N.F., Executive Leader

Mirella has perfected the art of executive coaching by combining her deep knowledge of mental schema, her understanding of business operations and structures, and her ability to quickly grasp her coachees’ abilities, capabilities and environment.

Throughout my coaching journey with her, she challenged me tremendously and encouraged me to experiment new ways in showing up and in deploying my leadership fully and authentically. This was always done with respect, kindness, and support.

HR Assistant, Dart Aerospace

Stefano Di Lollo and the Papillon [MDC] team did a fantastic job training members of DART’s executive team! I will absolutely keep Papillon [MDC] in mind for future leadership training.

Marco Quintana, Mexico Plant Manager

The portion of this [leadership] program that resonated with me most was the focus on development strategies—particularly the distinction between managing, coaching, and mentoring—because it highlighted how each plays a vital role depending on the context. It was incredibly valuable to share experiences and gain an external perspective beyond the day-to-day company environment. Stepping back allowed for a broader, more objective view. [Stefano Di Lollo] brings deep expertise to the conversation and demonstrates a remarkable ability to adapt to any situation or context.

HR Director, Alstom

Stefano, thank you for the group and pod coaching sessions—and for bringing such energy and patience to each one. It was extremely helpful.

Anonymous, PWC

I love Stefano [Di Lollo] as a trainer. He’s highly engaging and consistently provides relevant examples that help learners connect with the material and see how it applies to their day-to-day work.

M.O., Aerospace

This training was incredibly helpful, especially for someone like me who occasionally lets emotions interfere with conversations. I was able to get great tools for receiving feedback and also strategies for dealing with difficult situations and personalities. A very interesting training that I believe is a MUST for everybody, even for those not in leadership positions. Excellent delivery of the content, and entertaining too! Thanks, Stefano.

This course was truly excellent, and I’ve already recommended it to others at Pratt & Whitney — and even to people outside of my organization. Thank you to Stefano Di Lollo — his facilitation and “coach approach” are truly amazing. He makes it look easy.

Aviation & Aerospace Specialist, Senior Director, Pratt & Whitney

This isn’t my official testimonial just yet – – – I’m only halfway through the Impactful Conversations program, but I felt compelled to share some thoughts with you now, Stefano. I regularly seek out leadership training as part of my personal and professional growth, and while many programs offer something useful, none have resonated with me quite like this one facilitated by you. From the engaging case studies, your thoughtful artwork & props, to your powerful storytelling and real-world examples, every element is perfectly timed, relevant, and deeply impactful (just like the program name). I’ve never truly looked forward to trainings before but I’m genuinely looking forward to the sessions ahead. How’s that for “feedback”? 😉 Thank you, Stefano!

AlLe, Pratt & Whitney

I signed up for this course several months ago after hearing great “feedback” about Papillon [MDC] programs, like Navigation Coaching. Honestly, I was mostly drawn in by Papillon [MDC]’s reputation and by Stefano [Di Lollo] as a unique facilitator. I had also heard wonderful things about Mirella. Since I’m still relatively new to the company, I haven’t had the chance to attend many leadership trainings here — which is why I took the time to ask around.

The topic didn’t particularly interest me at first, because while I don’t have decades of experience, I felt I already had a solid handle on feedback. What I didn’t expect was how eye-opening the course would be. The tools offered went far beyond the typical “hamburger” method. Stefano truly delivered — his expertise came through clearly in his examples and visuals. I really appreciated the spontaneous role-play Stefano surprised us with.

In the end, I’m genuinely glad I took this course. Thank you!

Mhouar Bilal, Machining Operations Planner, Pratt Canada

I recommend this course because it offered me new tools and fresh perspectives on how to give more effective feedback—even highlighting things I was already doing well without realizing it. Stefano [Di Lollo], the facilitator-coach, shared thoughtful and relevant personal stories at the perfect moments. This course is a valuable resource for anyone looking to grow as a manager or leader when it comes to giving feedback. I also truly appreciated the powerful visuals that supported the content—I’ll definitely be referring back to the manual whenever I need a refresher.

Director, Pratt & Whitney

I’m going to strongly recommend the course. Thank you, Stefano, for the great sharing of examples. I really liked your touch of humor. I also appreciated the introspection on blind spots. I’ve already identified a situation to address with a direct report, and I’m going to use the method. It’s going to help me become a better leader. Very good course!

Daliana

This program was an excellent refresher in leadership essentials as well as an introduction to leadership concepts beyond the essentials. Stefano addresses any leadership challenge brought to his attention super well with well-derived and relevant conclusions and solutions. Kim provides good follow-up questions. The last two days of the workshop were very interactive and efficient.

Anne-Sophie

This program provides the opportunity to learn in a safe space. It also simultaneously allows leaders to create strong connections which is precious. The level 2 portion of the program is energizing. We deepened our team connections while revisiting key concepts from the module, exploring new ideas, and seeing how everything fits together through practical application. Thank you!

Director at Alstom

This training was very beneficial. For me, the topic of growth mindset resonated with me the most as it was very helpful in gaining self-awareness. During Level 2, the role-playing and open dialogue were particularly enjoyable and very helpful. Stefano Di Lollo was engaging and very easy to pay attention to. He creates a comfortable environment to share one’s vulnerabilities and learn.

Senior Leader, Alstom

This program was fantastic and the facilitators were fantastic! I found the last 2 days to be extremely positive, and I enjoyed every interaction. I also really enjoyed the pod coaching because it provides much insight while listening and then contributing without resolving the issue for the person is more powerful than I could have imagined. Asking open and powerful questions remains one of my goals to work on. The facilitation style was really fun (THANK YOU, Stefano + Kim)! This program truly provided me with an opportunity to reflect on ME and how I work with others!

Alstom Leader

I found the content on growth mindset challenging to apply which is why it resonated with me and spending time in a training like this one helps without a doubt. The facilitators were very articulate and able to establish a good rhythm.

Anonymous, Senior Leader / Alstom

This program helped me analyze and navigate “sticky situations” (I can’t help but laugh when I think of Stefano’s artwork of the gum stuck under the dress shoe). I appreciate the strategies to use specific sequences and structures to guide our thinking in difficult workplace moments. The facilitators showed great vulnerability and knew how to ask the right questions. It’s an advantage to have facilitators who are also experienced executive coaches.
