Testimonials

"Clean, bright and modern premises with state of the art facilities. Staff are friendly and welcoming, and the MRI technician was super friendly and professional. I was very nervous about undergoing the MRI but the technician was very empathetic, reassuring and made me feel at ease. I can't thank her enough. I would definitely recommend Lyca Health to friends and family."

"The services at LycaHealth Clinic, starting from the reception, are 100% client-focused and excellent! I had issues after becoming premenopausal about a year ago and just turned 50 this year. During this time, I started experiencing things such as fibroids, pounding migraines, high blood pressure readings, high cholesterol readings, pre-diabetic condition, and stomach pain nearly 5 times a week. The week I started my treatment all the pains have disappeared. I haven't used any painkillers for almost 3 months. Now I'm walking frequently and averaging over 10,000 steps over 4 times a week, and I'm really re-establishing my relationship with food. I cannot begin to thank LycaHealth, Dr. Siva Sivappriyan and Dr. Sharma enough."

"Professional and friendly. I required an MRI at short notice and Lyca Health did everything they could to accommodate. The staff were exceptionally courteous and professional. I would recommend wholeheartedly."

"Satisfied all that I needed on my visit. No problems, all straightforward. Can recommend this service."

"Building was impeccable and the facilities were all top-notch and brand new. It looks more like a corporate penthouse than a medical centre! Staff were great, friendly (not too robotic) and told me what I needed. Referred me for a scan and I had it onsite - happy days! Perfect place to get everything done. Also: all covered by my insurance too!"

"I would highly recommend Lyca Health. Just had an MRI with them and it was a very good service."

"Fast, personalised attention and great staff. I went in for an MRI and everything went smooth. The radiologist and the nurse were amazing."

"Excellent service. Complete confidence in staff and they were very efficient. I'm so pleased to have found Lyca Health."

"Today I attended Lyca Health and cannot praise the service and staff more highly - amazing service."
