I'm still alive thanks to Dr. Jeffery. she spotted a serious issue more than a decade ago. it resulted in life-saving stents and robotic bypass surgery. i thought all was well until she stopped me about 30 seconds into a stress test. beyond her incredible competence, she actually cares about her patients. i never leave an appointment feeling like she looked at me like i'm another paycheck. trust is earned and i trust Dr. Jeffery with my life.
