The concept should be about protecting the crown, which means taking your mental health seriously to prevent suicide and live healthy happy lives in honor of Zak. 
Maybe display a crown (which symbolizes the head/brain) being elevated
Please use an abstract, unique design that will translate well on t-shirts and letterhead for business purposes. 
I am open to color choice but, please incorporate the color green (the mental health color), white and/or gray

My experience with mmyousuf was exceptional. This logo design has tremendous meaning to me and I appreciate all of the diligence, cooperation and patience in perfecting it.  This artist was a good listener and truly captured the essence of my concept. Thank you.
