Meet Our Founders

Co-founderSally is an Adult Nurse Practitioner and Certified Functional Medicine Practitioner with a passion for understanding the underlying factors contributing to chronic and complex health concerns. Known by her patients as a true medical detective, Sally combines clinical expertise with curiosity and compassion to help patients better understand their health.
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.”
