A native Arizonan, Mark Bool was born and raised in Tucson. Mark graduated from the University of Arizona in 1981. He has a daughter, Jenny and son-in-law, Sean, who has become a favorite hunting partner.

Quite a bit of  Mark's  hunting background involves archery.  He shot on staff for PSE for almost 12 years.  In 1991 Mark and his family moved from Tucson to where they now live in Phoenix. 

Mark is active in many of the state conservation organizations including President of the Arizona Deer Association in 2004. He continues to serve on the ADA board today.

Mark began working with Yellowhorn Outfitters in 2000. 

He has a strong commitment to not only guiding successful hunts, but also doing everything he can to ensure the hunt experience is memorable and enjoyable for each hunter.    

The highlight of Mark’s hunting career was his own desert sheep hunt in 1999.  Mark took a beautiful ram in Arizona's Eagletail Mountains.
