Genetic Counselor

Gina Davis, MS, LCGC

Gina Davis is a multi-state licensed, board-certified genetic counselor, who specializes in the field of reproductive medicine (infertility, assisted reproductive technologies and pre-implantation genetic diagnosis).

She served as a genetic counselor at the University of California, San Francisco's Center for Reproductive Health from 2004 to 2013. While studying to become a genetic counselor, Gina served as a medical assistant at two private fertility practices in Southern California, and conducted research at a UC Irvine molecular genetics lab. She has been immersed in the field of reproductive medicine her entire career, and brings a wealth of knowledge in working with both practitioners and patients.

Gina has helped to shape the role of the genetic counselor within the field of Reproductive Medicine. She has assisted in the training of fellow genetic counselors, physicians, nurses, other health care practitioners and undergraduate students in reproductive genetics through lectures, small group facilitation and mentoring. She has given numerous presentations at professional and patient support meetings, and has been co-author of diverse publications within the field. Gina is the past chair and current member of the Genetic Counseling Special Interest Group of the American Society of Reproductive Medicine (ASRM).

She is an active member of the Assisted Reproductive Technology Special Interest Group of the National Society of Genetic Counselors (NSGC), a member of the Pacific Coast Reproductive Society and the Society for Ethics in Egg Donation and Surrogacy. She has also worked as a volunteer with Resolve and the March of Dimes. She serves as genetic counselor and previously served as the medical science liaison for PacGenomics, a clinical genetics laboratory specializing in single cell technologies. She is also a member of the Medical Advisory Committee of Reprotech Ltd., the leading cryobank specializing in long-term storage of reproductive tissue.

"As a fertility patient myself, I feel I engage with patients with a greater compassion and appreciation of the emotional complexity of reproductive medicine. I understand that given the rapid advances in genetics and reproductive medicine, it is becoming increasingly difficult for patients and physicians alike to gather this information on their own and make deliberate and conscientious use of it. My practice is dedicated to addressing the unique questions and concerns of each patient or couple, to help them make educated decisions about their options.

I chose to start my own practice because I feel that many fertility patients are underserved by the current model of genetic counseling. I feel that fertility patients deserve genetic counseling that is specialized for reproductive medicine, and that the service should be accessible, wherever they are seeking treatment." 

Adrianne Naddell

Office Manager

Adrianne Naddell studied Occupational Education and Health Care Administration at Wayland Baptist University. A tenacious learner, she put herself through college while working full-time as a manager in wholesale, even with multiple moves as a military spouse. She and her husband were challenged by infertility and were eventually able to have their children through IVF. She found it a great privilege to spend her childrens' infant and toddler years at home with them, and pursued an opportunity to work with children with special needs when her children went to school. She is happy now to assist those who, like her, have experienced difficulty with fertility and long to be parents. She is excited to make Advocate Genetics her home, and help people create their own precious families.

“Having been through the process of trying to conceive through IUI and IVF, I feel a strong empathy for those in similar situations. As a patient myself, I believe such experience is of great importance when working with families going through the emotional roller coaster of reproductive medicine.”
