Co-Executive Director

Lead Doula Trainer


Juli Tilsner is a California licensed Midwife, Certified Professional Midwife and the Co-Founder & Co-Executive Director of Cornerstone Doula Trainings.


Juli has been attending births ever since the age of 19 when she gave birth to her own daughter at a midwife-directed, experimental birth center within the local hospital in Minneapolis, MN in 1977. It was through her experience of continuity of care, combined with the hands-off nature of the midwifery model that left a long-term impression resulting in her own professional path to midwifery.


Juli’s birth career began with first supporting her friends and peers through their births all through the 1980’s, then became a certified childbirth educator and doula in 1999. During her time as a childbirth educator and practicing doula, Juli concurrently apprenticed at a freestanding birth center in San Francisco until 2003, at which time she passed the NARM board exam and became a Certified Professional Midwife. Juli joined an established Bay Area home birth midwifery practice and worked as a full-time homebirth midwife for 15 years. Cornerstone Doula Trainings was founded by Nickie and Juli in 2006 to meet a great need in their community for midwifery-model centered doula training and mentorship.

Juli currently holds active CPM and California LM midwifery licenses to date and currently provides consulting, montrice and doula support in Portland, OR. 


Juli’s passion, path and practice in the birth world has shown itself to be a continually evolving process of personal, professional and political growth. Coming from challenging beginnings, she considers those challenges to be the gifts that have made her the teacher and mentor she is and continues to be for so many.  Juli has a passion for birth justice and trauma prevention and resolution, and she continues her own work of healing intergenerational trauma for herself and her family in her daily life. She is proud to bring this passion and vision into her work as an activist, healer, educator, leader and mentor. 


In 2010 Juli enrolled in the Pacific Academy of Homeopathy - a modality that she discovered on her own path to self-healing. Because of the transformative and healing experiences she gained through homeopathy, this modality became a focus throughout her midwifery career. Juli is well known in the birth community for her advanced workshops including  “Homeopathy Essentials for Birth Professionals" which will be online and available for purchase soon! 


Currently, Juli lives in Portland, Oregon, where she offers Montrice services and Midwifery-style prenatal and postpartum care. She also offers consultations to birthing people and birth workers, alike. Juli enjoys hiking with her dog Salem, cooking, fermenting, music, beading, and spending time with her family.

OFP,  Movement and Pushing Support Instructor for Oakland Labor & Birth Doula Training

Gingi Allen- owner of The Art of Mothering, Birth Doula & Postpartum Healing Specialist, Certified Professional Midwife, Licensed Midwife. 


My love for midwifery care began about 16years ago after I took my first childbirth education course.  As a fresh undergraduate in Environmental Planning, Sociology & History, I was able to connect my knowledge of healthy environmental practices with the impact that birth health has on the whole of society.  It was after the birth of my first child in 2002 that I saw everything birth and was called to support the mama-baby unit and healing of empowering women & families.


Soon I became an educator, supporting hundreds of families in their choices around a healthy pregnancy, empowered birth, and nourished postpartum, as well as womb wellness.  Along the way, I studied many holistic healing and midwifery techniques and now have integrated them well into my doula & midwifery practice.  During my midwifery schooling and training, I chose to extend my program to get the fullest out of my training (at home birth and birth centers), while raising my two sons as a single mother.  My road in birth work and midwifery was raw, challenging, and beautiful much like the work of being a mother.  It is an honor to support new life into this world and I look forward to developing intimacy, trust, and a deep understanding with the families I support.

Infant Sleep Educator for Portland Postpartum Doula Training

With over 20 years of infant care experience, it wouldn’t be an understatement to say I am passionate about birth, parenting, and all things baby. Working with expanding families during the perinatal year continues to deepen my love for this calling. I am drawn to birth by a deep seated belief that gentle and thoughtful beginnings have the power to heal. I started my higher educational career at Reed College studying sociology with an emphasis on social justice and diversity. So it should come as no surprise that In my spare time I love nerding out to the latest research on pregnancy and keeping up to date on modern and traditional birth practices. I am a certified full spectrum doula supporting families through the whole perinatal continuum. Recently I took the plunge into becoming a certified sleep consultant. I approach sleep coaching from the most compassionate and gentle methods that are tailored to fitting families's individual parenting styles while supporting biological and physiological necessities. In February of 2018,  I welcomed my first child, Maverick, into my family. His presence has been a welcome reminder to slow down and rediscover wonder. I enjoy sewing, traveling and spending time in community.
