"1) I submit this rating as a board certified family physician myself. 2.) He is rude and inappropriate with my mother, telling her that she needs "to poop more" while not even doing a physical exam. (She was later diagnosed with diverticulosis.) 3.) When she had recurrent urinary tract infections, he repeatedly recommended "end of life care." My family begged him for a urology referral, and the urologist in turn referred her to an infectious disease specialist. (Mom takes some tablet - Methenamine - now, and she has had no UTI's in eight months. 4.) Some years ago, both Dr. Cantorna and his Nurse Practitioner placed Mom on two potent diuretics and a.) apparently did not communicate with each other, and b.) apparently failed to follow her electrolytes. My mother's sodium went so low that she passed out and broke several vertebrae requiring long term hospitalization and rehabilitation. (Her sodium was so low - panic level - upon her hospitalization that she could have become quadriplegic ...
for life as a result.) 5.) Dr. Cantorna most recently saw my mother in follow-up after a heart valve replacement done at Rush Hospital in Chicago. She was on a new medication that is known to cause tiredness and weakness, but he told her to just keep at it for another 6-8 weeks. He also mistreated a minimally elevated potassium level by stopping ALL of her potassium when she takes 80 mg of Lasix (furosemide) per 24 hours. 6.) I would not recommend this physician. "

Data Transparency and Trust: Understanding WebMD Doctor Listings and Reviews

We know that finding the right doctor or provider is important to your health. That’s why we want to ensure you have confidence in the provider profiles and listings you see on WebMD Care. Our provider data is sourced from the physicians themselves as well as publicly available databases. Any doctor or provider who claims their profile by verifying themselves can update their information and provide additional data on their specialties, education, accepted insurances, conditions they treat, and procedures they perform.

All the physician and provider reviews on WebMD Care are provided by users just like you. Knowing these reviews provide insight into how other patients feel about a doctor, we maintain internal policies and protocols to ensure the quality and accuracy of all reviews. Providers are not able to remove or modify reviews on their own. Reviews can only be removed after an internal review by our customer service team.

We value your input and encourage you to reach out to our support team if you encounter any issues.
