Diana Johnston Ledezma
Head of Quality at DR Wakefield

Diana’s connection to coffee began at a young age, having spent her childhood visiting her grandfather who was a coffee farmer in Mexico. Her first job in coffee was during high school as a Barista for Starbucks and it was here her interest in coffee grew, particularly from a sensory perspective. While at University she continued working in coffee, eventually becoming a company trainer for Peet’s Coffee and Tea in Berkeley, California. Now with 15 years of experience in the industry working across various parts of the business from quality control to roastery to green, she is a regular on the coffee competition scene. 2017 saw her compete in 10 competitions including all UK SCA comps as well as Coffee Masters, Aeropress and more. Certified as AST in both Green Coffee and Sensory, Diana is the Head of Quality for DRWakefield, a green importer based in London.
