A consultant who genuinely cares. I think I’ve been one of Alissa’s more challenging cases as getting to where I am now has been a very long process of trial and error. Understanding the complexity behind digestive system problems and Crohn’s is not easy but Alissa brings a wealth of experience to the table and has an excellent rapport with her patients with her kind and thoughtful approach. I had an appointment with her yesterday and as always, I felt she took a real interest in my care and I never felt rushed, even though I’m sure we took more than our allotted amount of time. Ultimately, there is presently no cure for Crohn’s but Alissa is really up to date with the latest treatments to manage the illness and I feel lucky to have her as my consultant. Thank you Alissa!

Dr Walsh took time to get to know me, understand my medical history and to understand what I hoped to achieve from my appointment. She more than satisfied my needd and wants by considering my total health needs, and agreeing priorities rather than advising on just her specialist area of medical expertise.
