LEA firms operate with combined annual revenue of more than $2.7 billion.


The combined strength of LEA member accounting and advisory firms creates a global powerhouse of professional service organizations. Members can leverage the alliance for all their accounting and advisory needs, ranging from simple audit assistance to advice on complex global acquisitions. LEA’s wide range of expertise crosses many services and industries. The alliance provides members with the size and scope of a large multinational company while offering clients the continuity, consistency and quality services of a local firm.


Member firms go through a rigorous review before being accepted into the Leading Edge Alliance to ensure they are successful, quality firms that have enduring client relationships and long-standing ties to the communities they serve.


Unlike Big 4 firms, LEA Global firms identify closely with their clients because they, too, are business owners seeking to grow their companies. They create innovative solutions to their clients’ challenges and proactively counsel them on opportunities.
