- Dr Parisi is excellent. Very gentle, listens well and is very friendly. She explains every step of the treatment and is punctual. Her PA, Nikolas, is a super star! Super responsive and helpful. Would throughly recommend.
- Dr Parisi was very helpful & listened to my daughter’s symptoms. A great second opinion as our first specialist hadn’t offered any action plan for IBS management nor offered a colonoscopy for some season. Clinic staff were friendly & helpful and the hospital was spotless. A bit further than we would normally travel as live SW London but it was worth the journey. Early days as only had consultation yesterday but left feeling hopeful that might finally get my daughter some help.
- Very friendly, thorough appointment with Dr Parisi. Friendly staff at the reception, very clean establishment.
- Dr Parisi’s credentials as an incredibly accomplished doctor speak for themselves, but what makes her stand out, is just how kind and caring she is. I’ve had numerous hospital procedures/consultations with her, and I honestly cannot recommend her enough!
- Thank you so much Dr. Ioanna Parisi I really appreciate your support regards Ahmad
- Dr Parisi is an attentive specialist who advised me to do PillCam to check the state of my gut after I had pain in my stomach (IBS) for 4 years and was questioning if there could be an alternative explanation for my symptoms. It was a smooth experience, I highly recommend her!
- Easy and straightforward process from booking appointment to getting any tests or investigations arranged. All consultations were telephone which made things easier as didn't need to take time out of work for appointments. Very helpful PA who responded to all my email enquiries.
- Dr Parisi provided excellent care for my teenage son. I cannot praise her enough for her superb professionalism and empathetic patient welfare. She is quick to identify issues and how to resolve them. Her proactive follow up approach is first class.
