What stood out for me in particular: Intensive pace – yet never overwhelming or chaotic. Strong, practical content – full of depth, relevance, and clarity. Engagement & communication – open, responsive, and truly attentive to participants. Professionalism without stiffness – expert-level delivery, but with warmth and ease. No pettiness, just substance – focused on what really matters. Sense of taste and balance – great judgment in choosing what's worth emphasizing. Top-notch presentation & preparation – smooth structure, great visuals, precise language. Genuine responsiveness to participants' requests – rare and deeply appreciated.
