Co-founderSally is an Adult Nurse Practitioner and a Certified Functional Medicine Practitioner with a passion for getting to the root cause of illness. Known by her patients as a true medical detective, Sally combines clinical expertise with curiosity and compassion to uncover the hidden drivers behind chronic symptoms.
She discovered Functional Medicine in 2009 after reading Dr. Mark Hyman’s The UltraMind Solution. “Dr. Hyman described everything I was trying to do within the conventional model,” she recalls. “The book came at a time when I was feeling disenchanted with medicine and had even considered leaving the field altogether. It gave me hope that we could change the way we practice.”
