Dr Callsen is an excellent physician. She has a very broad knowledge base and she listens to her patients. While she comes off as reserved, she's also quite companionate. She may be a little late sometimes, but she always gives my visit the time it needs helping me to understand more about my health and allowing me to be a partner in my own healthcare.

Dr. Mary Callsen meets my needs as best as she can given the limits of time allotted for a physical. We may have an opportunity to talk again with respect to my lab results. Dr. Callsen gave me unlimited time when I needed support after a shoulder fracture last summer. Feeling lucky to have her as lead for my medical team.

Dr. Callsen is the most knowledgeable, comprehensive, and thorough professional that I ever encountered. She makes recommendations based on empirical data and yet allows the patient to be the final decision maker. Somehow she finds a few moments to listen to the patient. This visit was for approval prior to an operation. An Internal Medicine doctor pulls so much critical information together. It is wonderful to know that I am fully prepped.

Dr. Mary Callsen listened to my apprehension on taking a cholesterol lowering statin again after I went through an unpleasant experience with simvastatin a few years back. She told cholesterol, unfortunately, goes up with advanced age and advised to take a different statin, Atorvastatin, which agrees and shows good results with many patients. So I started to take her recommended doses of 10 MG daily and it already showed great results. So far I tolerate the new statin quiet well.
