Everything under one strong roof. WE are SONNTAG.
Constantly growing expertise, numerous experts and the development of further specialist areas have accompanied us at Sonntag & Partner Partnerschaftsgesellschaft mbB in recent years. We have continued to develop and founded the SONNTAG brand in 2021. This strong roof now unites all the experts, expertise and specialist areas and divisions we have acquired over the years.
The individual companies remained in their form and performance. Only the name changed from "Sonntag & Partner" to "SONNTAG" to emphasize the affiliation to the SONNTAG corporate network. Since then, the companies operate as SONNTAG Audit. Tax. Law; SONNTAG Family Office; SONNTAG Vermögensbetreuung; SONNTAG Audit and SONNTAG IT Solutions.
The transformation reflects the spirit and close collaboration within the company and further strengthens unity and external presence.
The topics of digitalization, specialization in the consulting fields, innovative solutions, the way (mobile) information flows and many other exciting areas play an important role in keeping up with the times.
We continue to meet the challenges of our clients with enthusiasm, support them proactively, and gladly accompany them into the future.
