Sierra’s Air Raid offense moves the ball by using a “wishbone through the air” philosophy, with the goal in mind to get all 5 skill positions equal touches on game day. Mentoring the offensive line and coordinating the offense is Daniel Diaz-Romero, who enters his seventh year on Ben Noonan’s staff since joining in 2013. The Sierra College Air Raid offense led the state in passing yards and total passing touchdowns in 2015, and ranked third in the country in both statistical categories during that same season. Under Coach Diaz' leadership, year-in and year-out, the Wolverine offense has consistently ranked among northern California's leaders in many statistical categories.
Diaz-Romero grew up in Half Moon Bay and played football at UC Davis in 2003, where he was named a top scholar athlete. He received his BS in Exercise Biology from Davis in 2007 and earned his math and physical education teaching credential at Sac St. in 2009. He has since earned an MS in Kinesiology from the University of Central Missouri as well.
Diaz-Romero coached at Woodland HS (2005-08) and at NorCal powerhouse James Logan HS (2009-2012), where, in 2012, he was named the Logan Coach of the Year. In addition to his Sierra coaching duties, he is a math teacher at Center HS in Antelope.
Dan and his wife Hillary reside in Sacramento.
