About us

Our company history

Our origins resemble the history of accounting and tax consultancy over the past 65 years in Spain. About 50 years ago, my father, Dionisio F. Sánchez Lorenzo, a trade teacher, laid the foundation for what is today DEVENTER CONSULTING.

In those early years, the offered services were limited to basic accounting and the payment of tax obligations. There were years when accounting had little relevance, and taxation was reduced to the payment of what the famous “Juntas de Evaluación Global” allocated to one.



Fortunately, things in Spain have changed a lot. The arrival of democracy in Spain meant for the first time that we had a tax system that was comparable with our environment, and accounting was gaining prominence, just as accountants were gaining prominence.

Our office has also evolved over these years, from the classic tax consulting office to the “local expert” for tech start-ups and the implementation of cloud-based software, which greatly simplifies and optimizes the information exchange with our customers.

With Denis Gloger as director and representing the third generation of our family, the firm has grown significantly in the last 10 years, offering services for international clients from all over the world.
