Dr. Madievsky is an excellent doctor who really cares about his patients. When he learned of my poor heart condition, he recommended I take the Cologuard Test because a colonoscopy has some risks for heart patients. When I kept having trouble getting a proper sample, I called the office and he made time in his busy office schedule to talk to me over the phone. Because of his patience and knowledge, he calmed me down and encouraged me to stick with the Cologuard Test, when he could have easily used my symptoms as an excuse to get a colonoscopy, which is way more money for him. I appreciate that he took more concern for my heart than I did. I even asked if a colonoscopy was a better option. He told me to make every effort to get a proper stool sample and don't rush. Anyway, for me character is as important as knowledge, skill and experience, and Dr. Madievsky has all of the above. Thank you so much, Dr. Madievsky

Amazing experience seeing Dr. Madievsky! He's got caring and attentive staff, was able to see me on a short notice, due to my semi-emergent circumstances. The doctor was very thorough, and took his time to go over all the medications, lab work, imaging, and other physicians' notes, to provide his opinion and recommendations. Highly recommend this office and Dr. Madievsky specifically.

I am happy with the doctor, but office system needs improvement. I had to spend time filling portal questionnaires, then pdf questionnaire with similar questions, then text was sent to do it again before appointment and when I showed up for appointment, I had to do it again. Rather frustrating waist of time.
