HARRIS | ALLISON partners with mid-market leaders navigating complexity, growth, and transformation. We bring senior executive experience directly to your challenges. No junior consultants, no theoretical frameworks. Just decades of pattern recognition applied to your reality.
HARRIS | ALLISON was founded on a simple observation: mid-market CEOs deserve the same caliber of strategic support as Fortune 500 executives. Without the overhead, the junior staffing models, or the one-size-fits-all playbooks.
Our founder, Bill Harris, spent decades as an operating executive before launching this firm. He saw firsthand how traditional consulting often fails the middle market: expensive engagements staffed by recent graduates, recommendations that ignore operational realities, and advice that sounds good in a boardroom but falls apart in execution.
HARRIS | ALLISON exists to be different. Every engagement is led by partners who have sat in the CEO seat, navigated board dynamics, managed P&Ls, and led organizations through transformation. We don't just advise. We help execute.
Bill Harris, CEO
Four principles guide every engagement.
Not aspirational values. Operational commitments.
The partner you meet is the partner who does the work. No bait-and-switch staffing. No learning on your dime.
Recommendations are easy. Execution is hard. We stay engaged until strategy becomes operational reality.
We tell you what you need to hear, not what you want to hear. Candor accelerates progress.
Technology amplifies our work, but judgement drives it. We move fast without sacrificing rigor.
We work with companies large enough to face enterprise-level complexity but without the infrastructure of a Fortune 500.
Leaders navigating complexity who need strategic clarity and execution support without Big 4 overhead. You're past startup chaos but facing enterprise-level challenges. That's exactly where we specialize.
Portfolio companies requiring rapid value creation, operational improvements, or M&A integration support. We bring experienced operators, not just advisors, who understand the urgency of your investment timeline.
Organizations navigating leadership succession, preparing for exit, or professionalizing operations. We help preserve what made you successful while building the systems that enable scale.
Organizational transformation requires more than strategy. It requires structural trust. Our proprietary methodology provides the architecture for organizations to maintain coherence under pressure.
Common data and interpretive frameworks that ensure everyone operates from the same understanding of reality. No hidden information, no competing narratives.
Consistent vocabulary and definitions across the organization. When everyone means the same thing by the same words, execution accelerates.
Aligned rhythms, rituals, and decision-making processes. Predictable patterns that maintain organizational coherence through change.
Our leadership team combines decades of operating experience across industries. Every partner has sat in the seats our clients occupy, navigating growth, managing complexity, and leading transformation.

HARRIS | ALLISON is a strategic advisory firm that serves mid-market CEOs and growth-stage companies with revenues typically between $10 million and $500 million. The firm combines senior executive experience with a proprietary methodology called the Trust Operating System™ to help organizations transform.
We primarily serve mid-market companies with revenues between $10 million and $500 million. These are typically growth-stage, founder-led, or private equity-backed organizations navigating complexity, growth inflection points, or transformation.
The Trust Operating System™ is our proprietary methodology for organizational transformation. It addresses the root cause of dysfunction through three pillars: Shared Truth, Shared Language, and Shared Cadence. These create structural alignment that enables execution.
Unlike traditional consulting firms that deploy junior staff, our engagements are led exclusively by senior partners with decades of operational experience. We're implementation-focused. We stay engaged through execution, not just strategy.
We serve mid-market companies across manufacturing, financial services, professional services, healthcare, technology, and distribution. We have particular depth in sectors undergoing consolidation or requiring operational transformation.
A.L.L.I.S.O.N. is our proprietary intelligence platform that amplifies human judgement with intelligent orchestration. It accelerates analysis, ensures consistency across engagements, and helps surface patterns that drive better decisions.
We work with a select number of clients to ensure every engagement gets the attention it deserves. Let's explore whether we're the right fit.
