Sustainable systems integration begins with strong, lasting partnerships. Building these connections requires intentionality and planning from everyone involved. When partnerships are built upon a foundation of trust, they are better able to navigate the ups and downs of cross-sector work. Developing and maintaining partnerships can be challenging at times, but meaningful progress happens when you successfully develop relationships across health care, public health, education, social services, and the community that share your commitment to supporting AYA health and well-being.
