bryan nurnberger, president and founder


Bryan Nurnberger founded Simply Smiles, Inc. in 2003.

Bryan graduated from the University of Colorado in 1999 with a B.A. in history. In the few years after college and before founding Simply Smiles, Bryan worked as a mountain climbing guide, hiked the entire Appalachian Trail, lived with monks in Greece, and worked with sugar cane cutters in the Dominican Republic.

In 2013, he was given the Lakota name "Cante Waste Wicasa", which means "Kind Hearted Man."

Bryan lives with his wife, Kristen, and their dog Chip in Southport, CT.

Fun fact: Bryan is an avid, life-long Star Wars fan. He still has his childhood Star Wars pillowcase from when the first movie was released. It's not old, just vintage.

zachary gross, senior program manager


Zach graduated from Fairfield University in 2012 with a B.A. in Spanish and a triple minor in English, environmental studies, and Latin American & Caribbean studies. His first volunteer experience with Simply Smiles was in Oaxaca, Mexico as a high school student; he then returned to Mexico as an intern during his summers in college.

Since joining Simply Smiles full time in 2012, Zach has - among other things - learned how to test fecal samples for intestinal parasites, earned his bus driver's license, and dressed up as Santa Claus for our annual Christmas party on the Cheyenne River Reservation.

"Fun" fact: Zach inexplicably gets called Josh more times than he can count. He would very much like to know why.

Sam graduated from Saint Michael’s College in 2012 with a degree in history and global studies, and a minor in Spanish. She started volunteering in high school with Simply Smiles in Mexico, and then continued to intern in Oaxaca throughout her summers of college.

Sam became part of the Simply Smiles staff in 2012, and now coordinates and recruits volunteer groups for both our Oaxaca and Reservation programs. 

Fun fact: Sam formed a 3-on-3 basketball team in the summer of 2013 along with her coworkers Bryan and Dave. They only play while on the Reservation, and they only compete against volunteers. Their record is 82-1. (Please do not ask about the 1.)

gaby chavez hernandez, program manager • oaxaca, mexico

In 2002, at the age of 12, Gaby chose to leave her home in a remote Mexican village to pursue her education. In 2015 she received her B.A. in Business Administration from Sacred Heart University in Connecticut on a Simply Smiles Scholarship. After seven years of living in the United States, Gaby made another monumentous decision: to return to Mexico to manage Simply Smiles programs in Oaxaca.

Gaby is an exceptional individual and an inspiration to the thousands of people with whom she's crossed paths in Mexico, the United States, and beyond.

Fun facts: Gaby is the only person we've ever met who owns no music at all. Not one song. She also makes the most ridiculously amazing guacamole you've ever tasted.

marcella gilbert, program manager • cheyenne river reservation


Marcella comes from the Lakota/Dakota/Nakota nation and resides on the Cheyenne River Indian Reservation in South Dakota, where her relatives live and many of her ancestors are buried. She has always had a passion for fresh nutritious food, which led her to earn a Master of Science in Nutrition from South Dakota State University.

Marcella coordinates Simply Smiles' food, garden, and healthy living initiatives on the Reservation; she focuses on educating her people about healthy eating, as well as the re-introduction and protection of wild native foods.

Marcella has been blessed with three children, one grandchild, and an always-loving husband, Phillip.

Fun fact: Marcella also has a passion for dancing at powwows in Indian country. She has danced the fancy shawl style since she was a child (in the "tiny tot" category) and continues to compete, even as she enters the golden age category.

jasmine martier, program manager


Jasmine received her B.A in Applied Anthropology from Bloomsburg University in 2017. Academically, her interests ranged from child development to evolutionary theory. Jasmine spent two summers as a Simply Smiles intern on the Cheyenne River Reservation before joining the team full time in the fall of 2017. She is continuously amazed by the wonderful people, culture, and kiddos both on the Reservation and in Oaxaca, Mexico.

Fun fact: Jasmine enjoys learning about the revolution of punk rock through memoirs and oral history narratives. Patti Smith is her hero.
