Our Leadership - Hodgkin's International

Board of Directors

We began as a group of former cancer patients looking for answers.

Founded in 2016, Hodgkin’s International was born out of the need for connection, support, and reliable information. Co-founders Erin Cummings and Dolly Griffin, along with many dedicated and determined Hodgkin’s survivors, were in search of a solution to some unusual medical problems occurring years after treatment. Our regular doctors were often befuddled and did not know how to help us. We were forced to find answers within our Hodgkin’s community, sharing our experiences, and often learning what to expect from each other instead of our clinicians. Hodgkin’s International was established so that we could do better than that. We came together to provide our fellow survivors with up-to-date news about what we now understand to be late effects. Most importantly, we came together to provide a welcoming and compassionate home for survivors of Hodgkin lymphoma.

ERIN GEDDIS CUMMINGS, MSW, LCSW

Mark Haseloff

Diagnosed with stage 4 Hodgkin’s lymphoma at 17, I’ve carried a deep sense of purpose ever since to improve the lives of others facing cancer. Over the years, I’ve been actively involved in Canteen and Youth Cancer advocacy at both state and national levels across Australia. Through my work with Canteen, I’ve had the privilege of traveling the world to speak about the importance of youth cancer support, and I remain deeply passionate about the AYA (adolescent and young adult) cancer space.

Today, I continue to serve as a consumer representative on various advisory groups—ranging from health system committees to research grants and academic publications. I hold a special interest in survivorship, with a focus on fertility, late effects, and the long-term challenges people face after treatment.

Cancer has taken a lot from me—but it has given me so much more in terms of purpose and perspective in life.

Susan Leigh, BSN, RN-retired

After receiving her degree in nursing from the University of Arizona in Tucson in 1969, Susan Leigh served as a Lieutenant in the U.S. Army Nurse Corps. Seven months after completing a tour of duty in the Mekong Delta in South Vietnam, she was diagnosed with Hodgkin lymphoma and treated with some of the earliest forms of chemotherapy and radiation. This experience influenced her decision to enter the newly founded field of oncology nursing and began this phase of her career working as a research nurse in the new Department of Hematology/Oncology at the University of Arizona Medical Center.

For the past 35 years, Susan has focused her efforts on national advocacy work with special emphasis on the long-term and late effects of cancer treatment. Her most cherished involvement has been with the National Coalition for Cancer Survivorship (NCCS) as a founding member and past president. She has also been actively involved with many professional organizations, including the Oncology Nursing Society and the National Cancer Institute.

Susan also worked as a Survivorship consultant and educator with Arizona Oncology, a multi-site community practice in Tucson, until multiple treatment-related cardiac complications made it difficult to fulfill work obligations and accelerated her decision to retire.

Lauren Seides Chartan, Esq.

I have been shaped by my cancer survivorship since the age of 17. My experience of surviving the challenges engendered by facing life threatening illness, have served to form the foundation for the adult Woman, Mother, and Lawyer I have become and remain faithful to.

As an accomplished, experienced litigator who, after practicing law as both a Criminal Defense attorney in Manhattan, and then a Deputy County Attorney, I returned to Law School to pursue a Masters degree in Family Law (LL.M) degree, while raising my then 8 year old daughter, as a single mom. I feel the fortitude and determination that has helped guide me emanates from the life lessons dealing with multiple cancer diagnosis have given to me. We are so much more than our medical charts reveal.

I share a beautiful home and life with my life partner, David, who will be the first person to say that he has only known me as a survivor, after we met while attending the University of Rochester, where I transferred after being treated for Hodgkin’s lymphoma.
