I have been suffering from my condition for about 15-20 years, but nobody has been able to diagnose it. It was as though I was the only person with that problem. Since Lou Gehrig has a disease named for him, I wanted my condition to be named after me. Fortunately, Dr. Brenner had the answer. Actually, he had the answer some time ago, when all I had was a telephone appt., but while he put in a referral to SRAL for biofeedback, the therapist, who said she knew what she was supposed to do, did something else. This will be my second try to get biofeedback. The only problem is that it took far too long to get the appt. I put in the request last summer. Was Dr. Brenner a consultant to God when He designed Adam?

Dr. Brenner is highly regarded in his field. But he is utterly Western medicine/give it a drug focused. He told me "there is no such thing as leaky gut" which I believe is held to be true. People are voting with their feet and going to functional doctors, even if they don't have that leaning, because Dr. Brenner and colleagues are so locked in on GI in islolation of the ecosystem of the body that I and others end up with several doctors and numerous drugs that are not ideal to try and fix things. Instead, let's use the tools that are are research based, but be open to outside voices that are solving GI problems as as reflection and driver of overall health outcomes.

He’s simply the very BEST in his field. I’ve see more gastroenterologist in the past 37 then I can count. When I was referred to him my life changed. He understood! He didn’t just hear what I had to say he listened. Now, I am able to be more independent yet when an issue arises I know I can send him a message and he will answer and give me direction. I only see him on average once a year but it’s an appointment I look forward to. There is nothing better than a physician who looks and treats each patient as an individual. He did testing to verify what was going on. He helped with documenting it and that’s what brought about my gained independence. Dr Brenner will always be considered a silver lining in my book. I can’t thank him enough!
