The Owner Mandate

For owners who run a company and private wealth. In twelve weeks we set up three things: the secretariat of your management, your private secretariat with a personal concierge, and an orderly overview of assets and real estate. Dr. Quintana Díaz accompanies every mandate personally.

We built it for ourselves first. Since September 2026 Alfred has run the secretariat of Dr. Quintana Díaz.

We take on few mandates per quarter, most of them on referral.

Arrange a conversation

The asset overview is organisational preparatory work. Tax, legal and investment advice is provided by licensed professionals.

Talks

Dr. Quintana Díaz gives talks for entrepreneurs, banks and family offices, among others. His focus is philosophical questions on the themes of our time.
