DAAN REEKERS
CEO Adelaer Group
After completing his HEO (Higher Professional Education) degree, Daan Reekers completed several postgraduate programs in financial planning and real estate. He has worked in the real estate sector for over sixteen years, twelve of which as an independent entrepreneur.
Besides an independently established advisory practice specializing in residential and commercial property financing, Daan also has experience as an independent developer. After the financial crisis, Daan scaled back these activities to focus solely on Real Estate Finance and Equity Partnership. He is an entrepreneur who, like his clients, knows the ropes.
Over a decade ago, Daan established the first contacts with our foreign investors, including investment banks, banks, and institutional and pension funds. Today, these long-standing relationships foster trust and decisiveness between Adelaer and its partners.

DENNIS VAN DER DONK
CFO Adelaer Group
Dennis has over 27 years of experience in financial services. He started in banking in 1995 as a financial advisor and transitioned to self-employment in 2004 as co-owner of a then-progressive financing boutique specializing in private advisory services. After selling this company in 2013, Dennis continued to advise private individuals and entrepreneurs on financial matters, combining this with interim assignments. In the years that followed, he worked for a broad spectrum of clients, including accountants, insurers, and banks. His assignments spanned diverse areas, from pension and financial advisors to CDD/KYC analysts, special management, and the acceptance and assessment of complex residential mortgages through the intermediary channel.
In 2001, he completed the financial planning course and the CFP certification (formerly FFP certification), and in 2003 he also completed his Master of Arts in financial planning at TIAS Business University in Tilburg.
At Adelaer, Dennis uses his knowledge and experience to further professionalize the internal organization of Adelaer’s various departments and ensure optimal collaboration. This includes the further development and rollout of the loan management system and, ultimately, enabling advisors to provide their clients with optimal advice and support throughout the financing process.
