  • Dr Warner was genuinely exceptional. I had been quite dissatisfied with quality of gastroenterologists I had seen prior. However with Dr Warner, it was a completely different experience as he took time to really look into my prior medical history, look into the smaller details to work on an action to plan to find out was was causing the bloating. I’m very happy with my service as we’ve found out the root cause and a solution. I can’t thank him enough and would recommend him!

  • It is very difficult to find a parking space when visiting Blackheath Hospital. I had an early appointment (8.15am) and it wasn't helped that the gates to the small car park didn't open until 8am. This wasn't made clear on the website. I did try looking for spaces in nearby roads as suggested on the website, but they are all permit parking.

  • Dr Warner was absolutely incredible. He was informative, sensitive and professional. He explained everything clearly and worked very quickly to ensure I got the treatment and answers I needed, I am truly overwhelmed with how he managed to give me the diagnosis I needed so quickly, but never rushed. He was considerate and careful and I would recommend him in a heartbeat. Thank you again

  • Excellent doctor, very attentive, really listens to me and explains exactly what's happening, as well as next steps, and always involves me in the decisions. He's absolutely my go-to gastroenterologist, as he doesn't dismiss anything but rather discuss possibilities while reassuring me.
