Your sparring partner
I help leadership teams make better strategic decisions, handle difficult relationships, and change how work gets done.
My work can begin with one strategy session, workshop, or coaching conversation, and grow into ongoing strategic sparring, leadership programs or talent and skill development.

WORK IN PRACTICE
A fast-growing organization brought Gary in to improve how teams learned and worked. As leadership and cross-department dynamics surfaced, the work grew into ongoing strategic sparring.
Scale-up · continuing advisory relationship
An L&D team asked Gary to redesign assertiveness training for leaders. Participant word of mouth led to further coaching, training, and program design.
Large organization · repeat leadership work
Gary is an absolute wizard on stage.
Lead L&D Development
An amazing executive coach and sparring partner.
Managing Director
It’s very useful to have him on call for ‘anything behavioral’ that we could fix ourselves but nowhere near as fast and elegantly as he can.
Head of People & Culture
He cuts through organizational fog faster than anyone I know.
COO
Exceptional facilitation under pressure. He has a kind manner, with effective influence.
HRBP
Well-done Gary. You adapted to our needs when the training took a turn. Thank you.
Team member
I am a big fan of Gary’s live sketching visuals.
Manager Operations
The Why
I focus on how leaders and teams think, speak, and act, because better behavior inside an organization changes what that organization can achieve outside it.
“Sky” is what you want to achieve. “Lake” is what happens beneath the surface: your behaviors, patterns, and unknowns. Skylake connects the two.
What I bring to every assignment
New environments reveal what you not yet know. That exposure creates learning, new ideas and possibilities.
Action creates motivation. Not the other way around.
Let's get to work.
People achieve much more when they actively help one another succeed, across teams, silos, and reporting lines. Collaboration beats competition in organizations.
I question “good enough” and help people raise their standard without losing sight of their goals.
Skylake doesn’t just imagine a better world. We work towards it by helping people lead better, work better together, and turn intentions into progress.

A practical first step
Start with a leadership meeting, a focused intervention, or ongoing strategic sparring. I listen, notice the dynamics, and clarify what deserves attention first.
