Bernadette Willetts
Laboratory Manager

Her background in customer service has aided her in being an adaptive, patient learner as well as intentional yet efficient despite working in a busy environment.
Bernadette’s role means that she upholds our collection standards as well as makes sure that our donors are catered to and that our plasma is clean and safe. She enjoys tackling the daily challenges that arise from the nature of this work and is invigorated by partaking in a job where prioritizing equine welfare leads to bettering the health of a greater equine population. When she’s not at work, Bernadette enjoys competing on her local rugby team, competing with her horse, Jacob, spending quality time with her dog, and connecting with friends and family.
