Julia Weise

CBA + DITC Consultant

Julia Weise (she/her/hers) manages several Linkage to Care projects, including HIV treatment, PrEP initiation, HIV jail transitions, and cardiovascular patient navigation. With over 25 years of experience at Denver Health and the Denver Prevention Training Center, she loves her diverse and somewhat fragmented role of program manager, clinical supervisor, trainer, and consultant because every day is different and meaningful. A Social Worker by background, Julia’s favorite aspect of her work is relationship building and collaboration with colleagues and (local and national) partners.

When she’s not increasing the capacity of clinical settings to provide outstanding individualized health care services to all or advancing equitable health care delivery, Julia is happiest when the sun is shining, and there is something fun and active to do in the beautiful outdoors of Colorado (summer preferred!)
