Officers

5

Three of the 5 officer records shown for Hajo Siewer Jet-Tours GmbH are current appointments, filed with Handelsregister (Commercial Register). Thorsten Kleine (appointed 2011-08-30) serves as Geschäftsführer (managing director); Jan Ole Potinius (appointed 2015-02-20) and Stephanie Prummer Alves both serve as Officer. The remaining 2 records shown (Andrea Bungart and Edgar Nemenz) are former appointments that have since been resigned.

The register reports 6 officers in total, including past appointments, though only the 5 most relevant records are shown here.

Management authority at Hajo Siewer Jet-Tours GmbH sits with these individuals, not with shareholders, who are covered separately and hold ownership rather than control.

The source filing doesn't specify representation authority — whether officers can act individually or must sign jointly to bind the company — so that detail isn't available here.
