Dr T is a no-nonsense straight to the point consultant. I have always left his clinics full of hope, even though it appears that my condition may require ongoing antibiotics to keep SIBO symptoms at bay. He makes me feel as if I matter.

It was only a telephone conversation so a lot of the above did not apply. The doctor was a little late, but gave a valid reason, and all in all was very good

Here is my feeling regards last conversation. He is everything you want in a doctor and a colleague. He makes you feel comfortable the minute you interact with him. I would describe him as sophisticated, efficient, calm, knowledgeable and a attentive person. It is an honour for me to know him and work with him.
