Mosaic Integrative Medicine

I’ve had the privilege of walking alongside Dr. Elizabeth Winters for many years—as classmates, colleagues, and fellow advocates for women’s health and fertility. Our paths have crossed in many meaningful ways: we've taken advanced trainings together, attended countless conferences, and collaborated on complex cases. Through it all, I’ve consistently been inspired by her clinical skill, her compassion, and her dedication to her patients. Dr. Winters brings a unique and powerful blend of expertise to her practice as both a naturopathic doctor and a trained midwife. This allows her to offer truly comprehensive, whole-family care—from fertility challenges to pregnancy, postpartum, and beyond. She has extensive experience working with complex infertility cases and brings a thoughtful, root-cause approach that supports the whole person, not just the diagnosis. She goes above and beyond for her patients, offering care that is as grounded in science as it is in empathy. I deeply respect her work and would not hesitate to recommend her to anyone seeking holistic, integrative care on their fertility or family-building journey. Kindly, Dr. Rosia Parrish, ND Naturopathic Wellness Center of Boulder

Can not say enough about what Dr. Winter has done for my health. Having the benefit of a true partner in wellness has been the most exceptional blessing. I have and will continue to recommend her to any friend that is seeking a doctor with a functional approach to medicine. If only all doctors could bring the personalization that she brings, and I look forward to a future where all patients have the benefit of working with doctors like her for both optimization and better outcomes relative to commonplace procedure.

Dr. Catalina is incredible. I had my first consult with her back in December 2021 after I experienced a severe rash/hives breakout all over my body that I could not contribute any cause to. I was not having any success with visits to my primary care or emergency room doctors who simply wanted to throw steroids or a pill at me to mask symptoms. Dr. Catalina worked with me to try and find causation. I cannot tell you how much she has helped me heal over the course of the past few months. She has spent time researching my symptoms and emailing me recommendations in between visits. I highly recommend her to anyone who is looking for a functional medicine doctor that will spend time looking at all possible avenues for what is actually causing your issues. I cannot stress enough that it is imperative to look at causation and address what your body needs to help you heal. It's not an overnight process, but if you are willing to invest the time, and work with someone who can provide a comprehensive treatment plan then I would highly recommend Dr. Catalina. She is a thoughtful and caring doctor who is invested in helping her patients find answers and individual treatments that will truly make a difference in your overall health. I am so glad I found her!!
