- Assessment felt rushed and overly tick-box driven. Questions were rigidly counted against a checklist with little follow-up or context. The clinician’s phone rang multiple times. My difficulties were largely dismissed because I’m still functioning at a demanding job (being the only bread winner..) with no exploration of masking or coping cost. A non-diagnostic concept was raised and I was sent a YouTube video, and ADHD coaching was promoted during the call. Overall it was a terrible experience
- Dr Mashru is a great doctor who I was able to get an appointment with more quickly than the two dozen other clinics I contacted when I needed a medication review. He is approachable and knowledgeable, and, thankfully, takes previous diagnoses and doesn't waste time.
- Dr Mashru is very approachable and immediately put me at ease. My symptoms were not clearcut so Dr Mashru extended my consultation time, without any additional cost, to ensure he had all the information he required to determine if a diagnosis was appropriate. He also provided a further short call and some email back and forth to provide reassurance and advice. Dr Mashru was thorough and clearly very competent. I would not hesitate to recommend him.
- Dr. Shyamal was amazing. Friendly and caring. He listened to me carefully and allowed me to explain all the different aspects of myself and my needs. I am pleased that I made the choice to go with him for my ADHD assessment. I left his office feeling heard and validated.
- Dr Mashru has truly given me a new lease on life! His expert care, patience and advice have made a world of difference in my health. I felt heard, understood and confident in every visit. Highly recommend for anyone seeking exceptional care!
- Highly professional with the ability to apply his depth of knowledge, Dr Mashru is one of those rare practitioners whose experience and insights feel intuitive in conversation, even on difficult issues. I would recommend consultation with Dr Mashru to those on their ADHD journey.

- Dr Mashru is quite simply brilliant. He is open, friendly and put me at ease straightaway. He is also extremely insightful and very knowledgable. I would highly recommend him.
