Amy loves doing investigations because she is curious, fearless about asking questions and tends to see all sides of things.
Amy is a leading expert in the field of workplace investigations. She has more than 40 years of experience in employment law, as an attorney, investigator, arbitrator, mediator and trainer. She has worked with and for a large range of employers and employees – public and private, large and small – throughout the country. She is also a retired administrative law judge.
Her areas of expertise include preventing workplace harassment and responding to allegations of harassment, investigating workplace harassment, discrimination, retaliation, whistleblower claims, diversity in the workplace, how unconscious bias impacts decision-making and other forms of workplace misconduct. Amy frequently does public speaking on these issues.
Amy has investigated hundreds of workplace complaints, including complaints against elected officials, CEOs, founders of startups and board members. She has testified as an expert witness more than 70 times and also as a fact witness regarding her own investigations. She has trained public and private employers in how to investigate workplace complaints, sexual harassment prevention and implicit bias.
Amy led the founding of the Association of Workplace Investigators (AWI), helped develop the association’s curriculum and served as its Chair for several years. In 2022, Amy was a Fulbright Fellow in Cape Town, South Africa, where she trained lawyers and HR professionals in workplace investigations and anti-harassment practices.
Amy’s first love is the theater. Now that she has had a long and happy career in the law, she has gone back to it – doing solo performing and improv classes. She also loves to travel, especially to places that feel very different from the United States.
