About Us

Andrea Henderson, LM, CPM, IBCLC (she/her)

Licensed Midwife
Certified Professional Midwife
International Board Certified Lactation Consultant

From a young age, I aspired to become a “doctor who delivers babies”—what many might describe as a calling. Although I did not know what a Midwife was as a child, my fascination with pregnancy, birth, and newborns was always present. This passion guided my academic choices and career decisions.

I began my midwifery education at Central Washington University, where I worked towards a Bachelor of Science in Pre-Midwifery. This degree was uniquely tailored with the help of my advisors to fit my interests and goals. My journey continued at the Seattle Midwifery School, where I earned my certificate in midwifery in 2007.

My commitment to supporting families grew as I became an International Board Certified Lactation Consultant (IBCLC) in 2010, allowing me to provide comprehensive care during the transformative stages of pregnancy, birth, and postpartum, with the specialization of newborn feeding.

I have personally nursed all three of my children, including twins. My experience began with breastfeeding one baby, which provided a foundation for understanding the process. However, when I later breastfed newborn twins, I encountered new challenges and difficulties. These firsthand experiences have given me insight into the potential hurdles that families may face with feeding newborns.

I have genuinely loved my career as a Midwife and Lactation Consultant. Outside of raising my own children and having a family, I have discovered that there is nothing I would rather do than assist families during the miraculous time of pregnancy, birth, and the postpartum period.

I am deeply committed to a holistic model of care, which emphasizes one-on-one support delivered with respect and dignity. My approach centers on building trusting relationships and ensuring that each family feels supported, understood, and empowered throughout their pregnancy, birth, postpartum, and newborn feeding journey.

For as long as I can remember, I have felt drawn to supporting pregnant and postpartum families. The Pacific Northwest is home, though I spent four years in Boise, Idaho, earning my Bachelor of Science in Biology and a minor in Spanish at Boise State University. It was during this time that I began to understand my passion for supporting families during their transition into parenthood. My journey to midwifery continued when I decided to apply to midwifery school. I graduated from Bastyr University and received a Master’s of Science in Midwifery along with an emphasis in Botanical Medicine.

I have had a full-circle experience with Northshore Midwives & Lactation Consulting. I started back in 2017 as a Student-Midwife. In 2020, I became a Birth and Clinic Midwife and attended hundreds of births with the team. My time supporting the practice has evolved over the years and most recently, I entered the role as Administrative Assistant.

Not only am I a member of the team of Northshore Midwives & Lactation Consulting, I most recently had the privilege of being on the receiving end of care, as I gave birth to my daughter in my own home. Outside of supporting the practice, I am spending time with my family in our small house in a little piece of the woods. We spend too much of our time on home improvement projects and finding new trails to hike together. I enjoy anything that keeps me creative and am most recently trying my hand at cut-flower gardening.

Licensed Midwife
Certified Professional Midwife
Registered Nurse
International Board Certified Lactation Consultant

When I was a teenager, I read a book about midwives and immediately knew that someday I would become one myself. That conviction never wavered even as life led me in other directions, including earning a bachelor’s degree in environmental science, working as a botanist all over the U.S. and the world, and experiencing new cultures through travel. During those years, I also attended births as a doula and did volunteer work in human rights and public health.

Eventually, I followed the call to midwifery and graduated with my M.S. in Midwifery from Bastyr University in 2021. Since then, I have worked for several local midwifery practices, including Northshore! I have also worked in Guatemala and Honduras training midwives and advocating for humanized obstetric care, and as a community health nurse locally.

As a midwife, I saw the need for more accessible, family-centered lactation care for my clients. I sought out additional training and experience in lactation, including learning from Andrea here at Northshore, and became an International Board Certified Lactation Consultant (IBCLC) in 2025. I am grateful to be able to provide lactation care with a midwifery approach, supporting families through the transformative and unpredictable journey of feeding their babies.

My goal is to create supportive spaces for families to learn, be vulnerable, and make choices aligned with their values and needs. A special passion of mine is supporting other queer folks on the journey through pregnancy and parenthood. I also speak Spanish fluently and love caring for Spanish-speaking families. I am committed to continuing to educate myself and acknowledging my privilege in an ongoing effort to grow into a better provider and human.

In my time off, you can find me traveling, riding my bicycle, or adventuring in the outdoors.

Kira O'Neil, RN, IBCLC (she/her)

Registered Nurse
International Board Certified Lactation Consultant

For more than 16 years, I have had the privilege of caring for women and babies as a Registered Nurse in Labor & Delivery, Postpartum, and the NICU. Throughout my career, I discovered my greatest passion is supporting families beyond birth through individualized prenatal education, lactation care, and infant feeding support. I believe every family deserves the time, education, and encouragement to feel confident as they navigate pregnancy, feeding, and the early postpartum period.

As both a Registered Nurse and an International Board Certified Lactation Consultant (IBCLC), I have had the honor helping hundreds of families navigate the joys and challenges of feeding their babies. Whether supporting a first latch, working through feeding difficulties, or helping parents gain confidence in caring for their newborn, I am passionate about providing evidence-based guidance while meeting each family where they are.

I am also the mother of four children, and my own experiences have given me a deep appreciation for both the beauty and the vulnerability of the postpartum journey. I understand that feeding a baby is about so much more than nutrition—it is about building confidence, nurturing connection, and helping families feel supported during a season that can feel overwhelming.

My approach is rooted in listening first. Every family has a unique story, and there is no one-size-fits-all solution. I strive to create a welcoming, judgment-free space where parents feel heard, respected, and empowered to make informed decisions that align with their goals and values.

It is an honor to walk alongside families during this special chapter of life, and I look forward to supporting you as you build confidence in feeding your baby and caring for your growing family.

Stephanie LaDuke (she/her)

Postpartum Doula
Holistic Wellness Practitioner

My name is Stephanie LaDuke and I am a Holistic Wellness Practitioner supporting parents in pregnancy, postpartum and beyond. As someone who experienced Postpartum Depression, OCD, and Anxiety (PMADs) I especially enjoy working with those experiencing the baby blues and PMADs as it’s a topic near and dear to me. My care is focused on the wellness of the parents, however that may look for you: from help with the babe(s), preparing food and meals, caring for your pets, and other light household duties. Additionally, as a Certified Wellness Prenatal and Postpartum Movement Instructor I can provide guidance on pelvic health in pregnancy and healing and recovery postpartum. I am also a Certified Wellness and Nutrition Coach, Aromatherapist, and Reiki Master for other support tools. I offer a space to be heard about your new identity as a parent, to share the highs and lows of parenting, and a brave space to be vulnerable and share what’s coming up for you. I have a variety of resources and networks to aid in getting you the support you need and deserve. You’re not meant to do this alone. I look forward to working alongside you on this journey.
