He has directed several top performing laboratories throughout the Midwest, which has enabled many couples to realize their dream of having a child.  Dr. Schwartz began working with Dr. Morris in 2012 during the planning stages for the state of the art laboratory at the Naperville Fertility Center.  He and the IVF lab staff ensure quality patient care and pregnancy success are a top priority in all phases of the patient experience at the center.  Dr. Schwartz is active in the laboratory and regularly attends workshops and national meetings to keep the laboratory state of the art.  Dr. Schwartz currently lives in Nebraska with his family and enjoys following Husker athletics.


Jeanine Cieslak Janzen, BA, ELD/TS (ABB), MLT (ASCP)

Jeanine Cieslak Janzen began her career in assisted reproduction over 27 years ago when in vitro fertilization was in its infancy. She obtained a Bachelor of Arts degree from DePaul University in Chicago. She is certified in the disciplines of Embryology and Andrology by the American Board of Bioanalysis. She is also certified by the American Society of Clinical Pathologists in medical laboratory technology.

She has had the privilege of working with pioneers in the field of assisted reproduction such as Dr. Melvin Cohen, “the father of laparoscopy for gynecological disorders” in the U.S.  and Yury Verlinsky, PhD, founder of the Reproductive Genetics Institute and pioneer in the field of preimplantation genetic diagnosis.

Much of Jeanine’s career was at the Reproductive Genetics Institute (RGI) in Chicago, managing the IVF laboratory from 1990 to 2006. While at RGI she worked in the field of preimplantation genetic diagnosis (PGD) and performed over 2000 cases for chromosomal translocations and aneuploidy.  She has coauthored numerous articles and book chapters specifically addressing embryo biopsy procedures and PGD using fluorescent in situ hybridization.

Her vast work experience includes senior embryologist at VA IVF and Andrology in Richmond, Virginia, the IVF laboratory of Colorado Center for Reproductive Medicine in Lone Tree, Colorado and the Frisco Institute of Reproductive Medicine in Frisco, Texas. She is happy to be back in her native state, to be working in the field she loves and to be back with family and friends.

She is a member of American Association of Bioanalysts, American Society Reproductive Medicine, Reproductive Laboratory Technology Professional Group, Preimplantation Genetic Diagnosis International Society and the American Society of Clinical Pathologists.
