About us

Private Bankers since 1986

SDM actively manages and preserves the wealth of Belgian and international families. It is in this capacity, that many high net worth individuals and corporates trust SDM across generations. 

As a family-owned company, we have many years of experience managing family wealth, and providing asset management services.

At SDM, we strive towards long-term relationships and commitments that transgress generations and which are built on confidentiality, discretion and expertise.

Mission and values

Our mission is to be the trusted partner for individuals, families and businesses on their journey to preserve their wealth for future generations. The long-term mindset, the absence of conflict of interest and the personalised investment approach set SDM apart.

Transmission from generation to generation

As a family business, we understand the financial complexities that come with preserving wealth. Our business model focuses on the long-term horizon and is aligned with our clients’ goal of transferring their wealth to the next generation. Our long-term relationships are built on confidentiality and trust that transgress generations. We serve as your trusted partner on your families’ investment journey.


As an independent financial structure, we are committed to safeguarding and growing the wealth of our clients in a sustainable and responsible manner. We distinguish ourselves by using a transparent investment method. This method is mainly based on 'direct lines' and on a clear and accurate cost structure. The main aim of this process is to avoid conflicts of interest, which all too often arise between bank and client.


Each family is unique. Our experienced team is fully dedicated to understand your financial objectives and design customised solutions for your financial needs. At SDM's discretionary asset management division, which constitutes the majority of its activities, we build tailor-made investment portfolios to better serve our clients' unique financial goals. Our experienced investment team creates independent in-house research based on dutifully selected sources.

Tailor-made investment portfolios based on independent in-house research, sets SDM apart.


Continuity is the key to a successful relationship. The senior members of SDM have considerable experience and hold recognised professional qualifications. The majority of our staff have been employed within our organisation for many years and we are justifiably proud of their immense achievements. This continuity has enabled them to forge a close rapport with their clients.

Your attentive managers will be well versed in both your business and private affairs through close, regular contact. You will find that they are easily accessible and are more than pleased to provide information or guidance on any aspect of your concerns. We have found that the transparant nature of SDM, combined with the tailored investment services has been greatly valued by our clients.
