What our patients say about us

"Dr. Tilahun,
I am writing to thank you for your excellent care when I was in the hospital the end of July into August. It was a scary time for me and my husband. We were visiting from another state. I was very pleased with the care, knowledge and concern of everyone that works there. Thank you again for your excellent care."

-- Diane (and Jerry) Sales
