Ora R. Fox was a cofounder of Sigma Engineering in 1997. We were saddened by his passing in late February, 2008. Ora was a fabulous engineer, gifted business man, loving husband, devoted friend, and wise mentor. Sigma Engineering owes its success to Ora's vision and hard work. He will be greatly missed.
