Who is Tatiana Chichilla from Jeopardy?

Tatiana Chichilla has built an impressive career combining science, medicine, education, and compassionate patient care. Originally from Mill Hall, Pennsylvania, she is a Certified Genetic Counselor (CGC) who specializes in oncology genetics and currently works with WellSpan Health in York, Pennsylvania. Her work focuses on helping patients understand inherited cancer risks, interpret complex genetic testing results, and make informed healthcare decisions for themselves and their families.

With a background spanning genetics research, university teaching, crisis counseling, precision medicine, and nonprofit advocacy, Chichilla brings an unusually broad range of experience to her profession. Her career reflects a commitment to making complex medical information accessible while supporting patients through some of the most significant healthcare decisions they may face.

Building a Career in Cancer Genetic Counseling

Since June 2022, Tatiana Chichilla has served as a Cancer Genetic Counselor with WellSpan Health, practicing through WellSpan Genetic Counseling at Apple Hill in York, Pennsylvania. Her clinical office is located at 25 Monument Road, Suite 160, where she works with individuals and families seeking guidance about hereditary health conditions.

As an oncology genetic counselor, Chichilla specializes in identifying inherited cancer risks and explaining what genetic testing results mean for patients. Rather than simply reviewing laboratory reports, she helps individuals understand the medical significance of genetic findings, discusses available screening and prevention strategies, and guides patients as they make decisions regarding future medical care.

A significant part of her clinical work has been associated with WellSpan’s Gene Health Project, an initiative designed to identify individuals who may carry inherited genetic conditions before disease develops. The program screens eligible participants for conditions including hereditary breast and ovarian cancer syndrome, Lynch syndrome, and familial hypercholesterolemia, allowing patients to pursue earlier surveillance and preventive care where appropriate.

Her role also extends beyond the individual patient. Because inherited genetic conditions often affect multiple family members, Chichilla helps patients understand how their results may impact parents, siblings, children, and extended relatives. She provides guidance on family communication and helps patients navigate conversations that can influence healthcare decisions across generations.

Strong Academic Foundations in Genetics and Medicine

Chichilla’s professional career is supported by extensive academic training in biology and genetic counseling. She attended the University of Pittsburgh from August 2016 through December 2019, earning a Bachelor of Science in Biology (Biological Sciences).

During her undergraduate years, she gained valuable teaching experience as an Undergraduate Teaching Assistant in Genetics between August and December 2018. The position allowed her to reinforce complex genetic concepts while developing communication skills that would later become essential in patient counseling.

Outside the classroom, she reportedly participated in the Genetic Counseling Club and the Pitt Blue & Gold Society, where she served as Vice President of Traditions. These activities demonstrated an interest in leadership and community involvement alongside her scientific studies.

She continued her education at The Ohio State University College of Medicine, completing a Master of Science in Genetic Counseling between August 2020 and May 2022. Graduate training provided advanced clinical experience while preparing her for board certification and professional practice in medical genetics.

Her master’s research focused on developmental genetics through a thesis titled “Characterizing Autism Spectrum Disorder in Children with Williams Syndrome via the Autism Spectrum Rating Scale.” The project examined behavioral characteristics associated with Williams syndrome and autism spectrum disorder, contributing to ongoing research into complex neurodevelopmental conditions.

Research, Education, and Crisis Counseling Experience

Before beginning full-time clinical practice, Chichilla accumulated experience across several fields that strengthened both her scientific knowledge and interpersonal skills.

From May 2021 through June 2022, she worked as a Student Research Assistant on The Ohio State University’s DCM Precision Medicine Project. Precision medicine aims to tailor healthcare using genetic, environmental, and lifestyle information, making the project closely aligned with her eventual clinical specialization in genetic counseling.

Alongside her research work, Chichilla also spent several years as a self-employed private tutor, working from March 2017 through March 2020. Tutoring allowed her to develop clear communication techniques and experience explaining difficult scientific concepts to learners with varying educational backgrounds.

Earlier in her career, she served as a Crisis Counselor with Pittsburgh Action Against Rape (PAAR) between November 2018 and July 2020. The position required empathy, active listening, crisis intervention skills, and emotional support for individuals experiencing traumatic situations.

Taken together, her experiences in education, research, tutoring, and crisis counseling created a unique professional foundation. They prepared her not only to interpret complex scientific information but also to communicate sensitive medical issues with compassion and clarity.

Supporting Families Through Hereditary Cancer Advocacy

Beyond her clinical responsibilities, Chichilla is actively involved with FORCE: Facing Our Risk of Cancer Empowered, a nonprofit organization dedicated to supporting people and families affected by hereditary cancers.

She became a Patient Advocate Leader with FORCE in October 2024, expanding her volunteer work by helping individuals navigate hereditary cancer concerns outside the traditional healthcare setting. In February 2026, she also became a Genetic Expert Leader, further strengthening her role within the organization.

Through FORCE, Chichilla organizes and moderates online support-group meetings that provide safe, welcoming spaces for participants to discuss inherited cancer risks, genetic testing, and family experiences. She also shares expert-reviewed educational materials and helps participants better understand available medical information.

Her advocacy work emphasizes informed decision-making and encourages families to communicate openly about hereditary conditions that may affect multiple generations. This volunteer commitment complements her clinical career by extending education and support beyond individual patient appointments.

Life Beyond the Clinic

While genetics and medicine define much of her professional life, Chichilla has also pursued several interests that reflect her creativity and commitment to community service.

She has reportedly participated in The Ohio State University’s Voices in Humanism initiative, a program that encourages healthcare professionals to develop empathy, compassion, and patient-centered communication alongside their scientific training.

Outside of healthcare, she enjoys complex cross-stitching, particularly intricate projects inspired by impressionist artwork. The detailed nature of cross-stitch provides a creative outlet requiring patience, concentration, and precision, qualities that also serve her well in genetics.

She has additionally volunteered as a LibriVox reader, contributing voice recordings for collaborative public-domain audiobook projects. The volunteer work reflects an ongoing interest in making educational and literary resources accessible to wider audiences.
