The first season as senior in the Bezirksliga at Fortuna Mönchengladbach was so successful for René that he was bound by the then Oberliga-club 1. FC Wegberg-Beeck. He played five years (1999 - 2005) long in Ober-, Landes- and Verbandsliga. After the first two years Beeck pulled out of the Oberliga back to start over to leagues deeper in the Landesliga. As a result, René came with Beeck to two ascents: from the Landes in the Verbansliga and  in his last game for Beeck promotion to the Oberliga was done perfectly.
