Born on the rugged North Sea coast of Germany, a place where locals are known as “Fischköppe” (fish heads) – a bit stubborn, no-nonsense, and used to pushing through the wind. This mentality drives his consulting style: plain speaking, pragmatic solutions, and the ability to stay on course even when waters get a little rough.
“Big 4-level expertise, without the fluff – just clear execution and tangible results.”
Lenny offers over a decade of experience bringing structure and stability to growing businesses. In his years at EY-Parthenon, he specialized in complex carve-outs, integrations, and transformations across various industries like telecom, pharmaceuticals, and manufacturing. Now he helps leadership teams and founders scale their companies without losing focus. His approach is hands-on, data-driven but personable, and tailored to each client’s unique challenges, whether it’s aligning teams, optimizing processes, or building scalable systems.
