After Hours

I enjoy spending time in the outdoors and sailing ( I maintain my membership in the German blue water yacht club “Kreuzer-Abteilung”). With my family, I like to cook on weekends, hike, or catch a Saints game. Above all, I am passionate about learning and one might find me with my nose in a book, or trying myself at a new skill.
