Accelerating leadership
and team effectiveness.

The best version of your leaders and teams is already within reach. The work is about surfacing it.

The challenge

Your leaders are capable. Your teams are experienced.

And yet, you sense there's more potential. Decisions that seem straightforward get revisited. Conversations that need to happen don't. Leaders who should be driving execution are getting pulled in too many directions.

This isn't a capability problem. It's a clarity problem — about how your leaders and teams are actually wired to think, respond, and work together.

of Fortune 500 companies use the Hogan Assessment framework that underpins Trellis's methodology

The approach

Science-driven insight. Practical behavior change.

Using validated behavioral science, Trellis identifies the specific patterns shaping how your leaders decide, respond under pressure, and show up for their teams.

The path forward isn't another strategy or training program. It's a clearer understanding of the habits that got you here — and which ones may be quietly limiting what comes next.

improvement in team effectiveness linked to structured development and debrief processes

Services

Two ways to work together —
both grounded in the same methodology.

01

Leadership assessment and coaching

One-on-one work with leaders navigating expanded scope, increased complexity, or significant transition. Uses validated personality science and stakeholder input to build a precise, personalized development roadmap.

→ For leaders
02

High-performance team development

A structured engagement that examines how a team's collective behavioral profile shapes decision-making, conflict, and execution — and builds a shared framework for sustained performance improvement.

→ For teams
How it works

A structured process.
Personalized outcomes.

Every engagement follows a repeatable, research-backed structure — combining validated assessment, structured interviews, and stakeholder input to produce insight that is both rigorous and immediately actionable.

Phase 01 — Assess

Surface the full picture

Hogan Assessments combined with behavioral interviews and stakeholder conversations establish an accurate, data-driven view of how leaders and teams currently operate.

Phase 02 — Translate

Connect insight to outcomes

Findings are synthesized into a Leadership Insight Report and debriefed with the leader, manager, and HR partner — co-creating a development plan grounded in the data.

Phase 03 — Apply

Sustain behavior change

Ongoing coaching and structured follow-up sessions translate insight into durable shifts in how leaders and teams actually operate — not a one-time event.

In their words

About Tyler Carey

Built from the inside out.

I spent the last four of my nine years at Amazon Web Services working directly with executives on leadership assessment and development. I watched what happened when leaders received targeted support at critical inflection points - how they made decisions differently, led with more clarity, and navigated complexity without burning out.

When Amazon asked me to relocate to keep that role, I made a different choice. I decided to see if I could build something of my own around the work I was most passionate about. That's Trellis.

I've seen what becomes possible when leaders and teams create space to step back, reflect on what’s working, and identify the subtle shifts that can dramatically improve how they lead and operate together. The potential was always there. The work is about surfacing it.
