My experiences at Willis College have been life-changing. In completing my program, I grew in many ways. My confidence increased and I was amazed at my own capabilities, which I didn’t recognize until coming to Willis. The atmosphere at Willis made me feel like I belonged to a large family; that we were all in it together to succeed. Hats off to the staff of Willis College because they work together as a team and everyone helps everyone. No one falls through the cracks. Thank you Willis College. Sharon Schwartz Willis College
