Inclusive Culture
GHA: Inclusive Culture
At GHA, our inclusive culture is the foundation of who we are. It represents our commitment to fostering a workplace where everyone feels valued, respected, and empowered to succeed. By combining our core values and initiatives, we aim to create an environment where individuals can thrive both personally and professionally.
WHAT DEFINES OUR CULTURE
Our culture is built on collaboration, mutual respect, and a shared vision for success. We believe in creating a workplace where people feel empowered to bring their authentic selves to work every day.
Through initiatives like team-building events, employee-led committees, and professional development programs, we encourage growth and connection at every level. Events such as the GHA Summer Picnic, Pancake Breakfast, and annual Wiffle Ball Tournament are just a few ways we celebrate our team and create lasting bonds. By fostering an environment that encourages open communication, innovation, and support, we aim to build a community where every individual feels a sense of belonging.


“Our employee handbook has been rewritten to incorporate more inclusive language that represents our current culture and creates a welcoming environment for new hires. We are dedicated to fostering an inclusive workplace where every individual feels respected and included.”
-Anika Moore, MAIO, Chief People Officer
HOW WE FOSTER AN INCLUSIVE CULTURE

WOMEN’S EMPLOYEE RESOURCE GROUP (WERG)
The Women’s ERG is a vital part of GHA’s inclusive culture, focused on empowering women-identifying employees through networking, mentorship, and educational initiatives. This group creates a platform where women can share experiences, support one another, and foster leadership skills.
The ERG hosts events and workshops that promote professional development and personal growth, while also advocating for equitable opportunities across the company. By amplifying voices and providing meaningful resources, the Women’s ERG is helping to cultivate a workplace where everyone has the opportunity to succeed.
GIVING BACK TO OUR COMMUNITY
At GHA, our commitment to inclusion extends beyond our workplace and into the communities we serve. Through philanthropic initiatives and volunteer efforts, we aim to make a positive impact and contribute to the well-being of those around us.
Each year, our team participates in programs like Toys for Tots, Adopt-A-Highway programs in Lake County and Kansas, and contributes to organizations like St. Jude Children’s Research Hospital and the Northern Illinois Food Bank. We also prioritize educational outreach by partnering with schools and organizations to inspire the next generation of engineers and leaders. Whether through career day programs, mentorship programs, or career fair participation, we aim to build a more diverse and inclusive future for our industry.
By actively engaging with our communities, we ensure that the values of inclusion and equity are reflected in all aspects of our work—not just within our walls.

“We strive to create an inclusive environment where everyone’s voices are heard and valued,” says Wadee Rafati, a key member of the ICC committee. “We are dedicated to driving meaningful change and building a workplace that celebrates diversity and promotes equity.”

Our Core Values:
Ownership
At GHA, ownership means taking personal responsibility for the firm’s success, aligning our goals and outcomes with a shared vision. This value inspires a culture where every team member feels invested and proud of the work we do together. We demonstrate ownership by approaching our work with urgency, focus, and a commitment to quality in every project we deliver.

Integrity
Integrity is at the core of everything we do at GHA. We are committed to diversity, equity, and inclusion (DEI). Our DEI committee, which was established in 2020, cultivates partnerships to advance DEI within our firm and our community. Our DEI initiative is enriched through our long-standing partnership with Cristo Rey St. Martin College Prep. By collaborating on their “Corporate Work Study Program,” we’ve been providing educational opportunities and career pathways for youth since 2004.

Passion
At GHA, our passion for community involvement is a vital part of our identity. We deeply value our role in positively impacting the places we inhabit and work. This commitment to making a difference is evident in our active engagement with environmental conservation efforts. Our longstanding partnerships, such as that with Friends of the Chicago River, enable us to participate directly in initiatives aimed at creating cleaner and more sustainable waterways for the enjoyment of future generations.

Initiative
Recognizing opportunities and anticipating challenges is central to how we work. Initiative means taking independent action to solve problems and improve outcomes. Empowered by ownership in the company, our team embraces creative thinking and actively seeks out better ways to deliver results. From identifying potential issues early to implementing innovative ideas, initiative drives meaningful progress in everything we do.

Accountability
Accountability means holding ourselves and each other to the highest standards. It’s about clear communication, honest feedback, and owning our actions—both successes and setbacks. This approach builds trust and dependability across our teams, fostering an environment where growth and collaboration thrive. It’s the foundation that supports everything we do. Whether setting clear goals, addressing challenges directly, or learning from mistakes, accountability ensures we’re always moving forward together.


ESOP Advisory Council
ESOP ADVISORY COUNCIL

The GHA Employee Stock Ownership Plan (ESOP) Advisory Council is not just a committee, but a pivotal component in shaping a robust culture of ownership, engagement, and professional advancement among GHA’s employee-owners. Acting as a key element within GHA’s ownership structure, the council plays an essential role in both sustaining and evolving a shared vision for the future trajectory of the company.
COUNCIL COMPOSITION
Our council is made up of ten diverse representatives, each hailing from a different division within GHA. This structure ensures a broad spectrum of voices are heard, reflecting the company’s unified commitment to its employee-owners.
ROLES AND RESPONSIBILITIES
Liaison to Leadership: The council ensures the interests and perspectives of GHA’s employee-owners are effectively communicated to the Board of Directors.
Onboarding: The council works diligently to integrate new members swiftly, ensuring effective and efficient operations moving forward.
Conference Participation: Council members are expected to attend at least one ESOP Association conference during their term, ensuring a continuous influx of fresh perspectives and best practices.
Educational Programs: Continuously updating and providing ESOP-specific educational materials for new and existing employee-owners.
Event Coordination: Creating and managing a comprehensive annual calendar of events that align with GHA’s core values and ESOP objectives.


OBJECTIVES AND GOALS
Initially established with a focus on communication, culture, and employee engagement, the council has continually evolved its objectives to adapt to GHA’s changing needs.
Core Values and Mission: In alignment with GHA’s foundational beliefs and commitments, the council focuses on transparent communication, comprehensive education, and the coordination of special events.

Ongoing Communication: Improving communication and engagement throughout our offices.
FUTURE VISION
The ESOP Advisory Council plays a critical role in enhancing the integrity of GHA’s ownership model by faithfully representing the diverse interests of all employee-owners. This representation serves as a fundamental aspect of the council’s role, granting it the authority to voice the interests of each division within the company. The council’s goals for GHA’s future extend beyond short-term achievements but include a shared long-term vision. This vision is geared toward a workspace where new ideas are valued, and originality is encouraged.
Through these efforts, the council seeks to go beyond its function as a liaison between employee-owners and the leadership of GHA, aiming to be a proactive force in advancing the company’s journey toward innovation and shared success.
Employee Owned
GHA is an Employee Stock Ownership Plan (ESOP) Company

In 2018, GHA transitioned to an ESOP organization. This signifies that every member of GHA’s staff possesses an owner’s stake in enhancing our services and the value they deliver to our clients. Beyond the financial benefits for all GHA Co-Owners, we deeply believe in the contributions each one of us can make through our experience, insight, and dedication. This belief drives a variety of employee opportunities, always anchored in the understanding that we, the Co-Owners, possess a distinctive voice that demands recognition.

WHAT IS AN ESOP?
At Gewalt Hamilton Associates, our team members are more than just employees; they are vested stakeholders in the company through our Employee Stock Ownership Plan (ESOP). An ESOP is a specialized retirement plan that operates through a trust, a distinct legal entity that acquires, holds, and manages company stock for the benefit of its participants. This unique structure allows GHA co-owners to receive company shares as a portion of their compensation, providing them with a vested interest in the company.
HOW DOES AN ESOP WORK?
Much like a 401(k) plan, an ESOP provides a framework for long-term retirement savings. However, there are key differences. In our ESOP, employees are not required to contribute financially to acquire company shares. Instead, Gewalt Hamilton Associates takes on the responsibility of making all contributions. This reflects our dedication to investing in the people who make our success possible.
The value of each ESOP account is directly linked to the stock price of Gewalt Hamilton Associates, rather than external market securities. This ensures that as the company continues to grow and thrive, so does the financial well-being of our team members. To maintain transparency and integrity, the value of our company stock is assessed annually by an independent third-party appraiser. Any increase in the stock value is then equitably redistributed to the ESOP beneficiaries—our valued owners-employees.
By implementing an ESOP, our goal is to nurture a culture where excellence and innovation are the norm, as every team member has a direct stake in the company’s overall performance and success.


BENEFITS OF PARTICIPATING IN AN ESOP
Participating in an ESOP offers numerous advantages that go beyond traditional retirement plans:
Alignment of Interests: With a stake in the company, team members are naturally motivated to contribute to its success, thereby creating a cohesive and focused work environment.
Financial Security: The ESOP provides an additional layer of financial stability for retirement, supplementing other retirement savings plans you may have.
Tax Benefits: ESOPs come with certain tax advantages, both for the company and for the employee beneficiaries, making it a financially prudent choice for long-term planning.
Shared Success: As the company grows, the value of the ESOP shares also increases, allowing co-owners to directly benefit from the company’s success.
ESOP ADVISORY COUNCIL
The GHA Employee Stock Ownership Plan (ESOP) Advisory Council is not just a committee, but a pivotal component in shaping a robust culture of ownership, engagement, and professional advancement among GHA’s employee-owners. Acting as a key element within GHA’s ownership structure, the council plays an essential role in both sustaining and evolving a shared vision for the future trajectory of the company.
At GHA, each division is represented on the council, ensuring an approach where every opportunity is explored and every concern is addressed. We take pride in our inclusive culture, and as a testament to this, all GHA Co-Owners are invited to serve on the ESOP Advisory Council for a term. Those who have taken up this opportunity unanimously agree that it offers a unique platform to actively shape GHA’s future.
Our culture at GHA is deeply rooted in a shared journey toward the future, with each of us as Co-Owners playing a pivotal role. Throughout the year, we have numerous celebrations that underscore this collective spirit. The Annual Stock Reveal is a moment we all eagerly await each year. The dedicated members of the ESOP Advisory Council pour their energy into making this event memorable, ensuring not just insightful discussions but also great food and team-building fun.
COMPANY CULTURE
The ESOP model inherently encourages a culture of collective responsibility and mutual respect. Team members are not just employees but co-owners who have a vested interest in the quality of work and solutions we provide to our clients. This sense of ownership creates a work environment where integrity and excellence are not just expected but are a natural outcome of our company culture.
By integrating an ESOP into our benefits package, Gewalt Hamilton Associates aims to create a workplace where everyone’s contributions are recognized and rewarded, and where each team member benefits directly from our collective success.
