I suffered from gut problems for years (it's something that runs in my family). I finally ended up in the ER and spent 3 days in hospital. As part of my recovery I went to see Dr Drennan to figure out the root cause and see if anything could really be done. Dr Drennan was super supportive and patient in explaining paths forward and executing a diagnosis (which took a long time over several weeks because there was a lot of investigation required). Dr Drennan helped figure out the core problem and a path to solving it - I've felt great since! I thought he (and his staff) was always kind and empathetic and it was clear from the options he presented he was up to date on the very latest in the field. I'm someone who hardly ever writes reviews but I wanted to sing Dr Drennan's praises for all he's done for me. I can't recommend Dr Drennan enough and I wouldn't go to anyone else.
