Patient and Family Advisory Council (PFAC)

The goal of our PFAC is to make care more accessible and understandable for patients and their families.


Our PFAC has given valuable input into countless projects to improve the patient experience, including:

  • Patient education and marketing materials such as brochures, patient letters and new patient packets.
  • Phone system improvements.
  • Enhanced scheduling process for patients, standards for patient communication during appointments and more. 
  • A new visit and annual exam questionnaire.
  • Questionnaire for social determinants of health.
  • Recommendations for patient survey methodology and questions.


The PFAC meets from 5 to 7 p.m. on the first Monday of every month, except in July and August.
We ask for a two-year commitment, if possible.
