Culture isn’t a Perk, It’s a Strategy
A note for environmental consulting and engineering firms, and for any organization trying to grow in a market where talent is the product.
The environmental consulting and engineering industry is booming. The U.S. market grew at nearly 10 % annually over the past three years, expanding to more than 27 billion dollars in 2024. Global demand for environmental services is projected to grow steadily through the end of the decade, driven by regulatory complexity, infrastructure investment, and corporate sustainability commitments.
That growth sounds like good news. And it is, until you try to staff it.
What the Market Is Telling Us
The environmental consulting sector is facing a talent problem that is structural, not cyclical. An aging workforce is retiring faster than it can be replaced. The pipeline of new environmental scientists, engineers, and geologists is competitive. And the firms that rely on compensation alone to recruit and retain are discovering that it is an increasingly expensive and unreliable strategy.
The firms pulling ahead are doing something different. They are treating culture as a competitive asset, building organizations where people feel ownership, purpose, and genuine investment in the outcome. And the results show up in the numbers that matter most: retention rates, client satisfaction scores, and revenue growth.
Not convinced yet? Consultants surveyed by The Barton Partnership said the top reason they would consider leaving their current firm was higher pay. But close behind? Better company culture.
And here is what the data actually shows about what drives people to stay. According to Aon's 2025 Employee Sentiment Study, after compensation, the top factors influencing employee choices are:
A fun, engaging place to work (21 percent)
Strong value fit (20 percent)
Support for wellbeing (18 percent)
Flexible working (17 percent)
Nearly a third of that list has nothing to do with pay. It is about feeling like you belong somewhere that reflects who you are.
For environmental firms, this is especially true. The people drawn to this work are often mission-driven. They studied ecology, hydrology, environmental science, and engineering because they wanted to do something that mattered. When your firm's culture actually reflects that, when it walks the talk on purpose, you become a magnet for exactly the people you want.
Who's Getting It Right
AEI Consultants: Culture as an Executive Priority
AEI Consultants has been employee-owned since 2012. But what distinguishes them is not just the ESOP structure. AEI has a Chief Resilience Officer whose formal mandate includes guiding the firm's culture and organizational sustainability. That title, and the intentionality behind it, signals something important: at AEI, culture is not managed informally or delegated to HR. It is an executive-level responsibility with a named leader accountable for it.
Holly Neber, who formerly served as AEI's President and CEO and who now holds that role, brings more than 25 years of environmental consulting experience to it. She represents AEI in the industry, provides training on environmental due diligence and leadership, and serves on boards and committees that shape the profession. The Chief Resilience Officer role reflects a firm that understands culture and organizational health as long-term strategic investments, not short-term fixes.
I have watched Holly and AEI grow and flourish over the past decade. Seeing how intentionally they have built their culture, how clearly it shows up in the way their people talk about the firm and the work, and the growth they have experienced along the way has been an incredible thing to witness.
SWCA Environmental Consultants: 25 Years of Proof
SWCA Environmental Consultants has been employee-owned for more than 25 years. That longevity is not incidental. It reflects a sustained commitment to a model that aligns the interests of the firm with the interests of the people doing the work.
SWCA has received consistent recognition as a Best Place to Work across multiple markets. Their retention numbers reflect what happens when employees have genuine ownership in the outcome. And their growth reflects what happens when a firm is built on a foundation that clients and employees both trust.
If you are wondering whether the ownership culture at firms like SWCA and AEI is actually driving retention outcomes, the research says yes, decisively. According to the National Center for Employee Ownership, voluntary quit rates at ESOP companies are approximately one-third of the national average. A Rutgers University study found that employee-owned companies retained jobs at a four-to-one rate compared to non-employee-owned counterparts during the COVID-19 pandemic. Median job tenure at ESOP firms is 8.5 years, three years longer than at other companies. And nearly 80 percent of ESOP company leaders believe their ownership structure gives them a competitive edge in attracting and retaining top talent.
That is not a soft benefit. That is a structural advantage in a market where replacing an experienced environmental professional takes time and money that most firms underestimate.
Tetra Tech: Culture Built Around Excellence
Tetra Tech takes a different approach. They are not employee-owned in the ESOP sense, but they have built a culture around a specific and clearly articulated value: technical rigor. That clarity of identity attracts people who care deeply about doing excellent work and creates an environment where excellence is the norm rather than the exception.
The result is an 80 percent repeat client rate and consistent recognition as a top-ranked environmental and sustainability firm. Their clients stay because their people stay, and their people stay because the culture reinforces what drew them to the work in the first place.
Tetra Tech reported 4.2 billion dollars in revenue in 2024, up 15% year over year. That growth is not purely a function of market conditions. It is a function of a firm that has built something people want to be part of and clients want to come back to.
What Culture as a Strategy Actually Looks Like
Firms that treat culture as a strategy do not leave it to chance or assume it will develop on its own. They make deliberate choices about what they value, communicate those values clearly and consistently, and build systems that reinforce them over time.
That might mean an ownership structure like an ESOP, which aligns the financial interests of employees with the long-term health of the firm. It might mean a formal role dedicated to organizational resilience, as AEI has done with their Chief Resilience Officer. It might mean building a culture around a specific professional identity, as Tetra Tech has done with technical rigor.
What it does not look like is a set of values posted on a wall, a one-time offsite, or a benefits package assembled to match competitors. Those things are not culture. They are the surface of culture. The firms that are pulling ahead understand the difference.
The Business Case Is Not Complicated
Culture drives retention. Retention drives institutional knowledge. Institutional knowledge drives client relationships. Client relationships drive repeat work. Repeat work drives profitability and growth.
Every link in that chain is measurable. And the firms that have invested in culture as a strategy are outperforming those that have not on almost every dimension, from revenue growth to win rates to employee tenure to client satisfaction.
Think about it from a client's perspective. When you're selecting a firm for a complex environmental permitting project or a multi-year remediation effort, you're not just buying technical expertise. You're betting on a team. You're asking: Will these people care about my project the way I do? Will they still be here in Year 3?
The Bottom Line
The environmental consulting and engineering market will keep growing. Regulatory complexity, PFAS, water scarcity, climate adaptation demands, ESG reporting requirements; all of it is expanding the addressable work.
The question isn't whether there's enough work. The question is whether your firm will have the people to do it, and whether your clients will trust you to do it year after year.
Because the firms winning right now are not simply the ones with the best technical capabilities. They are the ones people actually want to work for. And those firms have figured out something that most leadership teams are still treating as secondary: culture is not a byproduct of a healthy business. It is a driver of one.
If your firm is navigating talent challenges or thinking through how to build a culture that becomes a competitive advantage, I would love to connect.
