About
Kassie Bollig had a seat in medical school before she had a high school diploma. The University of Missouri School of Medicine admitted her through the Bryant Scholars Program, which pre-selects outstanding high school students. She finished a double major in biological sciences and Spanish at the top of her class at Missouri, took her MD and her obstetrics and gynecology residency at the same medical school, then went to the University of Pennsylvania for a reproductive endocrinology and infertility fellowship — and stayed on to earn a Master of Science in Clinical Epidemiology.
That second degree is what makes her research profile unusual for a clinic physician. Her self-described expertise is large database management, prospective cohort development, and advanced statistical and predictive modeling. Her published interests follow from it: biomarkers that detect pregnancy location and viability earlier, hCG algorithms that predict whether a pregnancy will continue, preconception maternal cardiovascular health and ART outcomes, and markers of ovarian reserve and fertility preservation in Turner syndrome.
She also operates. RMA lists minimally invasive reproductive surgery among her areas of expertise, which puts her in the smaller group of reproductive endocrinologists who can address pathology and run the cycle rather than referring the surgical half away. She grew up on a cattle farm in the Midwest and considered a career as a painter before medicine.
Clinical Expertise
- Reproductive endocrinology and infertility: infertility workup, stimulation design, and ART cycle management as RMA’s treating reproductive endocrinologist
- Minimally invasive reproductive surgery: laparoscopic and hysteroscopic treatment of uterine and pelvic pathology that blocks conception, with the recovery advantage that matters when a cycle is scheduled
- Fertility preservation in Turner syndrome: her stated research line, covering ovarian reserve markers and preservation strategy in a population that often loses ovarian function early
- Diminished ovarian reserve: the clinical counterpart to that research — deciding how much time is actually available and when to bank
- Pregnancy location and viability after transfer: biomarker and hCG-curve work directed at pregnancies of unknown location, biochemical pregnancies, and ectopic risk
- Preconception cardiovascular health: a separate research program on how maternal cardiovascular status relates to ART outcomes
Why Choose Dr. Kassie Bollig
She can do the surgery and the cycle. Most reproductive endocrinologists prescribe stimulation and perform transfers, and hand operative findings to a surgeon. For a patient with fibroids, adhesions, a septum or an endometrioma, the sequence question — operate first, or retrieve first — gets decided by one physician who is competent on both sides of it, instead of negotiated between two.
Her research targets the most anxious window in treatment. Whether a pregnancy is in the right place, whether it is progressing, what a rising-but-slow hCG curve means, what to do after a biochemical loss. These are her actual research topics, with published methodology behind them, not patient-education topics she has an opinion about.
A fellowship-era award from reproductive surgeons. At the 2021 ASRM Scientific Congress she received the Society of Reproductive Surgeons In-Training Award for Research — recognition from the surgical society in reproductive medicine, for research, while still in training. It corroborates the surgical side of her profile rather than merely listing it.
She was awarded for the whole residency, not one dimension. The 2020 William T. Griffin Scholar Award at Missouri goes to the resident judged outstanding overall; she also took Outstanding Resident Academic Achievement in each of 2017, 2018, 2019 and 2020, plus the 2016 American Medical Women’s Association Glasgow-Rubin Certificate of Commendation and Holt Leadership and Service Award.
Turner syndrome is a small, time-sensitive population. 45,X and its mosaic forms carry a high risk of premature ovarian insufficiency, and the preservation window can close in the teens or twenties. Few general fertility practices see these patients regularly; she has made ovarian reserve markers in Turner syndrome a named research focus.
Professional Affiliations
Fellow of the American College of Obstetricians and Gynecologists (FACOG). Training: University of Missouri School of Medicine (MD, residency in obstetrics and gynecology), University of Pennsylvania (fellowship in reproductive endocrinology and infertility, plus MS in Clinical Epidemiology). Her academic recognitions cluster in training, including the 2021 Society of Reproductive Surgeons In-Training Award for Research presented at the ASRM Scientific Congress.
Suitable For
- Turner syndrome or inherited premature ovarian insufficiency: the population where the timing of egg or embryo banking is the entire clinical question, and where her research is directly applicable
- Diminished reserve with a preservation deadline: family history, surgical plans, or test results that suggest the window is narrowing
- Biochemical pregnancy or pregnancy of unknown location: patients who have tested positive and then could not be located on ultrasound, which is precisely the setting her biomarker and hCG algorithm work addresses
- Pathology that may need addressing before a transfer: fibroids, adhesions, endometriomas and tubal disease, where she can assess the operative question and the cycle question in the same visit
- Blood pressure or metabolic risk factors before pregnancy: her preconception cardiovascular health research line makes this a discussable specialty rather than an off-topic question
