Juneteenth is observed annually on June 19 to commemorate the end of slavery in the United States. The 2026 Juneteenth theme, “Juneteenth Brings Balance to America’s Celebration of Freedom,” reminds us that our nation’s story is strongest when all voices, experiences, and contributions are recognized as part of our shared history.

As a majority African American-owned civil engineering firm, IEI recognizes that progress is built through opportunity, inclusion, and investment in communities. The work we do every day helping plan, design, and improve infrastructure contributes to creating places where people can thrive.

On Juneteenth, we honor the resilience, achievements, and lasting contributions of African Americans, reflect on the progress that has been made, acknowledge the work that remains, and reaffirm our commitment to advancing equity, expanding opportunity, and leading with purpose in the communities we serve.

Every June, Pride Month celebrates the LGBTQIA+ community and honors the ongoing pursuit of equality, inclusion, and belonging.

This year’s theme, “For All of Us,” inspired by the words of Marsha P. Johnson, “There is no pride for some of us without liberation for all of us,” highlights the importance of unity and collective progress across the LGBTQIA+ community.

At IEI, we recognize and celebrate the voices, experiences, and contributions of LGBTQIA+ individuals and reaffirm our commitment to fostering a workplace where everyone feels respected, supported, and empowered to succeed.

Join us this month as we celebrate Pride by embracing authenticity, promoting equity, and standing in solidarity for all of us.

When I joined IEI 20 years ago, we were much smaller, but there was already a clear sense of purpose in our work. It wasn’t just about winning projects or growth; it was about doing meaningful work, doing it well, and building something that would last.

As I step into the role of CEO, that purpose remains unchanged. What has evolved is the scale of what IEI can deliver with and for our clients and partners, and the pace at which our industry and communities are changing.

Looking ahead, the next chapter of IEI will require us to think differently, expand our capabilities, and continue to grow as an organization. The strengths that brought us here provide a strong foundation, but part of our firm culture has always been a commitment to continuous improvement and learning, never standing still, and always evolving to better meet the needs of our clients, partners, and communities. That responsibility includes continuing to challenge ourselves, strengthen our capabilities, and adapt as the needs of our industry and clients evolve.

I’ve had the opportunity to grow alongside this company, learning from our founder, Michael Sutton, PE, working with talented colleagues, and partnering with clients who trust us with complex challenges. Those experiences shape how I approach this role: with respect for what’s been built and a clear sense of responsibility for moving it forward.

Michael’s vision created the foundation for who we are today, and I’m grateful we’ll continue to benefit from his guidance as Chairman of the Board. I’m also confident in the strength of our team across all ten IEI offices and the thoughtfulness and accountability they bring to their work every day.

We don’t take for granted the role we play in the communities we serve. Much of our work happens out of sight, but it shapes how people live, move, and connect. It’s a responsibility we approach with care, and one we’ll continue to take seriously as we grow.

To our clients and partners, thank you for the relationships you’ve built with us over the years. And to our employees, thank you for the commitment you bring to your work every day. I’m looking forward to what we’ll continue to accomplish together.

Sincerely,

Kashif Khan, PE

Chief Executive Officer

IEI is pleased to announce the promotion of Sonya Jordan, SPHR, Jeana Majeske, CPSM, and Dr. Kia A. Sutton, CPSM to Vice President roles within the firm. At IEI, our strength is built on the leadership and dedication of our people. The vision, experience, and strategic leadership that Sonya, Jeana, and Kia bring to IEI contribute meaningfully to our operations, sustained growth, and the value we deliver to our clients.

Sonya Jordan, SPHR, Vice President of Human Resources, has cultivated a high-performing workplace grounded in accountability and respect. She has strengthened talent acquisition, enhanced professional development, and reinforced a culture where employees are empowered to do their best work and build meaningful careers. As Vice President of Human Resources, Sonya will continue advancing initiatives that strengthen our teams, elevate leadership capability, and position IEI as a firm where talented professionals are inspired to contribute, while supporting the consistent delivery of engineering excellence for our clients.

 

Jeana Majeske, CPSM, Vice President of Marketing, has elevated how we communicate our capabilities and connect with the communities and clients we serve. Her leadership has sharpened our strategic messaging, strengthened pursuit efforts through technical rigor and responsiveness, and reinforced collaboration across teams to align strategy with client needs. As Vice President of Marketing, Jeana will continue guiding market strategy and brand positioning efforts that enhance clarity, competitiveness, and long-term partnerships to deepen client trust, broaden our presence, and drive sustainable growth.

 

Dr. Kia A. Sutton, CPSM, Vice President of Business Development, has played a key role in shaping IEI’s strategic growth across established and emerging markets by aligning long-term vision with disciplined business development execution.

This year’s Black History Month theme, A Century of Black History Commemorations, marks 100 years since Dr. Carter G. Woodson launched the first national effort to preserve and share Black history. What began in 1926 as Negro History Week sparked a movement rooted in the belief that history must be documented, protected, and taught.

A century later, that mission remains vital. Black history is American history and that its stories deserve to be seen, heard, and remembered.

As a majority African American–owned civil engineering firm, IEI’s success reflects the determination of the educators, advocates, engineers, and leaders who expanded opportunity in industries where representation was once limited. That legacy guides our work every day. We are driven to deliver equitable, lasting solutions that strengthen neighborhoods and shape communities where everyone can succeed.

This Black History Month, we celebrate a century of honoring Black voices and achievements and recommit to advancing opportunity, representation, and impact within our industry. By learning from the past and investing in the next generation of engineers and leaders, we continue the work of building a future defined by possibility.
