I thought my apt was 2:15pm, when I arrived they explained it was actually10:15am.They asked Dr. Hasselbacher if he would see me. Answer was yes because of a cancellation, he would be able to see me. I only had to wait 10 minutes. Everyone was very helpful and professional. When I got home I looked at my schedule and because I was sick I had to reschedule my original 2:15pm appt and Ihadn't changed the time.

Dr Hasselbacher is the absolute best! He is professional, courteous, empathetic, and personable. He knows his patients medical history and his knowledge in how to treat their pathology is unsurpassed. He saved my life by being proactive when I was in a health crisis. He is continuing to improve my life by following me on my health journey. I couldn't be happier with Dr Hasselbacher as my pulmonologist.
