Staff and Volunteers

Marlene Portnoy
Co-Founder/Executive Director

Marlene Portnoy co-founded DTRF because of the frustration she experienced with the lack of information available and the lack of research on this rare disease. Her husband, Steve, was diagnosed in August 2004 with a retroperitoneal desmoid and has since been treated with surgery and radiation. 

After graduating magna cum laude from Albany State University in 1981, Marlene pursued a career in sales, which she started at Corning Glass Works from 1982-1985 in Chicago, Illinois. She then moved to New York and worked for Playskool Toys, a division of Hasbro Toys, first as a sales representative and then as a District Sales Manager for the Middle Atlantic territory from 1986-1993. She then took time out to raise her two young children and became active in community service which has included activities such as running various social action programs, participating in the local soup kitchen, and working on golf outings and walk-a-thons for local community interests.

Marlene enjoys such active pursuits as running, hiking, biking and skiing. She has a passion for travel and experiencing other cultures.  Marlene’s big bucket list items are finding a cure for desmoid tumors and going to Mt. Everest! 

She resides in Hoboken, New Jersey, with her husband Steve. Marlene has two beautiful daughters, Brittany and Danielle, two wonderful sons-in-law, Adam and Mike, and adorable twin grandsons, Grant and Mason.  All take an active interest in the Foundation.

Jeanne Whiting

In 2005, Jeanne Whiting and Marlene Portnoy founded The Desmoid Tumor Research Foundation to facilitate and fund desmoid tumor research and support patients with access to information. Jeanne’s personal journey with a retroperitoneal desmoid tumor involved resection, recurrence, 2 1/2 years of two different chemotherapies and eventual loss of her right kidney. She is keenly aware of the needs of the desmoid community, and is dedicated to accelerating the search for a cure.

Prior to co-founding DTRF, Jeanne spent most of her career as an attorney. After attending University of Michigan Law School and J. Reuben Clark Law School, she received a Juris Doctor degree, magna cum laude, in 1980. She then clerked for the Michigan Court of Appeals in Detroit, Michigan, and in succeeding years practiced with Sidley & Austin in Cairo, Egypt and in Washington, D.C.; with Shearman & Sterling in New York, New York; with Stern, Dubrow & Marcus in Maplewood, NJ; and, as a sole practitioner.

After retiring from the practice of law to raise her family, Jeanne became involved in various nonprofit organizations, including serving as Northeast Director for Choice Humanitarian (1997-1998) and Executive Director of FamilyCares (2000). She feels that getting a desmoid tumor was both a wake-up call and a calling to a new endeavor as it became clear to her as a patient that this was a field that needed jumpstarting into a new level of accelerated research to develop new treatments.

Jeanne resides in Salt Lake City, Utah with her husband Steve. They raised four sons and a daughter, and now enjoy their seven beautiful grandchildren.

Lynne Hernandez
Director of Special Events & Operations

Lynne’s life officially began on January 1, 2010 at 12:01am, just after she shot the starting gun for her first race. Since then, she has consulted on/timed/directed over 50 running events for local nonprofits. She initially learned about desmoids through running buddy, Sera Snyder, who was diagnosed with the disease and founded Running for Answers 5K in 2010. Lynne has been directing the 5K since 2002.

Although Lynne’s work experience spans many sectors/ industries (federal gov’t, retail, dotcom, large nonprofit, small nonprofit, small business), they pale in comparison to the depth and satisfaction she receives through her work with DTRF.

Lynne lives in Philadelphia, PA, the home of DTRF’s Annual Patient Meeting and RFA 5K.
