Care Philosophy

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.

I had a regular check up with Dr. Canales last week. The staff was prompt and the doctor and chief nurse saw me right away. Dr. Canales has been my cardiologist since I was in the hospital in June 1916. His diagnosis care in the hospital is why I continued to see him. Additionally, I have recommended several people to him. Frank Parker

Dr. Canales, is just an amazing Dr. He is so in tuned into what is going on with his patients. He sets you straight on what needs to be done. And leads you to greater health. I would highly recommend Dr. Canales, to any one that has a heart problem. I trust him with my husbands heart and I'm a wife, that is very picky with Dr.'s. I'm very greatfull that he and his staff and other Dr.'s that he realize on, helped my husband. Thank you Dr. Canales, for all you do.

Dr Canales has a great attitude towards his patients. He treats his patients as he would treat a family member. I totally wish I had gone to him the first time he was recommended. He is professional and explains thoroughly what procedures he uses and what is expected of you.

Dr Canales make you feel important and listen's to what you have to say. He also explains the procedures so one can understand. I've already recommended him to my friends.

I have found a cardiologist who listens, takes the time to explain what is needed to be done to get you feeling better and then asks if you have any questions. The staff are courteous and return calls and if a delay occurs in seeing you they let you know right away. One day the air conditioning was really cold and when they saw me step out of the exam room into the hall they brought me a blanket .
Our practice and cardiologists aim to deliver the highest quality patient care. We love to hear about these positive experiences. Thanks for sharing this feedback with us!
