I like Dr. Callsen. A lot. The more we are work together, the smoother it is seemed to be. I assume, she is, too, accustomed to my accent, and understands me better. She is thoughtfully makes her executive decisions with her knowledge and experience in her field. I appreciate it.

Dr. Callsen is incredible. She saved my life last year, and continues to be extremely responsive, professional, and solution-oriented.

Dr Callsen is first-rate. Because I'm HCV positive, she pushed me to see a hepatologist. That in turn resulted in my being treated SUCCESSFULLY for hepatitis C. I realize now that though I appeared to be "asymptomatic," my fatigue over the past decade or more was very likely a result of the fact that I was in fact responding to the hepatitus C. THANK YOU DR CALLSEN and also [staff].

Dr. Callsen has been my primary physician for years, and though I've moved almost 2 hours away, I can't give her up. She's always attentive, answers my very many questions with useful information, and provides excellent guidance. Thanks to her recommendation, I've gone from severely obese to overweight over the past 15 months.
