    GastroCare LI is a clean, neatly organized G.I. doctors location. From entry seating to exam room…read moreall was orderly and pleasant. While waiting in exam room they do have electronic sign board with scrolling medical knowledge that you can read while waiting. The board is interactive where you can touch to advance forward. It even has a drawing tool that the Dr/patient can use to show/pinpoint the pain areas, which is pretty cool to be interactive and communicate in different ways effectively. This was my first ever visit to G.I. doctors office to address potential concern and Dr Brandon Rieders [Jr] was very thorough on questions, physical exam and advise on possibilities of cause and all available options forward that are available. We were easily able to agree on next step actions and followup appointment easily made upon exiting. All staff members around him were pleasant and kind to interact with as well. This office upon 1st visit and glance seem to fluidly be working like a well oiled machine, and look forward to results and next visit if needed.

    This was my first visit to this facility. I was pleasantly surprised by the level of commitment to…read morepatient care from reception to physician. Reception was very courteous checking you in.

The result: almost no waiting time (15 minutes MAXIMUM) at his office. He has a great referral network. He's affable yet efficient, good- humored, and he takes your health and privacy seriously. When he has test results for you, including and especially STD/STI/venereal disease tests, he himself calls you. If you don't pick up, then he leaves you a message telling you to call him back, but doesn't leave the results of the tests themselves in the message. Those he ALWAYS gives you over the phone or in person. He delivers the good news briskly, and you feel he is as happy and relieved as you are. I've also seen him deliver uncertain or bad news with kindness and understanding, spending hours with her and her family discussing which option would be the better one. It was a contentious proceeding, but he handled it with diplomacy. professionalism and patience. The process lasted for several hours, concluding in a major decision that prolonged the patient's life. He has embraced the latest technology and pioneered an easy check-in process that streamlines the provision of patient information including insurance.

    Nice, pleasant and thorough the colonoscopy was quick well done. Doctor is congenial informative.read more
