René Atz-Asen

There is no such thing as can’t!

The successful estateMoments team consists of experienced and dynamic people who have made their passion their profession. All employees are permanently employed and I am responsible for the management, René Atz-Asen:

After completing my secondary school leaving certificate at a business school in Munich, my professional career began in 2000 with the acceptance of a

Apprenticeship as bank clerk (IHK), which I successfully completed in 2002. After completing my training, I was called up for basic military service and then, from the end of 2003, I trained as a commercial clerk in the real estate and housing industry (IHK), which I successfully completed in September 2005. After completing my second training, I worked in the following years, first in a law firm operating throughout Germany in the area of forced administration of real estate in Munich and then with one of the largest construction and real estate groups in Germany at the time as a real estate administrator in Frankfurt am Main, before I became a real estate agent in Frankfurt am Main in 2008.

The first step to change from the administrator’s activity into the broker’s activity was not easy for me at that time, because I myself did not have a good opinion of the profession of the real estate agent due to my experience as a real estate administrator as well as other negative experiences until then. For this reason, I decided from the very beginning that the measure of my success should not be the ‘quick money’, but primarily the satisfaction of my clients and the sustainability of the cooperation with them. Since the middle of 2011 I have been working as an independent real estate agent in Berlin and I feel as closely connected to this city as I do to my profession.

In my professional life, I am thrilled that no two days are the same, that our everyday business life is ‘humanized’ and that day after day there is the opportunity to create added value with inventiveness and creativity. What distinguishes estateMoments and me in particular is that we have the unbending will to improve and we only really take off when others have already thrown in the towel.

About my private life I am happy to share with you that I am a husband and father of a daughter, live in the southwest of Berlin at the border to Potsdam and like to do gardening, if my limited free time allows it. Other hobbies of mine are gliding, hiking and badminton. As a child, I was a passionate Monopoly player, which is why you could say that I am a Monopoly player today: Practice early.

Lilly (Office dog)

Figuratively seen she has here the thickest fur

Many a letter carrier and parcel deliverer approaches our office with awe since she has been with us. For the few files that we still have to keep in our office, she is our data protection officer. Behind the initially sometimes rough shell, however, there is, as so often, a good soul who is very happy about every stroke and little snacks.
