  • "Dr. Andrea Fonner has been a valuable asset to my practice. Even though I am sedation certified, having an expert that can provide excellent patient assessment and provide safe and comfortable sedation to my patients has been a God send. She allows me to be more productive in a shorter period of time while providing my patients the comfort that they need. Thank you Dr. Fonner."
