We can look back on a long tradition with constant innovation. Since the 13th century our ancestors already dealt with Effort Venture.

• In 1270 the castles "Unter- und Ober-Sansch" were in the ownership of the brothers Conrad und Otto Straif 
• Land ownership from Grisons (canton of Switzerland) to St. Gallen
• In the middle of the 15th century, short-term expropriation of the possessions by Earl Friederich VII
• Reconqueror Peter Streiff von Diesbach born ~1480 is regarded as the progenitor of the Dynasty Streiff
• Significantly involved in the industrial revolution (16th century)
• Operation/ management of compulsory labours, production plants, mills
• High positions in the civil service (in the 15th and 16th century), 
• Between 1800 und 2000 several foundations were created (from culture to charitable purposes) 
• Up to the 19th century numerous scholarships have been established to obtain a good education.

Since hundreds of years it is part of the tradition of the Dynasty Streiff to offer holistic support (not simply in financial terms).
