“I’m a husband, and a father, and my family means everything to me. Helping you grow your family in the safe, responsible, and personal way I believe in is incredibly fulfilling to me.”

Welcome From Ronald F. Feinberg, MD, PhD, Chief Medical Officer & Director of IVF Programs

Welcome to RADfertility. I look forward to talking with you personally, but in the meantime, let me share a bit of my history with you.

With a lifelong interest in the sciences, I was drawn to reproductive medicine primarily because of the research it involves. But the human side of infertility—the personal, real-life side—soon won my heart as I began to work with more and more couples in their quest to have the families they wanted.

I’m a husband and a father, and my family means everything to me. So to be able to help you grow your family—in the safe, responsible and personal way I believe in—is incredibly fulfilling for me. My partnership with Dr. McGuirk makes it even more so. We share a philosophy of care that I know benefits every family we work with.

For over two decades, I’ve had the privilege to work directly with the academic medical community (including many years at Penn and Yale) as well as national patient advocate groups such as RESOLVE, the American Infertility Association, the PCOS Association and PCOStrategies.

"I feel so lucky to have found RADfertility. I tried two other clinics before I expanded my search and found RADfertility. I drive an hour each way to go to them but I don’t regret a thing. They are so caring and so professional. Every time I message them they respond quickly. Every time I see them they have a friendly smile and warm welcome. They explain everything so well and I never feel lost in the process as I did elsewhere. They also took the time to figure out what was wrong. Other clinics threw up their hands, said 'I don’t know' and pushed me to try IVF."



"Dr. Feinberg and the entire staff at RADfertility are absolutely amazing. The receptionists, coordinators, nurses, and lab staff are compassionate, caring, and straight forward. I’ve had a 12-year infertility journey and I’ve tried other clinics but RADfertility was the only one I felt at ease with. They answered any questions that I had and were there any time I needed them. My coordinator, Amy, was the absolute best and always had my back. Dr. Feinberg’s dedication to his patients is incredible. You are not just a number there, you are a person with individualized needs and care."

"My journey with RADfertility and Dr. McGuirk started when my husband and I were trying to conceive and were having difficulty. We went to RADfertility, where we met Dr. McGuirk. I always say she changed my life and 'fixed' me. Dr. McGuirk is always learning more about endometriosis and how to help her patients. She’s brilliant and truly cares for you! I’m eternally grateful to her and everyone at RADfertility for their unwavering support, love, and care."

"I cannot begin to explain how wonderful RADfertility is. We were frustrated with trying to start a family and it not working for us. The entire team of doctors and nurses made us feel comfortable and hopeful that we would be parents. We experienced so many ups and downs but we never felt like we were on our IVF journey alone, we had our RADfertility team every step of the way. If you're looking for a supportive team on the IVF journey, look no further. RADfertility is the absolute best."
