I have a deep love for educating everyone about the power of the birthing body, with the hopes of restoring our culture's confidence in the ability to bring babies into the world calmly and safely. I approach every pregnancy and birth with an open mind and a full heart because every birth teaches me something new. 

Above all else, I value autonomy, love, and support: a birthing person’s right to their autonomy, always leaving space for love between the birthing person, their birth partner, and their baby, and supporting the birthing person and their team for all-around empowering experiences.

Renata Rosa (doula)


My name is Renata Rosa. I am originally from Brazil and I have been blessed to live in the USA since 2005. In addition to speaking English, I also have the privilege of speaking Portuguese. I fell in love with births and postpartum care in 2010, when I provided support to my friend in the birth and postpartum care of her first child. But it wasn’t until 2013, when I had my son and a amazing support from my doula, that I understood the impact of that kind of support for a family in such an important moment of their life. I officially became a birth and postpartum doula in January of 2017, receiving training through DONA.I strive to be a warm and supportive presence as parents create a birth they will always remember. I am comfortable and experienced with whatever birthing environment you choose to have. When I am not doulaing, I absolutely love spending time with my family and learning new things.
