Marybec Griffin, PhD

Co-Creator

I’m @marybecgriffin, co-founder of @drperiodhackers. I’m a sexual health researcher, trained doula and certified sexologist.

I’ve got a passion for all things bloody - periods, vampires & slasher films. Bodies that bleed but don’t die are uncanny and awesome!

Bethany Samuelson Bannow, MD, MCR

I’m Bethany, a hematologist who is passionate about equal care and representation for menstruating folks with bleeding and clotting disorders.

I see patients, do research and advocate for improvements in the field, my #1 motivation for @drperiodhackers!
