FAQs

Strict confidentiality between coach and leader is essential for psychological safety and genuine behavioral change. In sponsored engagements, we conduct a structured three-way alignment conversation at the beginning of the engagement with the leader, their direct manager, and their People Partner. This meeting aligns on strategic business priorities, key competency focus areas, and observable success metrics.
However, everything discussed within individual coaching sessions remains completely confidential between the coachee and myself, adhering to strict International Coaching Federation (ICF) ethics. We hold a mid-point and final calibration meeting to evaluate progress against business outcomes, where the leader themselves leads the narrative of their own growth.

We employ evidence-based, system-level diagnostics tailored to the organization's needs rather than applying a rigid, one-size-fits-all formula.
• Integrative Enneagram: This comprehensive diagnostic helps uncover core motivational drivers, stress behaviors, communication dynamics, and unconscious leadership blind spots.
• Qualitative 360 Stakeholder Interviews: Nuanced, 1:1 stakeholder conversations that capture direct feedback, cross-functional friction points, and unwritten cultural expectations.
• Internal Performance Data: Where appropriate, we integrate internal reviews to ground our development goals directly in company context.

Individual executive engagements typically span 6 months and include 10 to 12 one-on-one sessions (typically bi-weekly for 60 minutes). This duration provides sufficient space to diagnose root causes, stress-test new behaviors in real-time business situations, and measure tangible leadership ROI.

While individual coaching elevates the single leader, team coaching and facilitation elevates the entire operational system. When organizations undergo rapid scaling, restructuring, or post-merger integration, cross-functional connective tissue often frays. Team engagements range from half-day intensive alignment sessions to multi-day strategic retreats and longitudinal 6-month cohort series. We focus on establishing team charters, resolving cross-functional friction, aligning on high-stakes roadmaps, or mapping collective team Enneagram profiles to optimize collaboration and psychological safety.
