WJE Holdings

I have owned a business and building in the Wiri area since 2009 and have been involved with the Wiri Business Association because of that. Over the years I have attended several of the events and first aid courses that have been on offer and have found these useful for networking and gaining skills. I continue to encourage other businesses in the area to get involved and attend events/courses. Being on the Board is my way of giving back to the business community and I aim to offer insight into things the Association can do to help/assist businesses with issues that affect them.

I am passionate about our local area and know that many great people in the area feel the same way. I grew up, went to school, and live in the suburbs just next door. I have grandchildren growing up in the area, and I would like to know that I can make a difference in helping them grow up in a safe and clean environment. Now I am also working in the area I can see a great future for it after seeing what the WBA have already been doing. I want to give back to the community myself through being a board member. I am excited about the opportunity to work with other board members and make a difference.
