Development

Team Effectiveness Workshops

Workshops are built around your team's specific needs, not a generic curriculum.

• Trust & psychological safety

• Constructive conflict management

• High-impact meetings

• Engagement & motivation

• Decision-Making Under Pressure

• Coaching skills for leaders 

Bespoke Offsite Facilitation: 1-2 day offsites designed around your team's TQ diagnostic, so time in the room targets your real friction points, not a one-size-fits-all agenda.

Every workshop is built around your team's actual diagnostic data, so the time in the room is spent on your real friction points not a one-size-fits-all agenda. 
Executive Coaching

One-to-one coaching that starts with data, not a generic intake conversation, every engagement follows directly from psychometrics or 360° result.
Phase 1

Assess

Hogan or 360° feedback establishes the baseline: strengths, derailers under pressure, blind spots.
Phase 2

Debrief & plan

Results translated into 2–3 priority behaviours tied to real business outcomes, not a generic report walk-through.
Phase 3

Sustain

Regular sessions over 6–12 months with stakeholder check-ins, so change is visible beyond the coaching room.

Format options

Standalone executive coaching, or embedded coaching for leaders moving through a team diagnostic, so individual and team level work reinforce each other rather than running as separate tracks.

I don't coach off a generic competency model. Every plan starts with your assessment data.
