What people are saying

  • I can wholeheartedly recommend Lena! As a full-time professional with additional volunteer commitments, filing my tax return is often a real challenge—especially when it comes to deducting privately funded travel expenses as a board member. Lena provided tremendous support with her expertise and strategic guidance. But she’s far more than an excellent tax advisor—she also serves as a mentor and mental coach, helping her clients not only with financial matters, but also with achieving their professional and personal goals in a strategic and sustainable way. Her holistic approach empowers you to navigate challenges with confidence and gain fresh perspective. In addition to her expertise, I truly value her warm and professional manner. If you're looking for reliable, forward-thinking, and practical advice, Lena is the perfect choice!

  • In just a few sessions, Lena Backhaus helped me get back on track—both in my athletic performance and in my business. I was struggling with doubts about the structure, purpose, and success of my company, while also feeling stuck in my training. Lena provided me with a clear strategy to regain focus and direction. That had a positive impact not only on my workouts but also on my business decisions—and it still does. For me, it marked the beginning of my personal comeback. A clear recommendation for Lena Backhaus!
