About Dr. Athanasios Tsoumpris

Dr Athanasios (Thanos) Tsoumpris is a Consultant Psychiatrist specialising in general adult and perinatal mental health, with additional expertise in the diagnosis and treatment of adult ADHD. He currently works with the Lambeth Perinatal Mental Health Team at South London and Maudsley NHS Foundation Trust (SLaM) and has worked in the Adult ADHD Service at Central and North West London NHS Foundation Trust (CNWL).

Dr Tsoumpris has over a decade of experience within the NHS, having completed his psychiatric training at both SLaM and the East London NHS Foundation Trust.

I have felt cared for and involved in my care and decisions around my care all the way through. The care I have had has made me feel reassured and confident that whatever happens in the near future, there is a plan and support will be available if and when I need it. I have always felt respected and listened to.

Dr Tsoumpris has been absolutely amazing. The care and his approach towards me has been extremely kind and understanding which in turn gave me the confidence to be relaxed enough to speak with confidence and not to be fearful of talking. This whole experience has helped me immensely

I was really impressed with Dr Thanos and how carefully he helped us navigate our son’s journey through recent Autism and ADHD diagnosis and exploring medication for the later He seemed incredibly diligent and thoughtful in his approach. My son is 18 so technically an adult but I was very grateful that he brought me into the room a bit, figuratively and actually, so I was reassured and informed, but not so much as to take anything away from my son’s agency in what is, of course, his journey. We are very pleased to have found such a great practitioner.

I have had an excellent experience with Dr Tsoumpris so far. I've felt really listened to throughout, and all reports have been extremely thorough and considered. I'm also really happy with the provisional management plan that we've agreed, and really appreciate that this process has felt collaborative. Highly recommend.

Dr. Tsoumpris carried out my adult ADHD assessment and managed my medication titration over several months. I have now reached the end of titration and am very happy with the management plan arrived at. The assessment was thorough and the explanations of the diagnosis and treatment options were always clear. What stood out most was how genuinely collaborative he was. Decisions about my treatment were worked out together, with my own observations taken seriously at every step. He has an easy, relatable manner with none of the distant formality some patients find off-putting, and he consistently treated me as an adult capable of making informed decisions about my own care. A thoughtful and skilled clinician who helped me considerably.

I attended 2 appointments with Dr Tsoumpris as part of an ADHD assessment. He was caring and compassionate from the outset, which helped to put me at ease throughout the process. I felt he was thoughtful, listened astutely, and really took the time to thoroughly understand me as a whole person and the challenges I was facing. I would highly recommend to others seeking an assessment.

It was an absolute pleasure meeting Dr. Thanos. From the outset, his calm and reassuring demeanour immediately put me at ease, and I felt truly heard and validated throughout our interaction. I was initially anxious and somewhat hesitant about discussing my experiences and past, but he created a safe and supportive environment that made it much easier to open up. He listened attentively and patiently, especially when I struggled to articulate myself, and responded with genuine compassion and understanding. He also took the initiative to gather additional information from my partner and even called us outside of the scheduled assessment time to ensure he had as complete a picture as possible. This demonstrated how thorough and dedicated he is to reaching the most accurate and informed conclusions. I had complete confidence in Dr. Thanos’ expertise. Even though we moved through the questions efficiently, he was incredibly perceptive and managed to gather all the necessary information, despite my sometimes convoluted explanations. I would highly recommend Dr. Thanos without hesitation.

My experience has been life changing. Without the care and support of the team I would not be in the place I am today.
