RSM incorporates the Seville-based Aúna
RSM, the global network of audit, legal, tax, consulting, and corporate finance services, has taken a significant step in its strategic growth plan with the integration of Aúna, a highly regarded Seville-based audit firm. This move strengthens RSM’s position in one of Spain’s key business hubs and doubles its professional team in the region.
Founded by Álvaro Fernández Moreno and Gabriel Guardiola Tassara, Aúna has earned a reputation for its dynamic team and deep expertise in audit, financial consulting, and analytical reporting. The firm has built a solid client base across industries such as construction and engineering, industrial manufacturing, services, distribution, and agribusiness.
Álvaro Fernández, a graduate in Business Administration and Law with a Master’s in Auditing and Executive Development from Loyola Leadership School, spent nearly a decade at Deloitte before co-founding Aúna. Gabriel Guardiola, also a Business Administration graduate, brought over 11 years of experience from EY to the firm. Together, they lead a team of specialists well-versed in national and international audit projects, financial due diligence, forensic economic reports, and government subsidy audits.
With this integration, RSM significantly expands its Seville operations, now employing 50 professionals across its legal, tax, and audit practices in Andalusia.
“The addition of audit services through Aúna is a key milestone in consolidating our Seville office and advancing our growth strategy in Spain,” said Mario Cepero, RSM’s Head of Audit. “Álvaro and Gabriel bring not only deep technical expertise but also a strong cultural fit that aligns perfectly with RSM’s values.”
The founders of Aúna echoed this sentiment: “RSM’s philosophy is closely aligned with the principles we set out with when we launched Aúna in 2017. In an increasingly complex audit landscape, joining a multidisciplinary global firm like RSM gives us the ability to broaden our reach and reinforce our commitment to delivering high-quality, tech-enabled service to a growing base of global clients.”
