In patients' words

"Dr. Knopp is outstanding! He cares about his patients. His staff is professional, efficient and caring."

— Healthgrades reviewer

"Problems with the preparation and instructions for a colonoscopy. They were unclear and counterdictive. When those issues were brought to Dr. Merkley’s staff they were ignored and the staff was not interested in the problems."

— Vitals reviewer

"My extreme frustration is with the "patient access center" and inability to get through to the office... If a patient is having a surgical complication or medication concern it should not take calling multiple times on hold over 10 or more minutes."

— Birdeye reviewer for Lexington Clinic
