Make the change that will change a life.
We'll be with you every step of the way.

Learn About Leadership

Start by learning what it means to be an effective leader. All Global Interns get access to our award-winning online leadership course as well an accomplished mentor associated with the Global Internship Program. From PR and Marketing executives, to Founders of publicly traded companies, we are very proud to connect students with a remarkable list of mentors!

Complete Your Global Challenge

How will you impact the world? We will guide you step-by-step as you come up with a manageable project that will make a global impact. We need help on numerous existing projects, but we encourage creativity. With the help of your mentor, you will be able to engage your community and bring about positive change in the world. We give you the tools, you make the change.


Once you finish your global challenge, we will give you the opportunity to come on a “vision trip” with us to travel and see the impact you made firsthand. Additionally, we will give you access to the Global Internship network and will write you a letter of recommendation, both of which will be helpful for whatever you decide to do. Take these tools and go change the world!


“H4O helped me to stand out. Everyone I knew in High School was involved in some club or program, but H4O actually teaches you about leadership and gives you a tangible opportunity to lead. I’m glad I took advantage of it!”
