Women's Health Nurse Practitioner Board Certified

Anna Geiger (she/her/hers) joins the practice as a board-certified Women’s Health Nurse Practitioner with over ten years of nursing experience.  She completed her undergraduate and graduate studies at the University of Pennsylvania where she earned her master’s degree in women’s health with a minor in oncology.  She spent the last five years as a nurse practitioner in gynecologic medical oncology at Memorial Sloan Kettering Cancer Center in New York City.  Her specialized degrees and prior experience at one of the premier cancer centers in the nation has fostered a passion for oncofertility preservation.

“For patients encountering challenges with reproductive health, especially those with a new cancer diagnosis looking at surgical, medical or radiation therapy on the horizon, I want to be a source of support, empathy and expertise.   Each patient’s circumstance is unique, and ultimately my goal is to help empower them with an understanding of their reproductive health, honor their goals, and to give back a sense of control that often feels lost on these journeys.”

Anna will also support those patients seeking fertility preservation for non-cancer-related indications including elective indications and those seeking gender-affirming hormone use. Furthermore, she will be a part of the team supporting our patients as they travel through their infertility, fertility and/or miscarriage journeys.

She is new to the Midwest so welcome her and don’t forget to tell her about all the cool things STL has to offer!




Professor, OBGYN
Division of Reproductive Endocrinology and Infertility

Dr. Dan Lebovic (he/him/his) completed a Reproductive Endocrinology and Infertility fellowship at the University of California, San Francisco.  He was raised and educated in California, although he has been fortunate enough to enjoy other great towns in the USA throughout his career. After his fellowship, he obtained tenure at the University of Michigan, where he performed NIH-supported research on endometriosis. He then moved to the University of Wisconsin–Madison as the REI Division Chief, where he became full professor and successfully rebuilt their IVF program. He has authored a handbook entitled “Reproductive Endocrinology & Infertility: Handbook for Clinicians” and has contributed chapters to reproductive medicine textbooks as well as Up-To-Date®, a peer-reviewed online publication for physicians. Dr. Lebovic is an Oral Board Examiner with the American Board of Obstetrics and Gynecology. He currently serves on the editorial board for Fertility and Sterility.

As the son of immigrants (including a Holocaust survivor), Dr. Lebovic was raised to value hard work, honesty, and integrity. He strives to be available for any questions that may come up because he firmly believes half the battle is understanding the reasoning behind diagnostic tests as well as the chosen treatment. By gaining a better understanding of what lies ahead, Dr. Lebovic hopes patients can gain more trust and enthusiasm, ultimately leading to a successful outcome.

“It is a huge privilege to assist infertility patients by balancing optimism and hope with realistic expectations (and a tincture of humor) in what can be a very arduous process. The advances in our field give me great hope to pass forward and allow patients to realize their dreams.”


Dr. Kenan Omurtag (he/him/his) is passionate about helping patients build their families.

Everyday is full of new and exciting adventures for a couple or individual embarking on a sometimes short, sometimes long journey. How neat is it to help them navigate that the highs and lows of the process. That bond is unlike any in medicine, in my opinion. And the team of professionals that I work with provide an ideal environment for patients, bar none.


Dr. Valerie Ratts (she/her/hers) loves working to help couples and/or individuals have a child. She takes pride in helping to change and improve the world one small step at a time.

“I love what I do because I work within a team of very talented people including well-trained, bright doctors, dedicated nurses, talented ultrasonographers, cutting-edge laboratory technicians, and understanding staff. We all have the goal in mind to help and support our patients who need the best medical care, compassion and resources.”

Throughout his career, he has directed nine IVF, Andrology/Endocrinology laboratories, and constructed five ART laboratories.

Dr. Ahmady received his Ph.D. in Embryology from the National University of Singapore. His post-graduate research focused on male infertility. He did a systematic study of the fertilization ability of dead sperm (at the cellular and molecular level, especially DNA damage) to unravel the process of life, concluding that the integrity of sperm DNA is the most determining factor. He developed the Single Sperm Curling Test for selecting viable sperm in ICSI procedure. He also developed a hamster ICSI assay for evaluating the fertilization ability of severe male factor patient sperm. He produced the first ICSI live birth in the mouse. Dr. Ahmady is an author of a book and co-author of a chapter in Atlas of Embryology. He has published more than 30 peer-reviewed papers. Several pioneers in the field have quoted his work on DNA damage.

He is a certified High Complexity Lab Director (HCLD) from the American Board of Bioanalysis. He also holds a certificate of qualification as a Lab Director in Andrology and Endocrinology from the New York State Department of Health. He is a member of the American Society for Reproductive Medicine (ASRM), current chair (2022) Regenerative Medicine & Stem Cell Biology Special Interest Group (RMSCBSIG), and a member coding committee.

Our fellows are physicians who have completed a post-graduate residency in obstetrics and gynecology and are pursuing additional, specialized training in reproductive endocrinology and infertility. Fellowship training is essential to our commitment to developing expertise in the next generation of leaders in our field.

Kelsey Anderson, MD

3rd year Fellow

Kelsey (she/her/hers) was born and raised in St. Louis, Missouri.  She left her hometown to obtain her BA at Vanderbilt University and returned to St. Louis to attend Saint Louis University School of Medicine for her medical degree.  Her Reproductive Endocrinology Away Rotation at Washington University made her fall in love with WashU and with REI – she went on to complete her OB/GYN residency at WashU and was overjoyed to be able to stay for fellowship.  Her research interests include subchorionic hemorrhage in IVF pregnancies and investigating factors which impact IVF discontinuation.  Her passion for reproductive endocrinology stems from it being an innovative, progressive and creative field unlike any other.  She enjoys working with patients to help them on their endocrinology or fertility journey, and there is no better team than WashU to share in that journey.  She has great St. Louis pride and, outside of work, she enjoys going to STL sporting events, exploring her new neighborhood University City, and listening to live music.
