About Us
The Pep Talk Diaries was founded on a simple but urgent insight: girls need early, clear, and accessible puberty education.
When local resources fall short and school programs are scheduled too late, parents are left searching for guidance while girls are already asking big questions.
The Pep Talk Diaries was created as our response. We brought together a nurse, an educator, a marketing expert, a coach, and a writer to design a curriculum that parents can trust and girls can understand.
What began as support for a small friend group quickly grew into something more. As we worked with families, we recognized that while girls needed accurate information, mothers needed space, language, and confidence of their own. Puberty often reopens questions women once navigated quietly, and sometimes alone.
Today, The Pep Talk Diaries equips girls with knowledge they can trust, empowers parents as primary guides, and offers coaching for women who want thoughtful support as they continue to grow through every stage of life.
