Meet Doctor K.

The dreams we have for our futures exist for a reason. Our commitment to ourselves to follow these dreams determines the quality of our lives. While this journey may not always be easy, I am here to help.

I believe that everyone deserves to have a family. I provide access to top-quality fertility care for all my fertility practice, CNY Fertility.

Through decades of clinical practice, I discovered that infertility (and virtually all other diseases we humans suffer from) are caused primarily by the foods we eat and the frequency at which we consume them.  Similarly, I found that the power of positive thinking can have radical outcomes for your health, wellness, and life goals.

Through the power of positive thinking, changes to diet, and a nurturing attitude toward overall health, you can achieve what you envision and desire most. By showing up for yourself, you have already begun. I’m here to show up for you too.


Founder & Director

Robert J. Kiltz, MD

Dr. Robert Kiltz is the Founder and Director of CNY Fertility, one of the largest and most innovative fertility practices in the country,  with over 60% of its patients traveling from out of state or overseas to be seen.

Over more than two decades of helping families grow, Dr. Kiltz has developed cutting-edge approaches to fertility grounded in Western medicine and supported by practices of holistic medicine. To treat the whole person—mind, body, and spirit, Dr. Kiltz revolutionized the Fertility industry by providing full-service healing arts centers where patients receive massage, acupuncture, and yoga instruction. This patient-centered approach extends to Dr. Kiltz’s commitment to democratizing access to fertility treatments by pricing most fertility treatments at only 1/3 the cost of the national average.

Dr. Kiltz routinely shares his thoughts on diet, wellness, spirituality, and fertility in his blog and via bi-weekly Facebook and YouTube Lives.

A thought leader in the keto carnivore movement, Dr. Kiltz believes that an animal-based diet dramatically improves mental clarity, fertility, and health, empowering people to live their best lives. In addition to his own media channels, Dr. Kiltz appears regularly on numerous popular blogs and social media outlets, and has shared his views as a speaker at TEDx.

Dr. Kiltz is a Diplomat of the American Board of Obstetrics and Gynecology and Fellowship trained and Board Certified in Reproductive Endocrinology and Infertility. A Graduate of the University of Southern California, he completed medical school at the University of California, Davis. After residency at the University of Colorado Health Science Center in Denver, he practiced at Kaiser Permanente in California followed by a fellowship in Reproductive Endocrinology and Infertility at Harbor UCLA Medical Center. Prior to founding CNY Fertilty, Dr. Kiltz practiced reproductive endocrinology and infertility at the Alta Bates In Vitro Fertilization Program while a clinical faculty member at the University California San Francisco, annually ranked among the top two medical schools in America.

Raised in Los Angeles, and now a Central New Yorker by choice, Dr. Kiltz is a licensed pilot, frequently commuting in his Cirrus SR22T between CNY Fertility’s offices in Albany, Syracuse, Rochester, and Buffalo. He makes his home on the beautiful shores of Skaneateles Lake where he draws inspiration from his practices as an accomplished painter and potter.
