A Golden attorney and expert in medical ethics has agreed to hand over her law license for two years after helping a doctor friend acquire Ambien and lying to detectives about it. Susan Fox, a sole practitioner and lawyer here since 1987, will lose her license on Dec. 11 under the terms of an agreement between Fox and state disciplinary authorities. In addition to her law degree, Fox has a master’s in bioethics, a subject she has taught at Regis University, according to an online biography.
