Aprio Acquires Philadelphia-Based Isdaner & Company, Expanding Advisory Power to Business Leaders in the Northeast

Aprio, the 20th largest business advisory and accounting firm in the United States, has announced its acquisition of Isdaner & Company, a full-service accounting and advisory firm based in Bala Cynwyd, Pennsylvania. The transaction, which is effective as of June 1, 2026, aims to enhance Aprio's footprint in the greater Philadelphia market. While the financial terms of the deal remain undisclosed, the acquisition is expected to consolidate a range of accounting, advisory, audit, and tax services under one umbrella, benefiting local businesses and families.

Isdaner & Company has established a strong reputation over nearly six decades, serving closely held businesses, high-net-worth individuals, and a variety of organizations throughout the Delaware Valley. The firm employs over 70 professionals who provide a comprehensive suite of services, including accounting, auditing, tax services, trust and estate services, business consulting, and litigation support. The addition of Isdaner & Company not only broadens Aprio's service offerings but also strengthens its local expertise, particularly in sectors such as real estate, manufacturing, and nonprofit organizations.

The strategic rationale behind this acquisition is clear: as client needs become increasingly complex, firms must evolve to meet those demands. Aprio's CEO, Richard Kopelman, emphasized the importance of building trusted relationships with clients and positioning the firm as a growth partner throughout various stages of their business journeys. By integrating Isdaner & Company's established practices and community ties, Aprio aims to deliver enhanced value and a more comprehensive service model to its clients in the region.

This acquisition is part of a broader trend in the accounting and advisory sector, where firms are consolidating to expand their capabilities and geographic reach. Aprio has been actively pursuing growth through similar transactions, including the recent acquisitions of Price Kong in Phoenix and CAVU Advisors in Columbia, Maryland. These strategic moves reflect a commitment to building a robust platform that can address the diverse needs of clients, particularly in a post-pandemic economy where businesses are seeking more integrated solutions.

Looking ahead, the acquisition of Isdaner & Company positions Aprio to capitalize on growth opportunities in the Northeast and beyond. As the demand for comprehensive advisory services continues to rise, firms that can effectively combine resources and expertise will likely gain a competitive edge. The integration of Isdaner & Company into Aprio's operations not only solidifies its presence in Philadelphia but also sets the stage for future growth and innovation in the accounting and advisory landscape.
