Sonntag Family Office
Sonntag Family Office was established in 2001 as a subsidiary of a regional law firm. Andreas Kerpf leads the firm as Managing Director alongside Stefan Grießer and Eva-Maria Erhard. The wealth originates from the founders’ legal practice and client families seeking structured oversight. The firm delivers asset analysis, structuring, and implementation across real estate and liquid holdings. It coordinates service providers for mixed-use properties in Augsburg and commercial portfolios in Wolfsburg, Kassel, and Duisburg. Geographic focus remains Germany with network support for cross-border matters. No fund commitments or named external co-investors appear in public records. Team size and AUM remain undisclosed. The firm lists philanthropic ties to the PATRIZIA Foundation and Tabaluga Kinderstiftung. No operational events from the last 24 months are recorded. The structure originated as a law-firm spin-off, embedding legal advisory directly into investment governance and succession mandates.
