Meet Jen Willems
MSN, APRN, AGACNP-BC • Sole Provider & Owner
A Journey Rooted in Compassionate Care
With 22 years of healthcare experience, Jen's calling to medicine was solidified during her early days as a nursing assistant in cardiac transplant at the University of Minnesota. There, providing direct patient care during patients' and families' most vulnerable moments confirmed her dedication to nursing and compassionate healthcare.
The majority of Jen's nursing career was spent in high-acuity settings including the ER and cardiac, medical, surgical, and neuro intensive care units. This intensive experience shaped her understanding of both the critical importance of evidence-based practice and the need for personalized, patient-centered care.
Professional Journey
Education & Certification
Jen received her Master's of Nursing from Marquette University in Milwaukee, Wisconsin in 2012 and is a board-certified Adult-Geriatric Acute Care Nurse Practitioner accredited through the ANCC. Her advanced training provides the foundation for comprehensive care across the adult lifespan.
Discovering Integrative Medicine
After starting her family and parenting young children, Jen began working part-time at a local integrative medicine clinic in their infusion room. Initially, the concepts were foreign—especially when compared to how hospitals operate. However, after years of working directly with patients and witnessing long-term chronic illnesses resolve and conditions that "conventional medicine" couldn't help improve, her perspective expanded.
This experience opened her eyes to root-cause medicine and functional approaches as common-sense integrations to conventional practices when appropriate. The dichotomy of research/evidence-based practice and personalized medicine became central themes that Jen carries into her current practice.
Current Expertise
Over the past year, Jen has focused on treating patients with complex conditions including weight and metabolic disorders, thyroid disorders, gut issues, and hormonal dysfunction. Her approach combines her extensive critical care background with integrative medicine principles.

Beyond the Clinic
Family Life
In her free time, Jen enjoys spending time with her husband, four small children, and two dogs in the Northwoods of Wisconsin, where she grew up. This connection to nature and family keeps her grounded and reminds her of what truly matters in life.
Personal Wellness
Jen practices what she preaches when it comes to wellness. She enjoys weighted vest walks with the sunrise, sauna sessions, reading, vintage and antique shopping, and baking. These activities reflect her belief in the importance of movement, mindfulness, and finding joy in simple pleasures.
