MacKay Sposito Becomes MacKay: A New Chapter in Our Growth

Apr 30, 2026 in News

Today marks an important moment for our company.

MacKay Sposito is becoming MacKay.

This change reflects a strategic step forward as we continue to grow, expand our capabilities, broaden the services we offer, and strengthen our presence across the country. As our firm has evolved, it became clear that our name should more clearly represent who we are today and where we’re going.

While our name is changing, the foundation of our company remains the same.

Our legal entity continues as MacKay Sposito, LLC, and there are no changes to contracts, services, or how we do business. Our clients will continue working with the same teams and relying on the same relationships they’ve built with us over time.


A Clearer Expression of Who We Are

The transition to MacKay represents more than a name change. It reflects how our company is growing and the direction we’re headed.

We are expanding across the country, growing our range of services, and entering new markets. At the same time, we are bringing together talented teams and diverse expertise through both organic growth and strategic acquisitions.

This approach is intentional.

We believe growth should build on what already exists. By bringing together strong teams, distinct histories, and shared values, we are creating something even more capable and resilient. The result is a company shaped by a collective of experience, perspectives, and relationships.


Growing with Purpose

Over the past several years, MacKay has continued to build momentum, expanding our geographic footprint and strengthening our capabilities to better serve our clients and communities.

Today, we serve clients across the United States, delivering multidisciplinary infrastructure and environmental solutions that support critical systems and improve the places where we live and work.

As CEO Derrick Smith shared:

“We’re entering a new phase as a company. Our growth has been intentional, expanding our reach, strengthening our capabilities, and creating new opportunities for our employees and clients. Becoming MacKay reflects where we’re going and positions us to compete and lead on a broader stage.”


What’s Not Changing

While our name is becoming simpler, our core remains the same.

Our values, Honesty, Dedication, and Relationships, continue to guide how we work, how we serve our clients, and how we support one another.

Our commitment to delivering high-quality work and building lasting partnerships remains unchanged.


Honoring Our Legacy

As we look ahead, we are also taking time to recognize the history that brought us here.

We are proud to honor the contributions of co-founder Richard Sposito through the creation of the Dick Sposito Internship Program, supporting future generations of professionals entering our industry.

We are also introducing “Legacy Days” to celebrate the history, partnerships, and shared experiences that have shaped our company and the firms that have joined us along the way.


Looking Ahead

You will begin to see the MacKay name reflected across our offices, communications, and materials, with updates rolling out in phases.

This next chapter is about building on a strong foundation while continuing to grow with purpose.

We are proud of where we’ve come from and excited about where we’re going.
