I'd never seen Dr. Callsen before. I needed to get a pre-op physical done promptly & she was available. She was good: attentive & thorough. She seemed to pay more attention to me than anyone else I've ever seen in this practice. Maybe that's because I have a cancer diagnosis or something. She didn't seem to get distracted by telling me to lose 10 pounds or dismiss me with ""it's a virus, ride it out.""

Negatives: The appointment had to be scheduled 7 months in advance, While prep work (weight, blood pressure, etc.) was actually started early, Dr. Callsen arrived 20 minutes after the scheduled time. Positives - she and I go way back, we communicate well, she knows my history.
