    Every experience that American business woman Leigh-Ann Buchanan remembers has come from travel. Her early trips to the countries in Asia, Africa and the Americas were no small thing — they assisted her to make connections with community organizations abroad, build leadership skills and find a greater purpose in her voluntary work. All of these experiences played an important part in her becoming a mentor (导师) to high school students in Miami, US.

She saw that many of her students from underserved communities had never left the country. This not only shut them out from having life-changing experiences, but they often missed out on college scholarships (奖学金) because their resumes (简历) couldn’t compete with those from higher-income backgrounds.

Then she saw a program founded by her friend in Ghana. It offered US students the opportunity to experience cultural exchanges abroad. Buchanan wondered why the kids she mentors in Miami couldn’t have these life-changing experiences. So, she started the Nyah Project in 2014.

Since then, the project has provided money for 10-day leadership trips to 57 high-performing high school students throughout underserved communities in Miami. All 57 have gotten into colleges around the country, and over 90 percent have received full scholarships to college. Nyah fellows have traveled to countries including Indonesia, Namibia, Costa Rica and South Africa.

The trips bring cultural exchange opportunities, like learning about traditional Balinese dance in Indonesia and teaching younger students in Namibia. Kemoni Alexander, who is studying at Ohio Wesleyan University, was a Nyah fellow in 2017, and traveled to Namibia and South Africa for her first time out of the country.

“The neighborhood that I grew up in wasn’t the most resourceful and my schools were short of money,” Alexander said. “I could hardly believe that I was able to have that opportunity because other people saw that potential (潜力) in me and believed in me.”
