"I was in the office for a physical check-up and to schedule surgery for an umbilical hernia. The office was spotless and tidy; the waiting time was minimal. Dr. Knapps invested the correct time for my review; he was very attentive to my questions and clarified all my doubts. The surgery was scheduled, as well as the subsequent follow-up consultation. I widely recommend Dr. Knapps as a dependable and technical skillfully surgeon."
