The Brightness Journey
After over a decade of living with undiagnosed endometriosis, Dr. Sarah turned years of pain and dismissal into fuel for positive change. Her journey through misdiagnosis, research, and self-discovery inspired Brightness PHD—a space where others feel empowered, supported, and validated as they learn to own their health.
Dr. Sarah is a public speaker, published author, health educator and researcher, and holistic coach with a Ph.D. in psychology. She provides encouragement, education, and empowerment—with deep empathy and a strong focus on advocacy—to people living with chronic endocrine conditions such as endometriosis.
Dr. Sarah also supports teens as they learn to understand their mental and physical health and gain autonomy over their bodies.
Blending academic expertise with lived experience, Dr. Sarah creates inclusive, research-informed spaces where individuals feel validated, supported, and equipped to speak up for their needs and use self-management strategies to improve their overall health.
Through speaking engagements, peer sessions, and community outreach, she helps others navigate complex health journeys with confidence, clarity, and compassion.
