About Thrive Theory

  • Welcome! I'm Katie – your friendly neighborhood expert in lactation and infant feeding. I am an International Board-Certified Lactation Consultant (IBCLC), experienced maternal-child health Registered Nurse (RN), and the proud owner of Thrive Theory Lactation and Infant Feeding. For the last decade, I've been on a mission to guide families through the exciting journey of new parenthood through home visits, virtual sessions, problem-focused care and anticipatory guidance. Whatever you need, I’ve got you covered!

    While I'm great at solving feeding hiccups, what really excites me is preventing them in the first place! It's about giving you the knowledge and tools to feed your baby and parent with confidence. But when problems do arise, rest assured that I don’t just address the surface issues— I dive deep to uncover the root causes and help you get back on track.

  • Katie Cohen is an IBCLC and RN with a BSN from Drexel University in Philadelphia, PA. While living and studying in Philadelphia, she gained experience working at The University of Pennsylvania (UPenn) Student Health in Women's Health, the Hospital of the University of Pennsylvania (HUP), and The Children's Hospital of Philadelphia (CHOP) in the operating room, specializing in Ear Nose and Throat (ENT).

    Katie has been serving families in Tucson since 2014. She is a strong believer in the power of relationship-based preventive healthcare, and she has worked with several award-winning preventive health programs as a Public Health Nurse in Pima County such as Nurse-Family Partnership, and as the Pediatric Nurse Team Lead on the Tohono O’odham Nation. She was the recipient of the Tohono O’odham Nation First Things First Champion for Young Children Award.

    Before founding her own lactation practice, she was a Lead Lactation Consultant at a Femtech start-up and collective of IBCLCs dedicated to expanding access to breastfeeding support through telemedicine. Katie is passionate about facilitating breastfeeding and infant feeding education for both new parents and her fellow lactation professionals alike, and currently serves as the Professional Development Coordinator for the United States Lactation Consultant Association (USLCA).

  • Thrive Theory is the evidence-based philosophy at the heart of everything I do as a nurse and lactation consultant.

    It's simple: when families thrive, so do their little ones. I'm here to understand your unique needs and work together to craft customized, sustainable feeding plans. Whether it's direct breastfeeding, bottle feeding, pumping, or any combination of feeding strategies, we'll navigate the journey together with open conversations, trust, and absolutely no judgment.

    Rest assured, I'm not about one-size-fits-all solutions. Thrive Theory is all about getting to the true root causes of any feeding challenges that you encounter, and embracing what works for your family. Ready to embark on this adventure? I'm here to support you through the highs, lows, and everything in between. Let's work together to create a story of thriving wellness for you and your family!
