The people I admire most all share a common set of traits: they are highly ambitious, smart individuals, yet incredibly humble, respectful, and open, in all circumstances, and with everyone. I could not imagine working in an environment which is any different, and from my very first conversation, Cranemere stood out.

Besides the uniqueness of the team and culture, I joined Cranemere because I am passionate about the process of building and growing businesses sustainably over the long-term, alongside exceptional founders and management teams. Cranemere has pioneered since inception a new model where business building holds a much more significant place than deal-making only. I’m very excited to contribute to the development of this model further, particularly across Europe.

When I’m not working, I love to explore and engage in outdoor activities. I am fascinated by the power of nature and always feel humbled coming back from a surfing session or a backcountry skiing day exploring unchartered territory. Only sharing these experiences with friends and family can top this feeling!
