I am an independent farm consultant operating for over for 25 years in the Waikato region. My interest is in optimizing farm systems with a strong practical viewpoint so that the objectives of the farm business are met. To compliment this interest, I have undertaken the courses that allow me to formally report on dairy effluent systems.

These reports provide the independent benchmark for the ongoing farm operations of the effluent systems. As well there will be specific situations such as changes of farm ownership or sharemilking that require a historical standard of the effluent system to be recorded.

For over three decades I have worked in New Zealand's innovative dairy industry as a milker, dairy farm own, dairy livestock service business owner, and I have an agricultural science degree.

From this varied industry experience my point of difference is that I have theoretical, practical, tehcnical and management skills.

It can be difficult to assess different on-farm options available relative to requirements. My instincts and calculations assess what practical on-farm solutions are available. This involves adapting to farmers' preferences, diverse market changes and compliance issues.

Industry-wise I am a negotiator, go-between and advisor. With this knowledge and my natural empathy, I find outcomes to match clients' objectives.
