In patients' words

"Dr Stone is a great cardiologist and explains everything in detail so we can better understand my husband's heart condition. The only bad thing is that today I have tried to contact both locations Harlingen and Weslaco and no one is answering phones today I guess."

LocalityBiz patient review

"We were very impressed with Dr. Danielle Stone. She was caring, great listener and very informative and very professional. I believe I made the right choice in choosing her as my cardiologist."

South Heart Clinic official website testimonial

"It is both disappointing and frustrating that my mother has called the office a total of six times over the past two days and none of her messages have been returned."
