htna Diversified Holdings, LLC (ADH) plays a key role within Ahtna, Inc. As the Alaska Native Regional Corporation (ANC), for the Ahtna region, Ahtna represents more than 2,300 shareholders and owns more than 1.5 million acres in the region. ADH is the largest holding company within Ahtna’s corporate family, which encompasses nine distinct subsidiaries.

But ADH is more than a collection of enterprises; it’s an economic force that accounts for more than half of Ahtna’s revenue. The company specializes in three core areas: construction (vertical and civil), environmental (investigation and remediation), and services (janitorial, O&M, and records management). Approximately 95percent of federal contracts with the Department of Defense (DOD) and other agencies.

These business lines are vital to the well-being of ADH’s stakeholders. “The money we make goes directly to providing opportunities for our shareholders and communities, whether that’s through jobs, programs, or direct support,” says Kevin Bergt, who was recently appointed president of ADH. “I’m very proud of the portfolio that we currently have and continue to build.”

Bergt is enthusiastic about his new role at ADH. His path to the presidency includes serving as director of operations, corporate counsel for Ahtna, and a prosecutor for the Anchorage District Attorney’s office.

“I wanted the challenge of taking an already successful organization to the next level and creating a global business, achieving scaled growth across multiple business lines,” he says.

Although ADH has embraced new leadership, it remains steadfast in its original mission: delivering excellence to clients, empowering tribal shareholders, and serving Alaska communities.

Through sustained growth, ADH has expanded to operate elevin offices in Alaska, Alabama, Hawaii, California, Colorado, Maryland, Washington, and, in 2025, Guam to better serve its growing Pacific Island workload. And with its expertise, resources, and capacity, ADH can effectively serve clients worldwide. The company has successfully delivered thousands of projects globally from Alaska’s Aleutian Islands to Africa and throughout the Pacific RIM.

ADH offers significant advantages to clients, ensuring continuity and efficiency in every project. It employs a common management and shared service model—covering accounting, business development, contracting, marketing, and procurement—to support its subsidiaries. This approach streamlines overhead spending and guarantees consistent branding, marketing, and operational practices throughout the organization.

To best meet project requirements, ADH selects the most suitable subsidiary based on client needs and NAICS classifications. ADH’s ANC 8(a) companies are eligible for direct awards at higher values—up to $100 million—without the formal justification approval process required for non-tribal contractors. “Government clients get the infrastructure they need delivered faster, and they generally get it at a better price point,” Bergt says. “And for us, there’s the certainty of an award. But it’s not a windfall; there’s full transparency in costs and margins are negotiated openly with the client.”

ADH is well-equipped to manage complex logistics, deploying staff to remote and challenging project sites—whether in the Aleutian Islands, Wake Island in the Pacific, or White Sands, New Mexico. “Ahtna has built a model of deploying site personnel in places that are not necessarily close to home,” Bergt says. “We will go wherever the opportunity arises; we’re flexible.”

ADH forms partnerships with industry leaders like Arcadis, Geosyntec, HPM Contracting, and Mortenson Construction, allowing it to participate confidently in large, complex, and highsecurity projects that require expertise and adaptability. Partnering with HPM, for example, enables ADH to participate in $100-million-plus projects that it might not pursue alone.

These collaborations not only add value for clients but also foster ADH’s growth and capabilities. “We’re able to learn from those partnerships because these are companies that have been in business for 100 years and can do very complex projects,” Bergt explains. “As we work with them and they provide training, they provide us with the experience of doing the projects side by side.”

ADH’s portfolio spans a range of successful construction and environmental projects. ADH companies bring the ability to perform construction in secured, sensitive facilities and locations. They possess staff with facility clearances and have experience with Sensitive Compartmented Information Facilities as well as Special Access Program Facilities. At Joint Base Elmendorf-Richardson, Ahtna is performing a highly complex Remedial Investigation/Feasibility Study at the former DRMO site which involves many classes of contaminants, a groundwater plume that extends offsite, and commingling contaminants plumes. Ahtna is performing a Human Health and Ecological Risk Assessment as part of the RI to evaluate impacts to receptors.

Additionally, ADH delivers major service contracts in records management, janitorial, and O&M work for federal clients, such as maintaining over a million square feet at NOAA’s Western Regional Center in Seattle. At Eielson Air Force Base in Alaska, the company is designing and constructing infrastructure for a colloidal activated carbon injection system to contain the on-site per- and polyfluoroalkyl substances contamination in groundwater.

But none of this would be possible without the dedication and assiduous efforts of ADH’s 400-plus “wonderful” employees, according to Bergt. He emphasizes: “You’re only as good as your people. We owe a lot to the hard work of our employees and talented individuals that make up our company.”

Their hard work has been recognized through eleven local, regional, and national awards in the past five years. ADH honors include NAWIC and SAME Seattle Post Project Excellence awards for the EPA Laboratory Modernization Project (Corvallis, Oregon), Commander Excellence Award for work at Fort Belvoir (Virginia), SAME Small Business of the Year award, and multiple Associated General Contractors of Alaska Project Excellence and Safety awards.

Going forward, ADH will continue to promote sustainable growth while preserving its unique culture and high standards. The company will further refine its operating models, processes and systems to ensure its differentiator remains excellent client service and satisfaction.

ADH is known as a company of integrity, for quality client experiences, and for its stewardship of profits that support shareholder programs, jobs, and village quality of life. “We are a complex, sophisticated organization that delivers quality performance safely and on par with any other company,” Bergt emphasizes. “We are known not just for our contributions to our shareholders but also as a solid and ethical company.”
