  • I have been to heart specialists in several states. There is no one like Stephanie Coulter anywhere! Her "spot-on" diagnosis, connections to the best doctors in any field, and ability to have them by your side immediately is unbelievable! She views you as a cohesive whole and understands the linking of symptoms between various organs. She has guided my complicated medical incidences with precision and kindness with spectacular results! I consider her my brilliant doctor and caring friend!

  • Outstanding doctor, saved my wife's life after she went into cardiogenic shock. Very dedicated to her patients and explains things well. We had a cardio doctor in Pasadena, but I just didn't feel comfortable with his hospital, not him. I decided that if anything happened to my wife it would happen at the medical center. I wanted a doctor that specialized in the female heart and after reading reviews, we ended up at the Texas Heart Institute and Dr. Coulter.
