Dr Zar and his associate Geraldine Munday were incredibly helpful and responsive. As an American living in London, I was scheduling my first doctors appointment in the UK. Geraldine patiently walked me through the process, always at the ready to answer my questions about scheduling a lower- and upper-GI and what was necessary to prepare. Dr. Zar was informative and thoughtful before, during and after the procedure, and had such a wonderful bedside manner. His sensitive and responsive approach to me as a patience made me feel like I was in the best of hands... which I was! I highly recommend Dr. Zar and his team.
