Diana Dolejší


She first tasted speciality coffee at our basic course in 2015. The whole culture fascinated her so much that the day after the training she went with her CV to the Double B café and roastery in Prague. After less than two years she moved to a more busy and lively café Ema espresso. In 2018, she anchored in Onesip coffee as a barista and manager. She still appears there several times a month with a smile behind the bar.

During her coffee journey she also helped at the Brewbar on Prague's Náplavka, coffee festivals, and in the Candycane coffee roastery.

Since the end of 2020, she has been leading all trainings with us and has also started helping out at our roastery, The Naughty Dog. She prefers filtered washed processed coffees and a croissant dipped in it.

She is young and shy, but she loves to play a lot.
