Coaching leaders and professionals at career crossroads to achieve lasting, real impact.

HEY! I'M JAN. Over the past 25+ years, my journey took me step-by-step from frontline roles in finance and operations to executive leadership across Europe and the Americas. Along the way, I’ve experienced both the fulfillment and the real friction that come with organizational change, career crossroads, and demanding corporate environments.


Originally from the Netherlands and now based in Texas (USA), my international career and exposure to diverse cultures have deeply shaped my approach to leadership and coaching. Today, my focus is to serve as a trusted sounding board and partner—providing a grounded, supportive space to help you step back, gain perspective, and lead with clarity and intent.


Who I Support: Professionals stepping into new management roles, mid-level leaders finding their stride, and senior executives navigating complex transitions.


What I Do: Clarify priorities, uncover blind spots, align leadership style with core values, and build the competencies needed for steady personal and professional growth.


How I Work: Pragmatic, thoughtful, and collaborative—anchored in honest self-reflection, deliberate choices, and steady, actionable steps.


If you’re ready to take the next step in your leadership or career journey, I would be honored to work with you.
