    Very grateful to be referred to Dr Kallis who was so kind and respectful, and such a fantastic and professional clinician. He took the greatest care to ensure I understood exactly what was causing my symptoms and thoroughly investigated the issue to help ensure I get back on my feet. His wonderful secretaries were also just so kind and extremely helpful; many thanks to them as well for chasing MRI images on the weekend! I have no hesitation in recommending Dr Kallis for his extensive knowledge, expertise and wonderful bedside manner, and would most definitely return to him for any problems in his knowledge area in future.

    I had my first appointment with Dr Kallis via zoom earlier this week and I found him to be empathetic and he listened to all my problems and responded in a way that was extremely comforting. He was attentive to my fears and needs and he was reassuring without giving false hope. I feel I am in good hands and I am hoping following scans and blood tests he will be able to help me.
