A third son is a senior in high school and recently became an Eagle Scout. Dr. Venegas and his wife, Jannette — who has been his medical office administrator for more than 20 years — decided to come to the Valley in search of a family-friendly environment after living in “the big cities” (New York and Miami) for several years.
