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.
