Doctor Te Slaa is a trainer since 2006 connected to thegroup of General Practitioners of the AMC in Amsterdam. Every year a new doctor will be trained to be a GP in this practice. This doctor will perform his/her own office hours and can easily consult the trainer. The doctor in training meets with the trainer on a daily basis.

Doctor Te Slaa is frequently educated in guiding and training the new GP, but also in new and important aspects of medicine at the AMC.
