About Diane

Diane is currently accepting new patients for Functional Medicine, Menopause/Perimenopause issues, and other hormonal issues. However, she is NOT accepting new fertility patients at this time.

Diane approaches each woman as a unique individual and loves to talk to you as if you were one of her own family. Functional Medicine is her current passion—looking at the root cause of illness and the whole person in relation to external and internal environments.

Diane Dunniway, DNP, APN, WHNP-BC, CFCMC, is a women’s health nurse practitioner. She received her Master’s in Nursing from the University of Illinois at Chicago (UIC) and is credentialed through the National Certification Corporation (NCC). She also completed the Doctor of Nursing Practice through UIC in 2010. During her residency, she focused on menopausal issues as well as fertility care.

Diane is also a Certified Fertility Care Medical Consultant in Creighton Model Fertility Care. If you are still in your childbearing years and struggling with PMS, irregular cycles, infertility, polycystic ovarian disease, desire a true family planning way to monitor your fertility (without contraceptives), or just want to know more about the miracle of your body, this system is specially tailored for you—to meet your needs. Call today and find out more about this program and how it respects the dignity of women and marriage and works with your body’s cycle instead of against it. It might even “S.P.I.C.E” up your marriage (spiritual, physical, intellectual, creative/communicative, and emotional aspects of your relationship). By combining Functional Medicine with Creighton Model Fertility Care, Diane can better help those planning to achieve a pregnancy by balancing hormones and helping to create a truly healthy preconceptual environment. 

Even if you are not currently having any of the issues noted above, you can still see Diane for any other women’s health issue you are facing. She is especially passionate about overall wellness and looking at root causes for maximized health.

Patient Testimonials

I was reluctant to try the telehealth appointments, but oddly enough it was easy to use Zoom, as MyCatholicDoctor has it set for simplicity. I found this to be a very undistracted and unrushed way to communicate with my provider. Anyone looking for help with hormone therapy or needing to simply feel better should schedule an appointment with Diane Dunniway. She has the insight and patience to not only get to the bottom of your health issue, but she works hard to help you maintain and improve your health. I cannot recommend her enough. Not only is she a brilliant health provider – she is empathetic, patient, and understanding. -Jackelyn

I love Diane Dunniway. She changed my life! I love the service. Thank you Diane! -Jovie

MyCatholicDoctor was a great experience. Easy to find a practitioner and easy to schedule. Electronic appointment reminders are wonderful. Logging in to see my practitioner was easy. My provider, Diane Dunniway, is a good listener, very caring, and thorough. Great experience!! -Donetta
