"While my doctors and the nurses at Ohio Gastro have been fantastic (this review does absolutely not reflect them), billing is an absolute nightmare."
— BBB Business Profile Review"Scheduling is terrible. Trying to get someone to answer the phone is also terrible. They certainly are on billing as soon as you see a provider."
— Yelp Review"Dr. Castor agreed to take me on as a patient... I have found Dr. Castor to be extremely thorough in reviewing my file, as well as during my office visit. And he and his assistant provide good follow-up."
