Dr. Stassen is the BEST doctor. Avera is sooo lucky to have him. I never want him to retire because I don't know what our family would do without his care! He's the BEST!

I'm not sure my primary reason for the visit was addressed. I needed a blood lab for the heart hospital. No lab seemed to be ordered. I hope the lab I received satisfies the cardiologist
