A listener nominated Dr. Robert Knox and said, "I just had my last colonoscopy and upper GI. Since I am a high risk patient, the professional demeanor of the doctor and his entire staff, greatly reduced my fear level before having this procedure. I am so thankful that Dr. Knox has been my gastroenterologist since the mid 90's. His experience, guidance and caring demeanor continues to help me enjoy a healthier life." This month's Heart for Healing honoree is Dr. Robert Knox, who receives a $30 gift certificate from the family at The Alley On Main, 223 West Main Street.
