Welcome From Adrienne B. Neithardt, MD, Director of Donor Services

I am very proud to be a member of the physician team at RADfertility. Drs. McGuirk, Feinberg, and Schillings share the same commitments I make to my patients: to find the underlying cause of their infertility and to provide them with the best outcome possible. I believe we achieve this goal at RAD by combining state-of-the-art surgical and reproductive technologies with compassion and care.

As a young medical student, I was awed the first time I witnessed the birth of a baby and intrigued by the nuances behind reproductive science. From then on, I decided to dedicate my career to women’s health. As I struggled to start a family of my own, I realized that I wanted to help others on their own journeys to start a family. There has been nothing more rewarding than watching the joy people have when their dream to expand their family is close to realization.

As a board certified Reproductive Endocrinologist and Infertility (REI) specialist, I have had opportunities to participate in multiple facets of research, and have enjoyed years of working in private practice. This specialty has provided me the opportunity to work in all areas of male and female infertility and reproductive endocrinology. My experience allows me to help women with ovulatory disorders successfully perform IVF, and perform minimally invasive surgery when necessary. As the Director of Donor Services at RAD, I have a special interest in helping patients who wish to build their families utilizing donor eggs, sperm, embryos or using a gestational carrier.

I look forward to meeting you and helping your dream of having a family become a reality.

"We had a wonderful experience working with RADfertility. Our doctor was so sweet, informative and helpful with all of our questions. The front desk, it’s always nice to be greeted by a friendly smiling face."



"RAD heard my hopes, dreams, and wishes and led me toward them while holding my hand. My dream came true. I was guided to a beautiful baby girl! It took less than a year for my pregnancy to begin and it was successful. This was the best decision I ever made. Thank you, RAD!"

"From the beginning our team was determined to find a way for my husband and I to complete our family. All the RAD staff was knowledgeable and truly cared for us. We wish we could have continued with them after our baby hit 12 weeks. We thank them daily in our prayers for giving us our beautiful baby girl!"



"We will be forever grateful for the wonderful care we received at RAD! Dr. Feinberg took the time to listen and create a plan we were comfortable with. The whole team was amazing and truly care about their patients. You have exceeded our expectations. Thank you!!"

"Dr. Neithardt was amazing. She explained in great detail all the options we had and put us at ease about the entire process. Everyone has been amazing and I have absolutely no complaints. Today I am 17 weeks pregnant and we only have Dr. Neithardt and her wonderful team at RAD to thank."

"They are the most amazing team of doctors and care coordinators. After having started at another facility I was so happy to come to RAD. They are truly amazing, never make you feel like just a number and have empathy and compassion every step of the way. They also get the job done! Thanks RAD!"

"Dr. McGuirk is a very holistic doctor. She doesn’t just treat the fertility issues. She also points out personal health ideas (juicing, whole 30) to help heal/treat the whole patient. She is honest and open. Be open minded and trust in her process. This is a marathon, not a sprint! Dr. McGuirk will be with you the whole way."

"I will never be able to put into words how thankful we are for RAD. Rhonda was there every step of the way as we were going through the process. Everyone was so welcoming and patient as we asked questions. We were blessed with a daughter, who is now three. I have already recommended and will continue to recommend RAD to people who need help growing their family!"
