He finds ways to improve and doesn't give up until he finds what this issue or pain is or what is causing it. BTW he communicates with your doctors who referred you so they are in the loop of any or all issues learned or discovered by Dr Holt. I really like that he listens and trys to figure out the problem. He does not surgar coat or pass you on to some one else."

"Dr. Andrew Holt Is a very detailed professional physician with a great “bedside” matter. He. Is very experienced Digestive Disease consultant with years of surgical and medical work behind him. I believe Dr. Holt ‘s belief and practice is “surgery is a last resort “. I think my case with acid reflux was a real challenge as I have had stomach issues my whole life; Dr. Holt solved my case without surgery. There are other doctors in his field and I researched the “right “ doctor for me and as far as I’m concerned the only one for me."
"Dr. Holt has always taken the time to hear my issues and weigh them out. This last visit was very complicated. He took nearly an hour to listen and assess what test etc. need to be done to relieve my discomfort.
I would recommend him highly if you want a Dr. that cares and takes your interest to heart.

In fact, the anesthesiologist who cared for me recently, remembered that she had previously cared for me and was so pleasant and reassuring.
I’ve been fortunate that none of the serious medical conditions that could happen, haven’t, and I attribute this in no small part to the ongoing care provided by Dr Holt.
