I couldn’t recommend Alex enough. I sought help from Alex due to burn out at work which resulted in increased anxiety and low mood. I was at a very low point but Alex helped me through this, teaching me how to think differently and how to refocus my life with me and my family at the centre rather than my job. He utilised different techniques of CBT and mindfulness and gave me practical ways to deal with my anxiety. I am now in a place of happiness and fulfilment but I also now have the tools to deal with situations or times when I can become overwhelmed or anxious. Alex was always kind and patient and I will be forever grateful. Thank you.

Hamilton is a phenomenally good therapist. With his help I was able to get my OCD under control in fewer than 6 appointments. Hamilton is also funny and highly personable, making the appointments a pleasure to attend. Prometheus were efficient at assigning me a therapist and their therapy rooms are lovely.

Hi Linda, I just wanted to pop you an email to update you and say a massive thank you for all of the work you did with me last year. Over the last month, I have flown by myself to Australia and explored Indonesia with just one other friend. I have spent over a month away from home on the other side of the world. I experienced little to no anxiety and was absolutely fine the whole trip. It has been the most amazing month I wouldn’t have been able to do this without your help.

I went to Donna at Prometheus for EMDR with some scepticism as to whether it would help, but the therapy (and the therapist, Donna) was amazing. After 4 sessions I felt completely different, my whole thought pattern had changed and was calm and I felt free from all the things we had discussed and excited for the future, thank you.
