Do you have your own story of an unsung hero? We'd love to hear it! Record a voice memo and email it to us at myunsunghero@hiddenbrain.org. 

Some guidance:

--Focus on ONE moment that you will never forget. 

--Make sure you're in a quiet, non-echoey room.

--Speak conversationally, like you're talking to a friend.

--Let us know why this person continues to impact your life.

--If your hero were standing front of you today, what would you say? Address them directly.

-- Here are some tips on how to make a great recording on your phone.

Thank you!
