“Dr Iroku Ugonna is kind, compassionate and thorough. He didn’t dismiss any of my concerns and it ended up being a possible life saving situation. Great staff, especially at the procedure clinic Liberty Endo on 156 William street. Saw me before and after procedure and went through everything explaining clearly and in a way a non medically trained person could understand. Apart from a little mix up with insurance and the colon prep needed I would highly recommend him and his team! Will definitely be using him again. Thank you for being a great listener and communicator. So rare these days! How medicine should be practiced always!”
