What my clients say about me
“This transformative program helped me explore my strengths, values, and personal barriers. Through the coaching sessions with Mariana, I was able to build self-awareness and unlock my full leadership potential. The insights I gained on how to better engage with and coach my team were invaluable. I also learned how to have honest, productive conversations around performance and what I need to embody as a leader to foster a culture of trust and growth within my team.”
— Kirill Kavelin, R&D Lead van Oord Group
“As a team leader, I knew we had talent—but we weren’t working as one team. Roles weren’t clear, conversations stayed on the surface, and trust was limited. That changed through our offsite and coaching journey with Mariana.
We gained clarity on what we wanted to achieve this year—and, more importantly, how we would do it together. We defined roles and responsibilities, and we learned how to communicate more openly, give real feedback, and support one another. For me personally, one of the biggest shifts was learning to lead with more vulnerability. That created space for the team to do the same. Trust deepened, and collaboration followed. We walked in as individuals with a plan. We came out as a team with a mission—and the confidence to deliver on it.”
— Wendy van der Veen, Team Leader External Communications, Gemeente Bloemendaal
“Before working with Mariana, our leadership team was struggling with low trust—both among ourselves and with our direct reports. Through her coaching, we learned to be more open, vulnerable, and accepting of each other. Mariana helped us create space for honest feedback and meaningful conversations. As trust deepened, so did our ability to collaborate and perform at a higher level. We came out of the experience not just more aligned, but more capable as a team. We turned a low-trust leadership team into a high-performing unit—more honest, more aligned, and delivering real results. When leaders grow, business moves.”
— Niels Meerkerk, Regional Director Buko Infrasupport
"Working with Mariana of Trust Command was a turning point for our executive team. She helped us create a clear, shared vision and a realistic roadmap to get there. But what made the biggest difference was how she built trust within the team—something we hadn’t been able to achieve on our own. Mariana brought clarity, structure, and a calm confidence that made tough conversations feel productive. We left the engagement aligned, motivated, and ready to move forward. I’d recommend Mariana to any leadership team looking to level up fast."
— Jim Jongh, Manufacturing Executive Lead, Oil & Gas
"My trajectory with Mariana of Trust Command was truly transformative. Through her non-conventional coaching style, I gained a deeper awareness of how to mobilize and engage my team more effectively. I developed greater trust in my own leadership abilities and felt like I finally unlocked my potential. With Mariana’s guidance, I crafted a clear vision and a focused plan to lead with more confidence and intention. Her approach challenged me in the best way—insightful, direct, and always supportive. I grew not just as a team leader, but as a person."
