I like that the doctor is direct, decisive and clear. It is obvious that he has a lot of experience and knowledge.
*Dr. Adamany was great recommend to family.
I forgot to ask about Pantoprazole SOD proscription, and Doctor didn't mention it either. The colon issue was handled very, very well, but I had some ulcerated issues with my stomach previously, and I should have asked about that and not just my esophagus.
Dr. Adamany is an excellent doctor and I have recommended him to friends and family in the past, and will continue to do so.
Nice doctor.
