Valerie Gerstein, Vice-Chair

While on a study mission to India with Jewish Federations of North America’s National Young Leadership Cabinet, Valerie was introduced to the Gabriel Project Mumbai and immediately felt empowered by Jacob Sztokman’s vision and the work in the slums of Mumbai. Upon returning home her to her family, Valerie’s stories about the slums became her children’s stories and when Liza became interested in helping the children she had heard about and saw in photos, their family’s commitment to GPM deepened and Liza became the GPM Youth Ambassador to the board, Valerie joined her in supporting this mission.

Audrey Trachtman

Audrey Axelrod Trachtman became involved in GPM soon after its inception.  After a career in international strategic planning and finance, she recognized the multiplier effect of a dollar invested in poverty work in the third world.  On a personal level, GPM’s origins as a Jewish charity made the case that much more compelling.

Gladys Delman Teitel 

In January 2014, Gladys traveled to India with her oldest daughter and husband to celebrate her daughter's Bat Mitzvah. While there, they volunteered with GPM as part of the trip and came home inspired by the life changing work that GPM is doing. Since then, Gladys and her husband have travelled to India twice, with two more of their children (they hope to take their youngest son to India as well) on their Bnei Mitzvah trips to volunteer with GPM. Since Gladys' maternal family hails from the Bene Israel Jewish community of Mumbai, these trips have been a very special chance to explore family roots in India with her children. It has also been so meaningful to be involved, even in some small way, with the life changing work that GPM is doing in Kalwa and the villages. Gladys joined the GPM board in 2015 and is now involved with the Youth and Outreach Committee.

Gladys is a graduate of Brandeis University with a BA in Islamic/Middle Eastern Studies and Journalism. She is also a graduate of Touro Law Center.

Lenore Fogel     

Lenore grew up in Atlanta, Georgia and one of her first childhood memories was watching retrospective footage of the civil rights struggles. This began her longing for the world to be a kind place for everyone.  With a BA in psychology from UGA, Lenore earned her MSW from Wurzweiler School of Social Work, with a certificate in Jewish Communal Service. She lived in Israel for five years where she practiced Social Work with vulnerable populations.

While raising her five children in Stamford CT, Lenore focused on different volunteer opportunities in her community. Her husband Ilan is a doctor who spent six months in an AIDS mission in Africa that sparked Lenore’s interest in literacy promotion, leading her to volunteer with SHINE and the Red Cross Children’s Hospital. Currently Lenore coordinates over 100 volunteers in a literacy program at the Stamford Public Elementary Schools with over 100 volunteers and she also works for the Friendship Circle of Stamford, an organization that runs programs for children with special needs and their families. GPM has spoken to her heart since the day “I heard of the wonderful things the organization is doing”.

Scott Miller    

Scott was initially inspired to get involved with the Gabriel Project Mumbai due to its combination of applying Jewish precepts such as Tikkun Olam to areas of dire need together with its incredible and measurable on the ground impact in India. GPM appealed to him as a true practical expression of making the world a better place. Also, after working in the field of Holocaust memory for 30 years he was aware of the historical import and potent power of personal stories, and knew there were inspiring stories in India waiting to be told as well. He sees GPM as a vehicle for bringing these stories to light. 

Scott Miller was a founding staff member at the United States Holocaust Memorial Museum, where he worked for 30 years (1989-2019), and is the co-author (with Sarah Ogilvie) of Refuge Denied – The St. Louis Passengers and the Holocaust.  Scott managed and was spokesperson for the Holocaust Museum’s Rescue the Evidence initiative – the program to build the collection of record on the Holocaust through the acquisition of primary source and original research materials. In this capacity Scott was appointed, in 2001, the Director of the Benjamin and Vladka Meed Registry of Holocaust Survivors – the Holocaust Museum’s names-information and tracing center. In 2006, Scott assumed his latest position as Director of Curatorial Affairs, overseeing the museum’s archival, artifact, photo, film, music and oral history collections. In addition to Refuge Denied – The St. Louis Passengers and the Holocaust, publications include “Teaching About Denial of the Holocaust,” in Journal of Social Education, (Vol. 59, Oct. 1995) and, co-edited with Randolph Braham The Nazis’ Last Victims: The Holocaust in Hungary.

Scott has an MA in Jewish History from the Jewish Theological Seminary, did extensive graduate course work at the Hebrew University of Jerusalem and has a BA in History from Columbia University.  Scott lived in Israel for six years in the 1980s (in Jerusalem, studying at the Hebrew University and teaching at Young Judea Year Course; on Kibbutz Sa’ad as a volunteer; and in the development town Hazor HaGlilit teaching high school English.) In 1982, Scott went to the Soviet Union to visit and bring Hebrew language materials to refusnicks.  Scott also worked for seven summers on the staff of Camp Ramah.

In addition to the gifts of her generous friends, Liza and her sister, Mia donated to GPM following the flooding in Mumbai during the summer of 2017. Liza has a pen pal named Monika in the Ashte Village where GPM operates. They send mail and gifts to each other and often talk live on video calls learning about each other’s lives.
