In conversation with host Cedric Pick, the currently in-demand specialist for internal medicine talked about the latest developments with the coronavirus pandemic, the latest political decisions at state level plus his wide range of duties at the Werkself. The 57-year-old medic also provided insights into the club’s hygiene protocol, the different testing procedures as well as the handling and chain of action with positive test results as was the case recently with Werkself defender Edmond Tapsoba after his return from international duty.
The Leverkusen-born doctor, who, in addition to his role at Bayer 04, is the director of a group practice in Leverkusen-Quettingen, outs himself in the entertaining dialogue as a longstanding Bayer 04 fan, a supporter of the Werkself from the stands long before he became the club doctor. In his very first season of his employment at the club, which ‘Kalla’ describes as a coincidence, he was able to follow the historic 2002 season first hand with the three runners-up finishes – so defining and indescribable as many short-notice and short overseas trips involved with transfers.
In the entertaining discussion, Karl-Heinrich Dittmar talks about his values, his multifaceted workload, lack of time and his pride in the club’s training and rehab centre the Werkstatt. The father of four not only revealed a great sense of humour but also loads of empathy.
In addition to the opening jingle, the Werks11 podcast also includes other items (including ‘My top 04’, ‘Either...or...’). Other guests speaking are his former boss Reiner Calmund plus former Bayer 04 keeper René Adler who surprise Karl-Heinrich Dittmar with a question.
Moreover: From now, the Werks11 podcast will be available every two weeks. The next episode will be available on Tuesday 15 December.
