I would recommend Dr. Koerner because he was very personable, took the time to go over my reports with me and didn't rush me out. Recommended me to another doctor to possibly help me where he couldn't. I think that just all around he was a pleasure.

Dr. Koerner is patient and understanding, especially with older patients. He visited my mom who had 2 neck surgeries in 2 years and still suffered with neck discomfort. He explained her condition, was very patient with her questions, and offered constructive options rather than just stare at her blankly. He is an asset to his field. While her condition may improve just slightly, he gave her encouragement to continue doing what she is doing to maintain a positive outlook.

Dr Koerner was patient and understanding. He took his time and explained my condition in easy to understand terms. He also made valid recommendations.
in Leonia, New Jersey |
Dr. Koerner treated me for traumatic spine injury following being struck by a vehicle while riding my bike. I did not know or choose him as my physician, but am so thankful he serves trauma patients at Hackensack UMC. Dr. Koerner was empathetic and compassionate even in the hectic and stressful setting of the trauma area of the hospital. His positive attitude and smile encouraged me as I faced the disappointment and uncertainty of a diagnosis of multiple vertebral compression fractures.
