Why Birch Tree Psychology?

What makes us different from other clinics is that we have invested therapists who are committed to helping you to achieve your goals.

We have a wide range of group classes and stand-alone courses that may be of benefit to you and can be used in conjunction with individual therapy or as a separate self-awareness and learning aid.


We also have numerous useful resources which are free to download and can either supplement your individual therapy or be used in isolation of therapy.


We believe that being able to access personalised and tailored support is vital. We therefore offer a variety of therapy delivery models to allow clients increased choice in how they would prefer their therapy to be provided.
