Kirk started ZATO, his PPC micro-agency in 2011, was named the 4th Most Influential PPCer in the world by PPCSurvey.com in 2026, and is known for his international conference sessions on Shopping Ads / PMax campaigns and his TEDx talk: Redefining Business Success (Stop the Scale).

Kirk has authored two books, Ponderings of a PPC Professional and Stop the Scale (Building a Digital Agency You Actually Like) and is working (ever so slowly) on building his YouTube channel: Merchant Center Mastery focused on Google Merchant Center tips and mastery.

Kirk currently resides in Billings, MT with his wife, 6 children, road bikes, LEGO sets, 2004 AMG G55, Taylor guitars, books, and probably not as much sleep as he should be getting.
