Making a Positive Difference.

The ERC’s website is dedicated to our Senior Advisor, Nancy Petersen, RN and to the memories of Ellen Johnson, Courtney Lee Crismore and Kristi An Rose.

Endometriosis is an often-painful disease affecting an estimated 176 million individuals around the world (WERF). The disease goes beyond age, gender, race and socioeconomic status. Mistakenly stigmatized as merely “painful periods”, endometriosis is far more than just “killer cramps.” The far-reaching impact of the disorder negatively impacts all of society – indeed; staggering costs associated with it soar near an estimated $119 billion annually (EndoCost Consortium, WERF). The ERC has worked tirelessly since 1997 to make a positive difference in the lives of all those affected by endometriosis.

Endometriosis is often mistaken for other diseases, and frequently takes ten or more years to diagnose correctly. You may have Endo if you experience any of these symptoms:

  • Pelvic pain that gets worse after sex or a pelvic exam
  • Chronically heavy or long periods
  • Bowel or urinary disorders associated with periods
  • Painful sexual activity, particularly with penetration
  • Significant lower back pain with menses
  • Allergies, migraines or fatigue that tends to worsen around menses
  • Crippling menstrual pain
  • Catamenial pneumothorax (in lung endometriosis)


A heartfelt thank you to Commander Susan Pierce Richards NP, artist Angie Whitney and the Selah Fun Runners for their incredibly generous efforts to support the redesign of the ERC’s website and technical upgrades. We couldn’t have done it without you!
