Patient Reviews
Feb 15, 2024
First heart attack, went to ED. I had a horrible experience with another cardiologist at the ER and for the follow up. Dr. JOHNSTON was referred to me by my daughter’s law firm and although the drive was a bit far from my home, it was well worth it! He was so genuine, he listened. He explained and made sure I understood, he was very polite and shook my hand to my surprise. I’ve heard nothing but good things from his staff, and it wasn’t just because they work for him. I observed their mannerisms and their body language. They were being honest. I need this doctor because nowadays you’re just another person , but he didn’t make me feel that way. He made me feel like he was really concerned about my well-being. Advised me the steps we need to take to get better. I saw him later in another part of the building, and he greeted me with such kindness as he did at my appointment…awesome!
