Maria F. Perez Sierra, MSN, CNM, is a board-certified nurse midwife with the TPMG Obstetrics & Gynecology’s Innovative Midwifery team. She earned her Bachelor of Science in Nursing from the Pontifical Catholic University of Puerto Rico in Ponce, Puerto Rico. Furthering her education, she received her Master of Science in Nursing – Nurse Midwifery from Frontier Nursing University in Versailles, Kentucky. Maria is a member of the American College of Nurse Midwives (ACNM) and joined TPMG Obstetrics & Gynecology in 2025.

Working as a registered nurse for almost a decade, Maria began her career in hematology and oncology, where she developed strong clinical skills and a deep appreciation for holistic, compassionate care. In 2017, she transitioned into women’s health and began work in Labor and Delivery, where she discovered her true passion for supporting women and families through pregnancy, birth, and postpartum. During her medical training, Maria discovered just how meaningful and impactful women’s health care can be for her community.

As a provider, Maria believes it’s essential to build relationships with her patients through trust and respect. She strives to ensure patients feel genuinely heard and seen, understanding that patients who become active participants in their care can make more informed health decisions and achieve better health outcomes. Maria aims to provide individualized, evidence-based care that honors each patient’s unique values, preferences, and experiences.

Maria sees patients from adolescence to post menopause for pregnancy, birth, and postpartum care. She also offers contraception counseling, family planning, and sexual health education, prevention, and treatment. Maria has a particular interest in group prenatal care and the positive outcomes it provides for women and families. She is a passionate advocate for the model’s push for education and connection among expecting parents, allowing them to receive comprehensive clinical care while also building supportive relationships and learning from one another. Her approach improves maternal satisfaction, increases knowledge and confidence, and often leads to better birth outcomes. Through her work, she continues to explore new ways to improve healthcare access, equity, and overall quality of maternal care.

When she isn’t seeing patients, Maria enjoys reading, spending time with her family, exploring photography, and traveling. Bilingual in both English and Spanish, Maria can connect further with members of her community.

Maria warmly welcomes patients to make an appointment to see her at TPMG Obstetrics & Gynecology.
