The Founder

For over 20 years, the real estate market in the Rhine-Main area has been the passion of Markus Kullmann. This passion has been a consistent thread throughout his life, from his studies (Diplom-Betriebswirt BA in Real Estate Management) to his self-employment. 

During this time, he has primarily specialized in the office asset class. 

Clients particularly value his genuine passion for the field, respect for entrusted values, honest advice, and personable support. 

He has built his extensive experience and strong network through leading positions at renowned companies in the industry.
