What others say about me

Theresa coached me through my first 6 months as VP of Product at a new company, and working with her gave me the confidence and clarity I needed to succeed quickly. She was instrumental in helping me craft a 30-60-90 day plan that prioritized high-impact wins while I navigated the complexity of a new organization.

I appreciated Theresa's thoughtful approach to bridging the gap between strategy and execution. Her guidance was critical as I established new processes, prepared for my first board presentations, and structured the team for growth. Her coaching allowed me to accelerate my ramp-up time and establish trust with stakeholders much faster than I could have alone. I highly recommend Theresa.

Emily Wanless

Vice President Product @ SaaS B2B company

We have worked with Theresa twice during critical phases in our company: first as part of an important organizational development process, and later to support the build-up of our software business. In both mandates, she initiated significant changes with great clarity, structure, and strong execution. At the same time, she strengthened our leadership team and encouraged entrepreneurial thinking. Together with our team, she laid the foundation for a viable software business – with a clear business model, a structured product management approach, and an integrated go-to-market concept. I value Theresa for her strategic strength as well as her ability to address complex topics in a pragmatic and solution-oriented manner. Working with her was extremely valuable – I would engage her again at any time.

Sonja Wiedemann

CEO & Managing Shareholder @ Sensor-Technik Wiedemann

Working alongside with Theresa for four years, both of us reporting directly to the CEO of a €600M+ business division, has been one of the most inspiring and professionally rewarding experiences of my career. She is the rare combination of hands-on pragmatist and visionary leader — someone who not only sees what's next but knows exactly how to get there. As an example, together, we conceived and launched a groundbreaking digital service for the Energy Industry — a completely new category of offering, both in terms of business model and technical architecture. Under her strategic leadership, this innovation not only achieved an exceptionally high operating result but also set a new benchmark for digitalization in a highly traditional industry. It was bold. It was complex. And she made it happen. What impressed me most? Her ability to translate abstract strategy into executable action — quickly, decisively, and collaboratively. She moves seamlessly from Board-level discussions, building long-term company development strategies, to operational implementation, always with a strong sense of purpose and integrity. In a global matrix organization, she is a great to have senior servant Leader. Would I recommend her? Without hesitation — and without limitation. Any company serious about driving innovation, navigating digital transformation, integrating AI in daily business or shaping long-term strategic growth would be lucky to have her on board as part of the Leadership team. She's not just an experienced senior manager. To me, she’s a force multiplier.
