Hannah Llorin, MS, CGC, is a certified genetic counselor and researcher. She is currently the Director of Genetic Counseling at the Atria Health and Research Institute in Manhattan, NY. Her work focuses on the clinical integration of genomic medicine into primary care, with a focus on technical and clinical strategies that enable genetics to inform routine healthcare decision-making. As a GC-FIRST Research Fellow at University of Minnesota, Ms. Llorin studies the clinical and experiential outcomes of pharmacogenomics service delivery models.
Ms. Llorin previously served as a primary care genetic counselor with LMND Medical Group, where she oversaw the development of a telegenetics service and developed a structured genetics training program for internal and family medicine physicians. Earlier in her career at Brigham and Women’s Hospital in Boston, she specialized in reproductive genetics, counseling patients on prenatal screening and diagnostic testing for fetal anomalies, pregnancy loss, and single-gene disorders.
Ms. Llorin's scholarly work examines the ethical, social, and clinical dimensions of genetic testing in reproductive endocrinology, obstetrics, and primary care. Her work frequently explores the limitations of traditional genetics in diverse populations using implementation science frameworks and qualitative methods.
In addition to her clinical and research roles, Llorin is actively involved in professional service and education. She serves on the advisory board for Stanford University’s MS Program in Human Genetics and Genetic Counseling, has served as executive editor for the National Society of Genetic Counselors’ Perspectives in Genetic Counseling, and contributes to national initiatives focused on inclusive genetic counseling practices. She received her Master of Science and Bachelor of Science from Stanford University.

Ms. Llorin’s research interests include the clinical implementation of genomic medicine in preventive and primary care settings, including direct to consumer genetic testing, population genomic screening, and pharmacogenomics. She is particularly interested in evaluating the clinical utility of genetic information in routine (primary) care. She also studies the ethical and social implications of preimplantation and prenatal genetic screening. Her work further explores inclusive genetic counseling practices, with a focus on improving genetics care for LGBTQIA+ individuals.
The selected publications collectively represent work focused on the clinical implementation of genetic testing. Each paper addresses a practical gap between emerging genomic technologies and real-world implementation, and position genetic counselors as a bridge between molecular diagnosis and precision prevention (in primary care) or treatment (in prenatal care).
