In this talk I discuss the problem of accounting for light neutrino masses in theories with dynamical electroweak symmetry breaking. I will first describe this problem generally in a class of extended technicolor (ETC) models, describing the full set of Dirac and Majorana masses that arise in such theories. I will then present an explicit model exhibiting a combination of suppressed Dirac masses and a seesaw involving dynamically generated condensates of standard-model singlet, ETC-nonsinglet fermions. Because of the suppression of the Dirac neutrino mass terms, a seesaw yielding realistic neutrino masses does not require superheavy Majorana masses; indeed, the Majorana masses are typically much smaller than the largest ETC scale.
