Tammy turned her hemophilia A diagnosis into a mission
“We need more research surrounding women and why they bleed the way they do.”
– Tammy lives with hemophilia A and uses Esperoct®
Meet Tammy
“I’ve heard thousands of times over the years that women can’t have hemophilia…I’ve heard every excuse in the book.”
When Tammy was first diagnosed with hemophilia A, she was thought to be one of just 12 girls who had ever been diagnosed in the United States. She often didn’t receive appropriate treatment for her hemophilia and struggled to get doctors to pay attention to her symptoms.
But when she saw how differently her son’s hemophilia was treated, she learned to powerfully advocate for them both.
“My son has never had an issue with not being taken seriously and I’ve had to fight for that every step of the way.”
After a harrowing hospital experience, Tammy made it her mission to step up for herself and for other women living with bleeding disorders. Her journey is inspiring—and if you’re a woman or girl experiencing bleeding symptoms, you may find that you recognize a lot of yourself in her story.
