Jessica Giordano, MS, CGC

Genetic Counseling
Accepting New Patients
Profile Headshot


My clinical care and research are dedicated to the delivery of accurate, timely, and well-informed prenatal genetic diagnoses in a personalized and value-driven manner for all patients. Working with women, couples, and families facing complex medical decisions due to genetic risk and diagnoses is an honor and I am passionate about ensuring all patients have access to the option for low risk, timely, and accurate genomic diagnoses to better inform decision making about pregnancy management and improve outcomes.

Jessica Giordano, a New York native, completed her undergraduate degree in Biology at Boston College and her Master of Science in Human Genetics/Genetic Counseling at Sarah Lawrence College, graduating in 2008. After graduation, Jessica worked in the public hospital system in the Bronx providing reproductive genetic counseling to patients at Jacobi Medical Center and North Central Bronx Hospital. She subsequently worked at Weill Cornell in reproductive genetic counseling for four years before joining Columbia's Department of Ob/Gyn in 2014.

Jessica is an ABGC board-certified genetic counselor with a passion for reproductive genomic medicine, working in clinical, research, and industry-related settings.

In her clinical work, she has witnessed how non-invasive aneuploidy screening, diagnostic testing via microarray, and pan-ethnic screening has transformed prenatal practice, making complex genetics test part of primary obstetrical practice. Recently, she successfully led Columbia’s fetal exome sequencing study published in Lancet, the stillbirth exome study published in the New England Journal of Medicine, and is the primary manager for the NICHD multi-center study PrenatalSEQ, aiming to study the use of genomic sequencing in pregnancy to change post-natal management. In these research roles, she consents patients, curates variants, and assesses genotype-phenotype correlations with the goal of ultimately communicating results to patients to impact decision-making and clinical management.

Additionally, Jessica has been integral to the recent development and launch of Columbia’s Genetic Counseling Graduate Program and currently serves as a course director and scholarly projector mentor to their graduate students.
