About the Doctors

Robert Greene, MD


I served as the Medical Director of the Sher Institute for Reproductive Medicine (SIRM) Northern California based in Sacramento until 2011 when I briefly relocated to CNY Fertility Center before joining one of the premier centers–Conceptions Reproductive Associates of Colorado. I am a board certified OB/GYN and reproductive endocrinologist whose practice focuses on the diagnosis and management of fertility problems. My special interest is correcting underlying problems associated with hormone imbalance and optimizing success rates for couples trying to conceive through integrated diet/lifestyle recommendations as well as modern high tech options.

My wife and were frustrated when we underwent fertility treatment. As a result of my unique experience, I have taken a variety of steps to help educate my colleagues, interested patients, their friends and family as well as journalists of the latest research. Enhancing Fertility (formerly The Greene Guide) is an extension of that effort to provide access and understanding to the most recent findings. Most important, the information is practical.

I frequently reach out through the media including a featured guest spot on NBC’s Dateline and ABC News, and appearances on Oprah and Friends with Dr. Mehmet Oz and participate in several magazines and publications including Self, Glamour, Cosmopolitan, Conceive, Pregnancy, Fit Pregnancy, Shape, iParenting and Ok! Magazine. I am also the author of several books including Perfect Hormone Balance for Fertility, Perfect Hormone Balance for Pregnancy, Perfect Balance and the Happy Baby, Healthy Mom Pregnancy Journal.

I hope you find these efforts useful and empowering. Please let me know if you have any thoughts or suggestions.

I am very excited to be part of the fertility team at Conceptions Reproductive Associates! I’m thrilled to be joining this blog and for the opportunity to write about my personal interest of optimizing fertility using lifestyle changes.

Dr. Greene has a loyal following with his blog. I plan to stay true to his original blog style and hope to share with you all my enthusiasm for enhancing our fertility. My blog posts are meant to inform and will be my personal opinion. I hope to share with you my interpretation of the existing evidence and provide the same type of advice I would share in a conversation with a close friend or family member.

I first became interested in the impact of the environment on our health because of research that I conducted at Washington University in St Louis, where I found that exposure to a handful of common chemicals in our environment was associated with earlier menopause. At the University of Colorado, I received several grants to support further studies of how exposure to plastics can change the way our ovaries work and can impact the development of early pregnancies. I also serve on an advisory board for agencies that help advocate for reproductive health, such as the Agency for Toxic Substances and Disease Registry and Pediatric Environmental Health Specialty Unit.

As a physician mom, I understand how challenging the process of trying to conceive can be. In my free time, I love going on adventures in the mountains with my family, gourmet cooking, and distance running.

I look forward to your feedback on our new & improved website! I would also love to find out specific topics that you are interested in learning more about. I want to make this blog YOUR go-to source for enhancing fertility.
