He is very knowledgeable and kind. He is not in a hurry but confidently and calmly explains everything and then asks if you have any more questions.

He was friendly, and spoke in non-medical terms so that I could easily understand my prognosis. He's been great.

Dr. Aranez is a one of a kind doctor, always considerate, always kind, and always puts his patients first. He is an anomaly in today’s world of healthcare, which is a sad thing to say, but speaks to his excellence. I’ve messaged him on MyChart and he promptly replies same day, sometimes within the hour. Do you know how reassuring that feels on my end as a patient? There are no words to describe how good that makes me feel. That my health is in the hands of someone who cares that much. Fellow doctors of MemorialCare and all healthcare organizations have something to learn from Dr. Aranez. He is a breath of fresh air in this generation of physicians and I hope MemorialCare recognizes him for that.

He was very thorough in communicating possible ways of dealing with the cysts in my pancreas. He was exceptionally personable and spent extra time explaining my issues. He was open and friendly!
