Ms. Muir has more than 25 years of experience in behavioral health care including program administration, managed care, direct patient care and population health management. As a licensed mental health counselor, she has specialized in overseeing emergency mental health services and organizations.

She has extensive subject matter expertise in behavioral health emergency services and oversaw statewide emergency services programs (ESPs) in Massachusetts including strategic planning for 21 ESPs to ensure high quality, culturally competent, clinically and cost-effective integrated community-based behavioral health crisis assessment, intervention, and stabilization services. Her efforts helped establish these ESPs as viable service alternatives to hospital emergency departments.

In that role, she led the organizations’ health care reform implementation efforts. She served as the behavioral health director for the health system’s Medicaid accountable care organization (ACO). She also launched a successful behavioral health community partner program– a community-based entity that works with ACOs and managed care organizations to provide targeted care management and coordination to Medicaid members with significant behavioral health needs, including serious mental illness and addiction.

Previously, Ms. Muir served as the vice president of network management at Massachusetts Behavioral Health Partnership, an organization that manages behavioral health care for more than 500,000 Medicaid members statewide. She directed the development and implementation of network quality, access, and rate and provider performance standards including performance-based incentives and policies and procedures.

Ms. Muir spent 15 years working as a clinician in a variety of settings with a primary focus on crisis intervention. She earned her master’s degree in counseling psychology from Northeastern University and her bachelor’s degree from University of California, Los Angeles.
