Mr Matheiken has been a full-time NHS Consultant in Vascular and Endovascular Surgery since 2013 and an expert medical witness since 2019.

His well-established medico-legal practice reflects the wide domain of his own clinical work, with a particular interest in the prevention of major lower limb amputation and the treatment of diabetic foot complications.

His instructions presently apportion into a 65:35 claimant vs defendant ratio. He is receptive to urgent deadlines, over and above standard turnarounds of 2 weeks (short advice), 4 weeks (screening), 6 weeks (CPR) and 8 weeks (CnP).

His medical reports and legal interactions are notable for their depth of data analysis, meticulous attention to detail and explicit clarity with which complex vascular surgical intricacies are explained in lay terms.
