Alumni Impact


Positive change. That’s the impact that so many CofC students want to make. And a vast majority of them get the knowledge and skill sets they need at the College – as well as the inspiration – to make that happen. They graduate and take those assets out into the world.

Here is a small sampling of Cougars who have stepped in where they perceived need and are making their mark in substantive and truly important ways. Ultimately, they’re creating a more sustainable world.

Meet our Alumni:

Sarah Koch, ’04 — Art History & Studio Art double major

Sarah Koch is the co-founder and executive director of Development in Gardening (DIG), an international nonprofit using regenerative agriculture as a way of addressing nutrition, food security, climate resilience and livelihood development to assist some of the world’s most vulnerable people. DIG’s directors and staff prioritize communities that are left out of other development opportunities; communities such as the elderly, people living with HIV, the displaced, the physically disabled, young mothers, the ultra-poor and others. The organization’s work directly addresses eight of the 17 U.N. Sustainable Development Goals and its abiding philosophy is that food is a powerful interventional tool for systems change.

Koch has been doing this work for 17 years, and during that time, DIG has partnered with over 50,000 farmers to develop 110 projects across eight African countries. Though the organization has worked in the Caribbean and Central America, its efforts are currently focused on growing its impact in Kenya, Uganda and Senegal.  

“By cultivating the earth in a regenerative way that also provides for nutritional resilience and food security, we can establish a foundation for prosperity and growth for whole communities, over generations. How we steward our planet, feed our communities, and fuel our bodies is of paramount importance for today and for our collective future. Quite frankly, a better world is rooted in food."

Kenyatta "Kenny" Gardner, ’08  Political Science major

When he’s not advising clients, researching cases or actively litigating in the courtroom, Gardner spends part of his time working as a board member and advocate for Turn90 (formerly the Turning Leaf Project). This regionally-based nonprofit helps adult men recently released from incarceration find their footing by developing the skills and mindset needed to function well in society.

Gardner has been a strong community supporter since his days as an undergraduate. While at the College, he founded HELP, a nonprofit that worked to fight poverty and homelessness in the Lowcountry by collecting food, clothing and money and donating that to area shelters. Of his work with Turn90, he says:

“It is fulfilling to serve on Turn90’s board because the work of creating opportunities for success for men recently released from prison is vital for our society.”

Alexa Rosenthal, ’10  Psychology major

Alexa Rosenthal is the co-founder and Chief Ecosystem Organizer of Ecoversity, an e-learning platform and community builder that works to accelerate a regenerative future. In the past 21 months, the organization has graduated 538 students from 37 countries and given scholarships to 58 students with over 60 regenerative projects activated. Ecoversity, the Earth Leadership School, offers courses in regenerative permaculture, herbalism, mushroom cultivation, regenerative urban design, music as medicine and more. Rosenthal and her co-founder Stephen Brooks believe that society must re-educate itself to preserve its place on the planet, and the lessons to be learned come directly from nature itself.

At the organization’s beachfront campus in Costa Rica, Rosenthal, Brooks and their staff are growing a community of permaculture farmers, herbalists, chefs, yogis, builders, and artists. The mission of Ecoversity, Rosenthal says, is to “practice and teach a simpler, regenerative way of living that nourishes the mind, heals the body, celebrates the spirit and honors the Earth.”

“My goal with Ecoversity is to create curriculum that will create a better world, specifically by working with positive psychology, permaculture, sustainability, community and entrepreneurship to give students the skills they need to feel empowered to make positive change.

Ewan Oglethorpe, ’12 — Data Science major

Ewan Oglethorpe went to work for a big tech firm right out of college, but after learning about the impact of the 2015 earthquakes in Nepal, he switched gears. Right away, he traveled to Katmandu and began investigating how he could help. The result of his effort was the creation of Data Friendly Space, a nonprofit, non-governmental organization committed to improving humanitarian responses through better use of data and better data.

Oglethorpe’s organization offers information management and analysis as well as tools and processes to international aid organizations such as the United Nations and the International Federation of the Red Cross. DEEP (Data Entry and Exploration Platform), a proprietary system that Oglethorpe developed, has been used to track the spread of Ebola in Western Africa, and to monitor human rights abuses in Southeast Asia. As Data Friendly Space enters its seventh year, Oglethorpe remains committed to driving the adoption of modern technologies among global responders to help them work more efficiently. The organization now has offices in four countries.

Damien Beri, ’16 — Biology major

Damien Beri is committed to restoring reef ecosystems around the Hawaiian Islands. That’s an enormous job, but he’s developed a novel way to achieve this. He founded The Coral Conservancy, a nonprofit organization that uses a crowd-sourced approach for conserving and restoring various species of coral

Hawaii’s first community-based coral restoration initiative, The Coral Conservancy trains and teaches community members to identify and help restore broken, damaged corals. Part of the organization’s work involves planting new corals and re-affixing broken corals.

“At the Coral Conservancy, we believe that coral reefs are a public resource, and given that, the communities that rely on them should be allowed to take part in their recovery. We recognize that future generations hold the key to this. By providing young citizens with experience and training in the field of coral restoration, we hope they will go on to become future leaders in charge of preserving coral reefs and helping them recover.

Sam Norton, ’16 — Political Science major, M.S. ’21 — Environmental Studies

Sam Norton launched Heron Farms in 2020 with the mission of creating a sustainable agricultural system and restoring global marshlands by using the earth’s most abundant resource – seawater. Based in Charleston, S.C., Heron Farms operates the world’s first indoor saltwater vertical farm.

Norton and his farm staff grow and market Salicornia, also known as sea beans. These resilient plants are native to the coastal marshes of South Carolina and Georgia (as well as elsewhere). They’re crunchy and salty and are rapidly becoming a staple ingredient for restaurants, which use them as a garnish and a plant-based salt substitute. Norton discovered the potential of raising sea beans commercially while conducting research for his master’s degree in environmental science. He has since expanded his company’s work to include reseeding Salicornia in areas of dredge spoils and consulting on marsh restoration in Bangladesh.

“I grew up eating these things that we called sea pickles,” Norton says of Salicornia. “But I’ve since realized the huge potential in these plants. They can be grown in salt water, which helps put less strain on fresh water supplies, and they can help reduce the salinity in our marshes because they store salt. Consequently, one of our missions at Heron Farms is to restore one square foot of marshland – by planting Salicornia – for every pound of sea beans we sell.

Lauren Shipley, ’17 — International Studies major

Lauren Shipley is the co-founder and executive director of Artisan Global, a nonprofit that develops sustainable jobs, strategies and workspaces alongside international artisan businesses in post-conflict regions. Currently, the organization’s efforts are focused on developing creative industries with entrepreneurs in Northern Uganda. In Gulu, Northern Uganda, Shipley and her cohort have established Artisan Center, a new, shared creative space that functions as an accelerator for young entrepreneurs and artisan businesses. Here, individuals are busy creating in photography, art, fashion design and product design.

Shipley describes her organization’s impact as building long-term solutions with communities facing cycles of extreme poverty in a post-conflict setting. Through a multi-dimensional approach, Artisan Global supports entrepreneurs in the region who are transforming their respective communities. The organization helps launch careers by offering industry training, creative workshops, mentoring and business consulting. Artisan Global acts as a catalyst by covering costs for sewing machines, new materials and other resources that allow for these small businesses to expand in Uganda and internationally.

Jose Chiriboga, ’18 — Computer Information Systems major

Jose Chiriboga is the founder and proprietor of REMU Apparel, a company that operates in his home country of Ecuador, pays a living wage to workers who manufacture apparel primarily from repurposed fabric. (The company’s motto is “upcycle, empower, explore.”) Chiriboga’s motivation for establishing the company grew out of his recognition regarding the egregious waste he saw in the fashion industry. He also sought to create a company that would operate sustainably regarding worker compensation and thereby begin to address the exploitation of laborers that is so prevalent in this industry as well.

“ In the U.S. alone, the average person discards 82 pounds of textiles each year. They’re not just throwing away that material, but all of the energy required to produce it as well. That includes all the electricity, all the water all the raw material. That’s where I see a massive opportunity for change.”

Mikel Hannah-Harding, ’19  — Meteorology and Physics double major

Mikel Hannah-Harding was one of the College’s first graduates to major in meteorology. He went on to secure a job as a weekend meteorologist and multi-media journalist for WRDW News 12/WAGT NBC 26 in Augusta, Georgia, and has become popular in those roles. When he’s not presenting the weather or compiling information for his forecasts, he spends time supporting his community. His popularity means that Hannah-Harding is readily welcomed into local schools.

This year, Hannah-Harding set a goal for himself to make a positive impact on youth, both locally and in his hometown – Beaufort, S.C. Recent outings have involved speaking to second, third and fourth graders at Riverview Charter School in Beaufort, and similar classes at North Aiken Elementary School in Aiken, SC.

“ Speaking to those students, I focused on the duties of a meteorologist, how we do our job, and talked about severe weather, the differences between watches and warnings as well as some of the best methods to stay safe when it comes to lightning, tornadoes, tropical systems, along with other severe weather phenomena. I also aim to encourage and inspire students to pursue their dreams no matter what background they come from.“

Abbie Kline, ’20 — International Studies and Communication double major

Abbie Kline is the marketing and events coordinator for an active nonprofit in Greenville, S.C., called Loaves and Fishes Greenville. This organization sources excess and discarded food stuffs from restaurants, groceries and bakeries, etc., and delivers those items on a daily basis to soup kitchens, food banks and other distributors that support neighbors in need Greenville County. In 2021, the organization rescued and distributed over 2.4 million pounds of food – a service it has been providing since 1991. 

Kline sought out this position because of her personal commitment to making a difference in the lives of those less fortunate. As a student in the Honors College, she volunteered for four years with Charleston’s Green Heart Project. And for her 2020 commencement ceremony, she was invited to speak as the recipient of the Alexander Chambliss Connelley Award, which annually recognizes the student who made the most unselfish contributions to community and campus. In her brief remarks, Kline urged her fellow classmates to do good.

“My hope is that we aim to do good things, as opposed to striving for great, because good is in much shorter supply.”
