Elizabeth Nillen combines more than 15 years of employment law background, her recent experience as an ICU nurse, and knowledge as a health care lawyer to investigate employment claims for various health care companies. Beth also handles day-to-day legal affairs for her clients, representing them in all facets of the employment relationship in addition to their health care law-related concerns.

Beth has first-hand clinical understanding of health care through her eight years of in-hospital experience at Honor Health’s Osborn Medical Center, where she began as a Diplomat volunteer in the Emergency Department and then became a stroke-certified Registered Nurse. She worked several units throughout the hospital system as an RN, including the Intensive Care Unit (ICU) and the Neuro, Trauma, and Orthopedics Unit. Beth’s focus was working with patients who suffered from neurological deficits, stroke, and catastrophic and traumatic brain injuries. During the pandemic, she worked on the front lines in the ICU treating COVID-19 patients. Beth also served on Honor Health’s hospital ethics committee as well as recently completed two terms on the Arizona State Board of Nursing’s Scope of Practice Committee.

In 2020, Beth founded a private practice that became a unique one-stop-shop for health care facilities to resolve their healthcare, employment, and legal concerns. She is also a certificate holder through the Association of Workplace Investigators and is the co-founder of the AWI Arizona Local Circle. Through her vast experiences, Beth brings a rare combination of real-world knowledge that allows her clients to achieve their legal goals in the health care industry.
