The Access to Care Committee has the principal mission to assist patients affected by metabolic disease and obesity in 1) obtaining appropriate, safe, and effective medical care, 2) to improve the care and treatment of people with obesity, and 3) to advocate for the health care policy that ensures patient access to high quality prevention and treatment of obesity.


Committee activities include: developing the strategic vision and strategies to make improvement in access to care; advocating for legislative changes on the state and local level that will affect health care coverage; addressing the politics, policies and ethics of access issues on the local, state and national levels; and bringing together initiatives/partners to effectively address access issues.
