I use various approaches to work with clients, such as CBT, Psychodynamic, humanistic and so on. Also, being that I also specialise in bereavement counselling, I also use grieving models to help and support people grieving the loss of their loved ones.
Moreover, I believe that all negative or irrational behaviours are internalised somewhere along the way, which means that most of the time, they derive from past unpleasant events, which is why it is necessary to use different approaches, as different clients attend therapy with different problems.
