He brings with him a lot of experience with a variety of equipment, quality standards, horticultural knowledge and a hard to beat work ethic.

He has a number of goals and aspirations and knows that being the valued member of the DLGA team that he is, is going to help propel him towards these goals.

Community Partnerships

Part of the Diamond Lawn & Garden Australia mission is to give back to the communities and townships within which we operate. We have partnered with many community organisations, through sponsorships, discounted rates and sometimes, just by being there to help when needed.

Assisting these groups and others, not only enables them to minimise their outgoing costs and use their money for more important things, it also makes us feel pretty good.
