He prefers to situate himself in the tradition of drawing and cartooning, even where he uses paint and brush, and feels strongly drawn to the publication form and the reproduced image. He is the author of Sweathearts (Abyme 2024), a typeface and comic book, published by his dear friend, the late John Morgan. 

Born in Košice (Slovakia), Groch has been professionally active as a graphic designer and artist at least since 2013. He first trained in graphic techniques and typography, at Umprum in Prague among other institutions, which he left precociously. From 2019 to 2020, he was a resident at the Jan van Eyck Post-Academy for Art, Design and Reflection in Maastricht. Among his frequent collaborators are Tim+Tim Studio, Jakub Samek, Robert Jansa, Peter Bosák, and Nana Esi (Atelier Brenda).

At the invitation of prof. Natasha M. Llorens (KKH Royal Institute of Art Stockholm) in 2020, he participated in a project titled Art-Rite, reinterpreting the iconic cheap art newspaper from 70s New York. At KKH, Groch was also invited to give workshops and lectures.
