Bartlomiej (Bart) Posnik, M.D.

Bartlomiej (Bart) Posnik, M.D., is board certified in hematology, internal medicine, and medical oncology. Raised by physical therapist parents, he was always interested in science and social studies. Dr. Posnik knew early he wanted to pursue health and medicine. He decided to become a medical doctor after working as an English-Spanish interpreter at a St. Louis free medical clinic. In medical school, he entered internal medicine to make a real connection with patients and help them through difficult diagnoses.

He is incredibly proud of completing his hematology/oncology fellowship as chief fellow at Chicago’s John H. Stroger, Jr. Hospital of Cook County. The clinical experience prepared him well to diagnosis and treat a broad range of hematology and oncology conditions. Dr. Posnik is extremely proud to be part of Texas Oncology. It is respected for providing top quality cancer care close to the comfort of home and family.

Dr. Posnik says the most exciting thing about cancer treatment is the pace at which it is evolving. Many cancers once considered fatal are now managed as chronic medical conditions. Treatment is becoming more individualized, based on a person’s unique cancer cells. This leads to more personalized treatment options and a decrease in potential side effects.
