Dillon Buchanan is a ranch boy from Montana. His family is friends with the Brenans and, after a rough start, he became good friends with Jonathan Park. His mother and father, Buck and Sara Buchanan, teach him and his sister Bonnie about the Lord and his handywork through their farm life, but Dillon still had trouble holding back his pride.
Dillon is a minor charactor in the Jonathan Park episodes, but he helps strengthen Jonathan's faith. He has only appeared in two episodes, Showdown at Twin Bridges Parts I and II.
