Andrew Meredith

Head of Customer Care

I began my career with YorkTest back in 2007 and during that time it has been a fantastic company to work for, I really enjoy working at YorkTest. I started life as a Customer Care Consultant. During my time at YorkTest, I have been promoted several times, from Senior Consultant, Team Leader through to my current role as Head of Customer Care. The training and support the company afforded me has been the key to my success. It's fantastic when we talk to our customers, building relationships along the way, supporting the customer and making a difference to their health and general wellbeing. This for me is the most rewarding part of my job.
