She built the thing that was missing.
When Sarah Glynn — a clinically trained midwife and health publisher — was diagnosed with breast cancer, she looked for one trusted place that held everything together: medical guidance, complementary approaches, practical support, people who understood.
It didn't exist.
She had already lost her mother to the same disease. She knew the system was fragmented, and what that fragmentation costs women. So she built what was missing.
Peony is integrative care, grounded in evidence — designed by someone who has stood on both sides of it, as a caretaker and as a patient.
She also wrote The Breast Cancer Book — the guide she couldn't find, written to equip the women who come after her.
Integrative care, grounded in evidence.
