He Should Mentor Young Physicians

Dr. Gregory Ackert is a top of the line physician who was able to diagnose my Ulcerative Colitis even after several other physicians were unable to do so. For a patient that is suffering, aside from understanding your diagnosis and being able to pursue viable treatment, an amiable relationship with our physicans is essential to the healing process. A kind empathetic bedside manner is a priceless quality for our physicians to possess and unfortunately a rare find in our healthcare system today. Dr. Ackert is meticulous, trustworthy and knowledgeable. He takes the time to explain and address your questions and concerns. To be able to walk out of your physician's office feeling that he/she genuinely CARES about your well being and that it is important to him/her is a true gift. I have been his patient for about 6 years and am very grateful to have found him. I work as a patient experience manager at a hospital in the NY area and work everyday to elevate the quality of care provided to patients . The quality care he provides should serve as an example for other physicians. It is a true pleasure to be his patient and I highly recommend his care and services.
