Executive Leadership

Thomas Aarup Christensen
CFO | LEGO, Denmark
Team and leadership coaching with Leni at C-MOMENTUM has been a game changer for my professional life. I went from facing many challenges to experiencing my work as fun and fantastic. It also enabled me to take my career to the next level.
I started working with Leni as my coach because I had challenges in my leadership style that impacted employees and customer satisfaction. One year after my coaching program ended, customer pulse had increased to the top of the industry and employee satisfaction was the highest in the company.
Working with Leni was very intensive, and she truly helped me work towards the behavior changes I needed. She set clear direction, gave time for reflection, challenged me to deliver, and was there with empathy when it was difficult. Leni is still often on my mind. When I face challenges, I return to the behaviors we defined together and remember her with gratitude. I can truly recommend Leni for leadership coaching. She has helped me create significant game changers in my professional life, bringing it to new levels.

Working with Leni for over six months was nothing short of transformational. She quickly connected on a human level, dug deep to uncover my real needs, and built a clear plan that turned insights into action. Every session moved me forward—and she kept me honest about my progress. Leni is an exceptional coach and a wonderful person, well worth the investment of time and energy.

Managing Director | Sony Music Norway
When we began our coaching work, I was running on empty after a long and demanding period. I needed a trusted sparring partner who could offer perspectives, support, and practical tools to help me find the way forward. Through the process I regained my drive, balance, and joy, and I felt more grounded and self-assured: calmer, clearer, and more intentional in how I lead both myself and others.
Coaching gave me energy, strengthened my confidence and authority, and I’m taking all of this with me as I develop my team and deliver results together. It has been deeply reassuring to have Leni by my side: solid, experienced, and warm. Wise, with a good sense of humor, and exceptionally skilled.
Team Development

Axel Christophersen
Museum Director | NTNU University Museum
NTNU University Museum has used C-Momentum AS for team development courses for our employees. Through active and challenging involvement, the program provided significant learning outcomes and strengthened social relationship building.
The setup and delivery were based on high professional competence and excellent facilitation. Not a minute was wasted! Afterwards, we’ve seen how much we’ve been able to take with us to make a good day at work even better.
Highly recommended!

Jan Petter Opedal
CEO | Danica Pensjon, Norway
As a relatively newly established management team, we experienced that we were not reaching our full potential. Communication did not flow, and we were too respectful of each other.
Through working with C-MOMENTUM over 18 months, we saw progress across every single parameter we measured, between 5 and 25 percent. The facilitation brought the right issues to the table and helped us commit and move forward. Our team has taken big steps as a result.
I give them my best recommendation!
