Clear explanations of all.my questions. Felt reassured and confident with Doctor's expertise. I felt that my treatment was personalised to my lifestyle and needs.
Dr Kariyawasam is really friendly and very knowledgeable. Offered thorough checks and explained results clearly. Would definitely recommend.
Dr Kariyawasam was very sympathetic and understanding about my symptoms. She explained things that two consultant gynaecologists I’d seen previously hadn’t. She was very clear, we discussed treatment options and she has a great personal manner. I was very pleased and impressed with my consultation I had with her.
A helpful consultation with clear advice and a personalised treatment plan. I felt listened to and supported.
The administrative handling of my appointment was SURPRISINLY unprofessional, particularly in relation to the secretary Georgia. Although I responded promptly with my availability for the video/telephone consultation, I never received confirmation of the appointment. On the day of the consultation, I emailed again to request the video link but received no response. When I called, I was told my emails had been missed and the appointment had never been confirmed, without any apology. The same thing happened AGAIN when I accepted an alternative slot later that day—my confirmation email was overlooked AGAIN, leaving me to chase for updates shortly before the appointment. In contrast, the doctor was professional throughout. My complaint relates solely to the administrative communication and organisation, which fell WAY below the standard I would expect.

Thank you for taking the time to share your feedback. We are very sorry to hear about your experience and we sincerely apologise for the frustration and incovenience caused. On this occassion Dr Kariyawasams usual secretary was on leave and your appointments were being managed by a member of the team providing sickness cover. Unfortunately on this occassion your emails were overlooked, and we recognise this resulted in poor communication and unneccessary stress for you. We appreciate you highlighting these issues as this enables us to review our processes and ensure improvements are made to prevent this happening again. We are pleased to hear that your consultation with Dr Kariyawasam met your expectations, but we fully accept that administrative support you received fell short of the standard we strive to provide. Please accept our sincere apologies and thank you again for bringing this to our attention.
I have had a great experience with Dr Kariyawasam. She is professional, knowledgeable, and takes the time to listen to my concerns and explain everything clearly. I feel comfortable in my appointments with her and leave feeling confident in my treatment plan. The staff were also friendly and efficient, making the entire visit a positive experience. I would highly recommend this practice.
Very well mannered - helpful and knowledgable, really seemed to care.
Dr Kariyawasam was really helpful and explained everything clearly to me, including the reasons for symptoms and possible solutions
Dr Kariyawasam was professional, friendly and above all, kind. I felt like I could cover off everything I wanted to speak about with ease and she was clear in next steps and processes. She made me feel at ease and confident in next steps. I couldn’t fault her.
I have been lucky to have worked with Dulmini for a good 7 year period. Her clinical acumen, compassion and professionalism is par excellence. Under her care, you can be sure of receiving highest standards of medical support. I am confident that you will not need to look any further once you have been in touch with her.
