Alice came onboard with Ballance as the Nutrient Specialist for the Timaru-Oamaru region in October 2023. Growing up on her family's intensive arable cropping farm in Mid-Canterbury, Alice went on to complete a Bachelor of AgriScience with honours at Massey University in 2014. She has since worked in a variety of roles including rural insurance, dairy nutrition and livestock procurement that allowed her to combine her passion of agriculture and supporting farmers in their farming operations throughout the lower South Island. Alice moved to her partner's sheep and beef farm in Weston in 2018 and has since bred two young kids who enjoy the farm life greatly. In her spare time, she enjoys triathlons, particular the half ironman distance, which means lots of cycling and running as well as being a volunteer firefighter in the Weston Brigade. Alice is passionate about partnering with farmers to drive performance and profitability on farm effectively and efficiently.

Gretchen took up the role of Core Nutrient Specialist role in Coastal South Canterbury in March 2018, and has since taken up the Key Accounts Nutrient Specialist South Ashburton in January 2022.
A South Canterbury local, Gretchen hails from an arable and dairy support farm - which is where her interest in agriculture first took hold. This led her to Lincoln University, where she completed a Bachelor of Commerce (Agriculture).
She also has practical experience working on arable, sheep and beef and dairy farms, and she credits this with giving her a broad understanding of how differing farm systems work and building her knowledge base.
Gretchen enjoys working in the agricultural industry, in particular connecting with farmers to both grow her knowledge and help them overcome any challenges they may be facing.
Outside of work, she still likes getting her hands dirty helping on the farm, as well as hiking and water sports in summer.
