Leslie Edwin

Cushing’s Patient Advocate, President

Cushing’s Support & Research Foundation

Atlanta, GA

Leslie was diagnosed with Cushing’s Disease in 2012 and endured two unsuccessful surgeries including removal of the pituitary gland.  A couple of months after a third surgery to repair a CSRF leak she experienced a spontaneous remission with partially lowered cortisol and some symptom resolution, but recurrence came a few years later and Leslie chose radiation and medication.  Today she manages panhypopituitarism but oddly still does not need daily HC replacement.  Leslie experiences many of the common long-term effects of Cushing’s like exhaustion, joint pain, and executive function impairment. 

During recovery, Leslie sought support and found CSRF online.  After talking with Founder Louise Pace on the phone for two hours, she began volunteering in 2014.  In 2018 Leslie became President when Louise stepped down after actively running CSRF for almost 25 years.

Darlene Shelton

President and Founder

Danny’s Dose Alliance, Dexter, MO

Darlene Shelton and her family created the Danny’s Dose Alliance after her first grandson was unexpectedly diagnosed with severe Hemophilia B and it was discovered that there are protocols that prohibit paramedics and ER doctors from administering patient-carried specialty medications. Realizing the danger, they stepped into action. Starting in Missouri working with the EMS Association, they identified that the problem affects all people with special medical needs and comes from conflicting protocols, fear of liability, and lack of education. These became the 3 main goals: change outdated protocols, create disease-specific treatment guidelines, and educate families on emergency preparedness.

Darlene works closely with several rare and chronic disease organizations as well as state and national EMS Associations. She’s on the Board for Missouri EMS for Children and is participating in the newly developed Pediatric Pandemic and Disaster Preparedness Network established by the Health Resources and Services Administration to remain a constant voice for the people living with specialized emergency care needs.
