Andrew Ziesemer – Managing Director/Toowoomba Manager

I was born and raised on a Western Darling Downs grain and cattle property until attending boarding school in Toowoomba. 

After leaving school I started work on the family farm and then spent time managing a sales and distribution outlet for a corporate agribusiness company. My wife, Katie and I started Anka One (previously known as Anka Ag) in 2008.

John Hegarty – Sales and Agronomy Miles

I grew up on the black soil plains of the Darling Downs at Pampas, Qld. I have always worked in agribusiness with the majority of time as an Agronomist and with a short period in Machinery Sales. I specialise in broad acre grain crops. I enjoy the people in the Western Downs and decided to move back west in 2010 to establish Anka One at Miles.

Marcia Smith – Administration 

Growing up in western Queensland and having worked in various rural industries ranging from livestock and pastures, to cropping and grain has provided a great background for my role in sales and agronomy at Anka One Dalby. I enjoy working with farmers, and have a strong interest in science and the environment.

I grew up working on family properties around Dalby and Cecil Plains.
