Rooted in Care. Inspiring Growth

Jen Wittman is a Psych Mental Health Provider at Golden Oak Health

Jennifer Wittman DNP, ARNP, FNP-C, PMHNP-BC

Jennifer is a dual board-certified nurse practitioner in Family Practice and Psychiatric Mental Health. She earned her Doctor of Nursing Practice (DNP) from the University of Iowa in 2019 and her Bachelor of Science in Nursing from Iowa Wesleyan College in 2013.

Jen believes healthcare works best as a team effort. She loves creating a space where patients feel comfortable sharing, asking questions, and making decisions together. Her goal is to help each person feel supported in ways that fit their unique needs.

Outside the clinic, Jen enjoys a full and active life with her husband, their three rescue dogs, and her close-knit family. She values the time she shares with her four sisters and parents, whether it’s a big family gathering or a lively, competitive board game night. Jen also finds balance through painting, staying active on the pickleball court, and cheering for the Iowa Hawkeyes.

She’s a proud, busy mom who embraces the beautiful chaos of family life, always finding joy in the little moments (and a good dose of laughter along the way).
