RKL, a leading advisory firm with an office in Exton, ranked first in Pennsylvania and 58th nationwide in the latest roundup of the 100 largest accounting firms from industry publication Accounting Today.

RKL’s 2026 national ranking is based on 2025’s revenue of $151.54 million. The firm also ranked ninth among the top firms in the Mid-Atlantic.

“This recognition is a direct reflection of the exceptional professionals at RKL,” said RKL CEO Ed Monborne. “Our team’s collaborative spirit, deep expertise, and genuine care for our clients and communities are what set us apart.”

In 2025, RKL continued to set new standards for excellence, grounded in a relationship-centered approach that distinguishes the firm in the advisory space. As the One Big Beautiful Bill Act reshaped the tax landscape, RKL delivered timely, practical guidance through its “What’s Next” webinar series, a dedicated OBBBA Resource Center, and speaking engagements across the region, equipping thousands of decision-makers with the clarity and confidence to navigate change.

RKL’s commitment to client service was reflected in the firm’s September 2025 Net Promoter Score of 82.8 percent, sustaining its “world-class” standard and reinforcing the strength of its client relationships.

That same world-class experience extends beyond client service and into the firm’s culture. In 2025, RKL ranked eighth among large employers in the “Best Places to Work in PA,” was named the Cumberland Valley Business Alliance’s “Employer of the Year,” and earned recognition from the PA Chamber as a top employer for internships — affirming RKL’s continued investment in its people and the communities it serves.
