I have been involved in the agricultural industry for over 20 years and the one thing I enjoy above all else, is getting the opportunity to meet with growers from across the state and learn about their stories and see the passion they have for what they do. Having grown up in a small regional town, I understand the importance that growers have to all of the small communities around the country, and now living in the city I enjoy educating my children on the importance growers have on our lives from the food we eat to the clothes that we wear. Away from work, most weekends are spent involved in my children’s sports and being a Fremantle Dockers supporter I am usually hanging out for the start of the cricket season.

I have been fortunate to work in various roles across the WA ag industry, including agronomy, soil nutrition and quality assurance. Working for Nufarm I have the opportunity to get back out into the paddock, helping to overcome individual problems with quality, Australian made products. As my family is young, I work on a part-time framework. I am so lucky to be able to combine the things that I am passionate about.

Born and raised in the country, I have spent my entire working life in agriculture. I enjoy working in an industry that is constantly evolving, it is always presenting great opportunities and challenges. Working for Nufarm allows me to help growers and customers find practical solutions to these challenges, to enable them to grow the best crops they can.  Away from work I am a keen follower of horse racing and cricket and I am partial to a good craft beer and homemade salami.

I have been involved in Agriculture for the last 22 years, with it beginning at Muresk in Northam, W.A. In that time I have worked in Agronomy both in crop nutrition and protection roles, most recently in the UK Ag industry. Working closely with growers and customers to find sound economic and practical solutions is my passion. Being involved in local junior sport with three young sons playing cricket, football and wanting to go fishing, keeps me looking for time.
