Specialty Obstetrics of San Diego was founded in 2010 with a singular mission: to provide exceptional, compassionate Maternal-Fetal Medicine care to patients throughout San Diego County. What began as a commitment to high-risk pregnancy care has grown into a collaborative practice led by four board-certified Maternal-Fetal Medicine physicians, supported by exceptional sonographers and a dedicated administrative team. Together, our team is committed to delivering personalized, evidence-based care while ensuring a seamless and supportive patient experience. As our practice continues to evolve, we took an important step forward in June 2025 by relocating our office closer to Sharp Mary Birch Hospital, strengthening coordination of care and continuity for our patients. While our practice has grown and our location has changed, our commitment to serving our patients with expertise, compassion, and partnership remains unchanged.
Our vision is to provide exceptional Maternal-Fetal Medicine care grounded in compassion, trust, and clinical excellence. We believe our patients are more than patients — they are individuals and families navigating some of life’s most important and vulnerable moments.
We are committed to delivering personalized, evidence-based care while fostering meaningful relationships and collaborative partnerships with referring providers. Through empathy, expertise, and seamless co-management, we strive to support the best possible outcomes for both mother and baby and to be a trusted partner throughout every stage of the pregnancy journey.
Our care team is dedicated to providing a welcoming, efficient, and supportive experience for every patient throughout their pregnancy.
