EXCELLENT Based on 21 reviews Posted on L BTrustindex verifies that the original source of the review is Google. As a mother, I spent many years worrying about my daughter without fully understanding what was going on or how best to support her. It was only when I took her to see Dr Cappai in August 2025 that things finally started to make sense. I had spent a long time researching psychiatrists before finding Dr Cappai and immediately felt she would be the right person for my daughter. Before we had even become patients, she personally took the time to call me, offer reassurance and advice, and later checked back in to see how my daughter was doing. I was incredibly grateful for her kindness and support during a very difficult time. Since her diagnosis, I have seen a real improvement in my daughter’s wellbeing and confidence. Dr Cappai is not only extremely knowledgeable and experienced, but also genuinely empathetic and kind. My daughter immediately felt at ease with her and has always felt listened to and supported. Dr Cappai has consistently gone out of her way to help, even making time for my daughter when fully booked and showing understanding and flexibility when she could quite easily have charged full fees. We have received exceptional care and support from both Dr Cappai and the team at Diverse Minds Clinic and I would not hesitate to recommend them.Posted on Yessica Castillo MariñoTrustindex verifies that the original source of the review is Google. I am very glad I met Dr Cappai. She has supported me from the beginning and given me many helpful recommendations for managing my ADHD. She has also been available to answer emails outside appointments, and I felt well supported throughout the process. I am now starting medications, and she has been very helpful to help me manage side effects as well. I am having monthly online appointments at the moment and everything is going well so farPosted on favio castillo meloTrustindex verifies that the original source of the review is Google.

Dr Cappai helped me through my journey and was instrumental in improving my mental health. I had an online assessment for ADHD and Autism and I was also diagnosed with depression. She has been extremely helpful and supportive, and after a few months of treatment, I can already see a marked improvement and am enjoying life more.Posted on elettra guggeriTrustindex verifies that the original source of the review is Google. I had a very good experience at Diverse Minds Clinic and Dr Cappai helped me in my journey to get a diagnosis of ADHD. I met Dr Cappai during an online assessment and I liked the flexibility of the appointment and her availability to explain some point of the report that we're not clear.Posted on Nicole WrightTrustindex verifies that the original source of the review is Google. I had been waiting years knowing that I may have ADHD but being too scared to confirm this. I also did not want a label. I decided to have an assessment when I realised a formal diagnosis does not make me a weaker person and gives me access to doors that I don’t have to open if I don’t want to. Dr Cappai was very kind, and I felt at ease talking with her.Posted on Lewis EvansTrustindex verifies that the original source of the review is Google. I had an ADHD assessment with Dr Cappai. I did not know what to expect from this assessment and was open to any conclusion. It turns out my current problems stem from separate issues, and a diagnosis of ADHD was not confirmed in my case. This was an eye-opening experience for me. I wanted some clarity and Dr Cappai went above and beyond to assess my background and make me feel at ease. I know some people would be disappointed not to receive a diagnosis after they have identified on social media trends for a while. For me it was a revelation and it was proof that Dr Cappai has strong ethics and high moral principle and I will continue to work with this doctor.Posted on Grant BaileyTrustindex verifies that the original source of the review is Google. I was sceptical of buzz words and popular diagnosis such as ADHD and ASD but deep down some of the symptoms and traits resonated with me. I had an assessment with Dr Cappai for curiosity most of all, and I discussed for several hours my issues with her; I was impressed by her thorough approach, and her final opinion was based on evidence rather than rushed. I am also very grateful as she was not quick to jump to treatment with medications and gave me options to work with. Throughout the whole process I felt heard and empowered to make my decisions, which seems a rare privilege nowadays!Posted on Miriam HollowayTrustindex verifies that the original source of the review is Google. I became aware of ASD only after my 17 year old daughter was diagnosed with it. I must admit I did not have any awareness and thought that autistic children were only the stereotypical ones we all know about. As it happens ASD runs in family and I also (not too surprisingly) received a diagnosis. Autism is not something that you can treat with medications. There is so much more that must be explored and medications are never going to be the solution. I am very grateful to Dr Cappai as she has helped me develop more awareness in this condition. With this fresh awareness I can be a better person towards myself and my daughter.Posted on DanielaTrustindex verifies that the original source of the review is Google. I have been on the waiting list for an ADHD assessment for over two years and because I was not receiving the support I desperately needed, my life was falling apart. I had problems at work and in my relationships and I decided I could not wait any longer. Dr Cappai was very kind, warm and emotionally intelligent during the assessment. I was diagnosed with ADHD, and she gave me many tools to implement to improve my situation. I am very glad was brave and I am now taking positive steps to improve my life.
