We're here for you – every day of the year!

Established in 1985, Bennett Fertility Institute is associated with one of the most experienced private gynecology and obstetrics practices in the state of Oklahoma. The program director, David Kallenberger, M.D., has more than 40 years of extensive experience in the medical and surgical treatment of infertility. The institute's senior physician, Eli Reshef, M.D., is a board-certified reproductive endocrinologist, with more than 30 years of experience in the field.

Bennett Fertility is CAP-certified, and regularly passes a rigorous clinical laboratory inspection. The clinic is an original member of the Society for Assisted Reproductive Technology (SART).

Our nurses, some of them former infertility patients, have extensive experience in managing the complexities of fertility treatments and offer sensitive and compassionate care.

Our clinic is staffed every day of the year, including weekends and holidays, by a physician, a nurse, and a laboratory technician.
