Our Client Endorsements

The value in engaging Jeremy to help develop and launch our strategy & vision in Australia and the USA has proven immeasurable. The project has been an outstanding success. Jeremy’s family business experience and genuine interest in our business is why we work with him, over other advisors.

Markus Preston, President

Preston Hire Group

Jeremy never came across as a “know all consultant” or that he had all the answers, but rather he knew how to ask the right questions! His hands-on approach showed us how to be far more profitable and ultimately increased our business valuation by many multiples.

Martin Collett - Managing Director

Eurofins Agrisearch (Australia)

Jeremy is extremely thorough and reliable. He was quick to detect what was holding our business back when we engaged his services, early in 2015. If you are seeking a no-nonsense, numbers-driven advisor, who understands how to get people on board with your performance improvement initiative, I can highly recommend Jeremy.

Guenter Hauber-Davidson, Managing Director -


Jeremy led our leadership team through a creative process that got us out of our “business as usual” thinking and generated solutions with real impact. Working with busy scientists is often a challenge, however Jeremy managed this in a professional and personable style that had respect for all involved. The creative process opened up the dialogue and gave us a new sense of purpose.

Emeritus Professor Maree Gleeson OAM - Executive Director

Hunter Medical Research Institute

Jeremy is extremely professional, knowledgeable and practical when it comes to helping clients shift to new business models & technologies. He has a robust understanding of the health and aged care sector and is a strong advocate for systems and leading edge processes for change management. His management consulting capacity is enormous and we highly recommend him.

Cynthia Payne - CEO

SummitCare (Australia)

Having myself led major transformation projects globally, I am impressed with Jeremy’s extensive wisdom and experience, especially how he has embraced a systems-holistic view of organizational change and improvement. Indeed, it is because of his systemic knowledge that he can help clients see the bigger picture of long-term success, and then facilitate their process in getting there.

Ralph Kilmann - George H. Love Professor of Organization and Management

University of Pittsburgh

deCONSTANTIN was recommended to me based on their track record in business turnarounds. We required an independent and objective view of our business operations. Jeremy and his team quickly turned around our operations (where many others had tried and failed previously) and embedded their processes & disciplines to ensure we sustained the turnaround.

Chris Kelleher, CEO

Tunra Bulk Solids

The Mater Hospital always has been a very good hospital with great people but like any organisation there is room to improve. We now have the system to set targets and hold people accountable for meeting their targets. Before Jeremy’s program the system and discipline for target setting was largely absent.
