Patient Reviews
Jan 07, 2024
The previous review, which blows my mind that it is negative, makes me truly think this “patient” was never even seen or a patient of Dr. Unger’s. If they had been a patient, they would’ve known first hand how remarkable this physician is. It is a breath of fresh air, to have this level of care and compassion, along with professionalism and knowledge, I am at ease knowing my ailments are not only treated by a family physician with multi specialties, but not missed or bypassed like 99% of the other doctors nowadays. Dr. Unger diagnosed me when others couldn’t even figure out what the problem was. I am one of many, where Dr. Unger has saved my life. I will forever be grateful for the quality of life I now have thanks to him. He is truly the BEST there is literally! Staff is also amazing and never waiting in a full lobby with other patients. He is never rushed with my appointment and answers questions in great detail in a manner that it is understood. Couldn’t speak enough of Dr. Unger.
