Dr. Gebhard has been our family's doctor for over ten years! We started with him in Ladera Ranch and have followed him to his new office in Mission Viejo. He takes his time, sits with you and actually listens, not like those other doctors who just type on their computer and rush out the door... He is truly one of the best!
