Dr. Lars Kleining is a board certified specialist in plastic and aesthetic surgery as well as hand surgery. Besides, he’s an ambulance. He works in the private clinic Praxis Klinik Pöseldorf in Hamburg. Several times a year he gives courses as a teacher of the Allergan Medical Institute, in which  doctors can learn the aesthetic treatment with botulinum toxin A and hyaluronic acids according to the method of the MD Codes™ from Mauricio de Maio. In this context he was trained by internationally renowned doctors and communication trainers and is himself a speaker for the Allergan Medical Institute.

Besides his work as a physician the professional journey is now taking him to explore better ways of working as a health professional, learning more about #teal organizations and #newworkinhealthcare. Pursuing this goal different projects started in 2020 including further trainings in eHealth and self-organization.

Prior to this activity, Dr. Kleining worked as a senior physician, among other things as a specialist for hand and micro surgery. This gave him insights at various clinics not only into the most varied treatment options, but also into the social, political and business conditions. In addition, the career path was accompanied by many journeys, including a one-year trip around the world. This resulted in friendships with people who came from cultures of six different continents. In conversations with very different people, Dr. Kleining has developed a deep understanding of other cultures. He also became very aware of how valuable and beautiful nature is. Dr. Kleining is a convinced optimist.
