Omar has helped me greatly this past year.
I came to Omar with moderate depression,
each session Omar put me at ease, I learned mindfulness and meditation which helped to alleviate symptoms of depression.

Omar is a very professional, kind and understanding person. I would definitely recommend Omar to anyone who is in need of help with their mental health
— Therapy Client
I have suffered from anxiety since early childhood and more recently from generalised anxiety.

I have completed a mindfulness course with Omar. The daily meditations have been helpful and mindfulness has helped me with acceptance which I have found very difficult.

I have done some cognitive behaviour therapy with Omar. He has taught me a range of strategies to help me cope with anxiety. He explains things clearly and has given me a better understanding of my problem.

He is a good listener and is easy to talk to. I feel that Omar has a deep understanding of his subject and is able to adapt this understanding to the individual rather than just following formulaic procedures.
