2011 Fall Provider Symposium

On November 18, Healthfirst hosted its third Provider Symposium at our new 100 Church St. headquarters. These special bi-annual symposiums, spearheaded by Healthfirst’s Dr. Susan Beane, have become staple events that allow providers to share ideas about best practices and improving patient care. Approximately 100 provider partners were in attendance to learn about integrating healthcare and planning systems to improve health outcomes.

Providers in attendance also had an opportunity to fill out a survey about their communication preferences, and pick up educational materials from Healthfirst Healthy Living, the American Diabetes Association, and more. The next symposium will be held in spring 2012.
