Guidehouse’s Twin Engines: New CFO and CXO to Pilot a $1.5B AI Future

MCLEAN, Va. – July 22, 2026 – In a move that signals a calculated and aggressive push into the next era of professional services, Guidehouse has appointed two key executives to steer its dual ambitions of financial fortitude and technological dominance. The firm named Kelly Hernandez, a seasoned financial leader, as its new Chief Financial Officer (CFO), while simultaneously creating the role of Chief Transformation Officer (CXO) for Stuart Brown. These are not parallel hires but a unified statement of intent, strategically coupling the fiscal governance required for sustainable growth with the visionary leadership needed to operationalize a colossal $1.5 billion investment in artificial intelligence.

Fortifying the Financial Engine for Aggressive Growth

The appointment of Kelly Hernandez as CFO comes at a pivotal moment for Guidehouse. Since its formation in 2018, the firm has been on a remarkable growth trajectory, swelling from a $600 million operation to a global powerhouse with revenues exceeding $3 billion and a workforce of approximately 18,000 professionals. This expansion was fueled by a series of high-profile acquisitions, including Navigant Consulting and Grant Thornton's public sector arm, and culminated in a $5.3 billion acquisition by Bain Capital in late 2023. Managing the financial architecture of such a rapidly scaled enterprise requires a specific and proven skill set.

Hernandez brings precisely that. Her recent experience as CFO at Clark Construction Group and, critically, her senior leadership tenure at government contracting giant Leidos, provides her with a deep understanding of the complex financial ecosystems in which Guidehouse operates. At Leidos, she was instrumental in supporting strategic growth and financial performance, experience that will be directly applicable to her new role.

"Kelly brings a unique combination of financial expertise, operational leadership, and strategic perspective," said Scott McIntyre, CEO of Guidehouse. "Her experience leading organizations through growth and transformation will be invaluable as we continue investing in our business, expanding our capabilities, and creating long-term value for our clients and stakeholders."

For Hernandez, the task is clear: to institutionalize the financial discipline needed to support the firm’s next phase of investment and innovation. "I'm excited to join the firm at a time of continued growth and investment," Hernandez stated, emphasizing her focus on strengthening the "financial foundation and operational discipline that will support the next phase of Guidehouse's success."

The New Architect of Transformation

While Hernandez fortifies the financial foundation, Stuart Brown has been tasked with building the future upon it. The creation of the Chief Transformation Officer role is perhaps the most telling aspect of Guidehouse's strategy. It represents a fundamental shift in the firm’s operating model—moving, as the company noted, from seeing technology as an enablement tool to embracing it as a primary driver of enterprise value. This is the new reality in a market where competitors like Accenture and Booz Allen Hamilton are all racing to define the AI-powered consultancy.

Brown, who joined Guidehouse in January 2025 after a long career in technology leadership at Accenture, is no stranger to large-scale digital initiatives. In his 18 months leading the firm's digital business, he has been laying the groundwork for this moment. His promotion to CXO is a mandate to unify and accelerate the firm’s AI strategy across its entire operation, from internal processes to client-facing service delivery.

"Stu has been instrumental in shaping our technology strategy and positioning Guidehouse for the future," said John Saad, President of Guidehouse. "This role will create a more unified direction across the firm as clients across highly regulated industries move from experimentation to measurable results."

This move gives a formal structure to the firm's multi-year, $1.5 billion AI investment. Brown's primary challenge will be to translate that massive capital commitment into tangible, scalable, and—crucially for Guidehouse's clientele—secure solutions.

From Theory to Practice: AI in Highly Regulated Worlds

For Guidehouse, which built its reputation serving complex government and commercial sectors like national security, healthcare, and financial services, the AI revolution is not just about innovation; it's about trust. This is where the firm sees its competitive advantage. As Brown himself noted, success in these industries requires more than just novel algorithms.

"Everyone is racing to unlock AI's potential, but in the industries we serve, success requires more than innovation alone," said Brown. "It requires the ability to deliver outcomes in complex environments while keeping systems secure, governed, and trusted." This philosophy is already being put into practice. In healthcare, the firm is leveraging AI and automation to help health systems achieve a "touchless" revenue cycle, with KLAS Research reports indicating that 100% of its end-to-end revenue cycle outsourcing clients would buy from the firm again.

In the government sector, a 2025 survey conducted by Guidehouse and the Association of Government Accountants (AGA) revealed that while finance leaders are optimistic about AI, they are cautiously pragmatic, prioritizing governance and workforce readiness. By appointing a CXO focused on governed transformation, Guidehouse is directly addressing this core client concern. Similarly, the firm recently launched a financial management AI solution powered by Databricks, designed to enhance audit speed and precision for its financial services clients. These are not abstract promises of transformation but concrete applications designed for mission-critical functions.

By pairing a battle-tested CFO with a dedicated architect for its AI-driven future, Guidehouse is not merely announcing new hires. It is revealing a sophisticated, integrated strategy designed to outmaneuver complexity and solidify its position as a leader in the next generation of professional services.
