My name is Asaf and I am a professional tour guide. I hold a Ph.D. in Dark Tourism and interpretation of history. In Berlin I guide tours on such topics as the Cold War, the Third Reich, Berlin's Jewish Heritage, Berlin and Brandenburg's Prussian History, and more. I also guide in Potsdam, and I am certified to guide in the Memorial and Museum Sachsenhausen. I am also an enthusiastic runner and cyclist. For repeating visitors, looking for unique experiences outside the city, I guide special cycling tours in Brandenburg's northern lake district, and in the Spreewald Biosphere Reserve.
