From a Local Tax Advisor to a Regional Top Firm – Nearly 100 Years of History at a Glance
Which company can already look back on nearly 100 years of company history? Here are the key milestones of this long journey:
The Beginnings
The history of our firm dates back to 1932. Christoph Leidel laid the foundation by establishing himself as a „book auditor, trustee, tax and business consultant“ with a consulting office in Regen. In 1980, the firm was passed on to Peter Leidel. He continued the firm initially as a legal advisor with the support of trustees Stbvm Karl Zuber and StBin Agnes Fleischer, and from 1986 as a tax advisor.
Growth Years
Through continuous training and additional qualifications, the firm ensures that high-quality standards are met in all tax and business areas.
In 2022, the second location was opened in Deggendorf, and in 2024, a third location in Munich will be added.
The interdisciplinary firm is now led by partners Rudolf Stettmer (Tax Advisor), Jakob Eisenreich (Tax Advisor/Auditor), Marina Badelt (Attorney), and Karin Maurer (Tax Advisor).
Today
Starting in 2025, the firm will operate under the name REDONIS. This naming reflects the transformation and modernization that the firm has undergone in its nearly century-long history: moving away from a person-centered market presence towards an interdisciplinary firm, located between the REgen, the DONau, and the ISar.
Diverse Talents, Strong Individuals – United in a Cohesive Team
Our strength lies in diversity: Collaboration across disciplinary boundaries enables optimal coordination and creates synergies that meet every challenge effectively.
