About Colleen E Tillema
About the Provider
I grew up in a family of medical professionals, so caring for others has always been part of who I am. As a primary care nurse practitioner, I assist patients with a broad range of medical issues, from new and emerging concerns to chronic disease management. It is a joy to be able to form relationships with my patients, support them through all stages of life, and even care for their whole families.
My approach to care is patient-centered and trauma-informed, rooted in trust and respect. I learned a lot from my time as a sexual assault nurse examiner, and it has deeply shaped the way I practice. My goal is to partner with patients, empowering them to make health care decisions that are not only based on the medical evidence, but fit into their lives and prioritize safety, equity, and their unique needs and goals. I provide safe and affirming LGBTQIA+ health care and am passionate about working with medically underserved populations.
It’s an incredible privilege to learn people’s stories and be part of their lives. Whether the change is big or small, helping someone make progress that truly matters to them is deeply rewarding — and one of the best parts of what I do every day.

She didn’t really care about the fact that I had been dealing with a nagging runny nose and slight cough for 3 weeks. She just said, “there’s a lot of sickness going around”.

Colleen was very attentive and helpful. I felt well supported which is not always the feeling you get in a large hospital system setting. The virtual aspect of being able to meet anytime on screens is very helpful for working adults with busy lives. Her bedside manner even through a screen was very impressive.

I am so excited to join this healthcare team! One visit was beyond 7 1/2 years trying to communicate with the last medical group. She listened, remembered, reviewed and wrapped everything so perfectly and professionally and got 4 things accomplished that my last doctors could not all that time. Night and day difference.
