Built for Organizations Where the Work Is Too Important to Leave to Another Report.
C35 is a Collective of senior Practice Leaders — strategists, operators, and specialists — assembled around the challenges most consultants are not built to hold. We exist for leaders who need real partnership, not another deck.
Your Partner For When Work Gets Too Important To Get Wrong.
C35 Collective is not a firm you hire to write a report. We are the senior team you bring in when the stakes are high and the path is unclear — when a wrong call costs more than a missed quarter, and clarity has to come before commitment.
We work across strategy, leadership, operations, security, mission, and digital — bringing coordinated expertise to challenges that refuse to sit inside one lane.
Vision Is Not The Problem. Structure Is.
Most leaders we work with have vision, drive, and a team that cares. What they do not have is a structure strong enough to carry it. Priorities blur. Handoffs break. Decisions stack on the leader. Growth exposes fault lines that a smaller organization never had to feel.
- Strategy sessions produce plans that never quite launch.
- Your team is aligned in the room and drifting by Friday.
- You are the escalation point for problems others should own.
- Every new initiative pulls the same three people thin.
- You know something has to change — you just do not have time to figure out what.
Built Because Passion Without Structure Burns People Out.
C35 was founded by Dr. Greg McQueen after three decades of watching mission-driven leaders — in enterprise, government, faith, and community — pour themselves into work that outgrew the systems built to hold it. Great leaders do not fail because they stop caring. They fail because they never got the structural partner they needed.
The Collective was built to be that partner. Not one voice in the room, but the right voices — coordinated, senior, and accountable to outcomes, not deliverables.
When Purpose Is Paired With Structure, Impact Compounds.
Every framework we build, every engagement we run, every leader we develop — is in service of that equation.
Why A Collective Works When A Single Consultant Cannot.
Complex organizations do not have single-lane problems. A strategy issue reveals a leadership gap. A leadership challenge exposes an operations breakdown. A security incident becomes a culture conversation. One consultant, however talented, cannot hold that surface area alone. A Collective can.

Six Non-Negotiables.
The person in the discovery call is the person on the engagement.
One brief. One lead. Multiple experts working from the same page.
Every recommendation is scoped to your calendar and your capacity.
We serve leaders in high-stakes contexts. Confidentiality is the floor.
You will hear what we actually see. Kindly. Directly. Without theatre.
We optimize for what changes on Monday, not what looks good on a wall.
Training Designed for Real-World Leadership.
Our training practice teaches leaders how to lead the organization they actually have, not the one on the org chart. Every intensive is built for the specific pressure your team is under — and calibrated to produce different behavior on Monday.
