“Zebra Crossings has given my children a power they never would have learned to unleash. Here, they feel accepted, encouraged and understood. They are taught that what they believe to be their inadequacies, can really be the fire that burns inside of them and makes them a stronger, more courageous, and joyous person. Truly, Zebra Crossings has changed our lives for the better.”

- Thaia Katsos

“It is an amazing experience to not feel alone in the world. To meet and share some wonderful kid stories has given me and my family so much hope for the future”

- Family Camp Parent

“I am not sure there are many places where there are such kind, caring people.  It is also a place where others have chronic illnesses, some the same as yours.  It makes it a lot of fun to just talk and relate to someone that you can’t necessarily do at school.”

- Teen participant

“Before camp my son was embarrassed to go to the nurse. He wouldn’t take meds before gym, and then tried to hide his asthma symptoms and chest/lung pain.” Since camp, my son has been willing to take albuterol before gym class, has been more confident and willing to participate in groups with active outdoor activities.”

- Asthma Camp Parent

“Zebra Crossings is a fun place where you can go and feel safe because they understand how you feel. You get to express yourself and experience all kinds of things and nothing holds you back.”

- Luke, age 10
