Meet the Executive Leadership Team at AHCCCS

The Arizona Health Care Cost Containment System, AHCCCS, serves nearly 30 percent of Arizonans who are eligible for Medicaid and Children’s Health Insurance Program health care services. AHCCCS is the largest insurer in Arizona, covering half the births, and two-thirds of the nursing facility days, in the state. At the helm of this $14 billion state agency is an executive management team that collectively brings several decades of health care expertise ranging from private sector, managed care, and provider level in all areas of health care management.

On International Women’s Day 2021, the AHCCCS Executive Management team shares their personal “whys” of working in public service health care.

Jami Snyder, AHCCCS director, was appointed by Governor Doug Ducey on January 5, 2019 after having served as the agency’s deputy director since December 2017. With more than 20 years of public and private sector experience in the health and human services industries, Ms. Snyder’s areas of expertise include regulatory oversight, policymaking, and leadership development. Prior to joining AHCCCS, Ms. Snyder served as Medicaid Director for the state of Texas, managing a program covering 4.7 million enrollees at a cost of $29 billion. She has held posts as Chief Operating Officer of the University of Arizona Health Plans, as Operations Administrator at AHCCCS, and as Bureau Chief at the Arizona Department of Health Services.

I truly cannot imagine a more fulfilling role-allowing me to work with an incredibly talented team to supply access to health care to over 2 million Arizonans. The work can be challenging at times, but on a daily basis I am reminded of how we make a difference-for the healthcare delivery system, for communities, and for families and individuals across the state of Arizona”

AHCCCS’ influence on the healthcare marketplace in Arizona is significant and the work my colleagues and I do truly makes a difference in peoples’ lives.  That’s why I’ve remained committed to this agency, its mission, and public service in Arizona.”
