Adrianne Naddell

Adrianne Naddell studied Occupational Education and Health Care Administration at Wayland Baptist University and completed the Genetics Assistant training program through the Johns Hopkins School of Medicine. 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 brings compassion, diligence, and attention to detail in her work with Advocate Genetics, understanding the critical importance of this work in helping 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.”

"As a prior fertility patient and embryo donor myself, I feel I engage with patients with 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."
