presentation answered all the key questions around the proposed move to a Company Limited by Guarantee. The presentation was highly relevant, put things into perspective, and provided some challenges in terms of our future visioning. The presentation clarified any questions our Board members may have had around; why become a Company Limited by Guarantee; what does it mean in terms of Director’s responsibilities, and the role of the Board. There is great clarity in the way David presents the information and his outlining of the environment of NFPs.”

Kamalle Dabboussy, CEO, Liverpool Migrant Resource Centre

“I have worked with David on a Governance change process as part of another large NGO and recently with the Board of Liverpool MRC. David has been able to work with a group of people bringing in Knowledge, expertise and ability to produce comprehensive but concise outcome. He is able to add value to a complex process, making it easy to understand and taking the team along with him, with his professionalism and focus on the subject at hand. It was a pleasure to work with David.”

Tess Parker, Chief Executive Officer, Avenues Lifestyle Support Assoc. Inc.

“Following a Board Workshop on the integration of Strategy and Risk from a board’s perspective “I think one of the greatest challenges is what the Board does once the workshop has been held. What resonates with them to the point of action and what things do they put aside? Some members of our Board have a renewed ‘fire in the belly’ whilst others are deafeningly quiet. Looking forward to the months ahead. Thank you for your energy and inspiration!”

Cathie Craigie, Executive Director, First Nations Australia Writers Network (FNAWN)

The data collection process undertaken was flexible, appropriate, and sensitive to the needs of operational staff.
