Care Philosophy

This content was provided by Dr. Canales "Growing up listening to his father, an insurance agent, tell the stories of his clients had a profound effect on the kind of physician Dr. John Canales would become. "I like hearing my patients' stories. I think it makes me a better interventionalist because I understand where they're coming from and how my treatments may affect their lives," says Dr. Canales."
