Jennifer Stein (birth assistant)


Hi! My name is Jennifer Stein. I'm the proud mother of 3 incredible daughters and I have them to thank for my passion for all things birth. Specifically, supporting, educating and advocating for women and their families.

It was not until my first pregnancy that I discovered the importance of women supporting women. Being a doula since 2015, I would like to share my experience to support you and your partner during your birth journey. It is important to me to understand what your vision is for your birth day. It would be my honor to support you on your journey.

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.       

Olga Proskuryakova (doula)


I am Olga. I am 34 years old. I am a birth and postpartum doula. I took other different trainings like Childbirth Education, Breastfeeding, Midwife assistant, Rebozo techniques and Spinning babies which I am a big fan of. My aim is that every mother feels grounded, nourished, empowered and ready to take on motherhood! I make sure that each woman that works with me is receiving physical and mental care both before and after birth, evidence based knowledge to make informed decisions, and one of one support from me during this transitional time in a professional non-biased way. I myself have experienced both a medicated hospital birth and an unmedicated home birth with Natural BirthWorks. I know what it feels like to be pregnant, and to have the anxiety and fear of the unknown take over. I know the concerns about how to care for the life of a newborn child and how this new addition may change a family dynamic. I know the desire to want to be a perfect mother, and the fear of not knowing everything and wondering how I will ever learn it all. I understand all of these concerns, which are absolutely valid- and I want to take the weight of these worries off of your shoulders so that you are not going through this fragile time alone. I do different kinds of birth- homebirth, in birth centers and hospitals; experienced in different types of births (vaginal, cesarean, and vaginal after previous C-section) and familiar with many unexpected situations in births. And I love to bring my knowledge into my practice from different cultures: american, mexican, russian, middle east.
