Dr. Siedlecki received her B.S. in Chemistry and worked as a classically trained chemist in the aerospace industry before returning to school to pursue her life long dream of becoming a veterinarian, combining both science with the human-animal bond.

Dr. Siedlecki understands the worry and concerns that her pet owners have and spends the time necessary to explain their pet's disease and treatment options. She is passionate about treating lymphoma, as it is a disease responsive to chemotherapy. She takes great joy in providing all of her chemotherapy patients with a high quality of life. Dr. Siedlecki finds oncology, the study of cancer, extremely rewarding because of the rapport that develops between her clients and herself over a course of treatment.
