To My Dear Patients:
I’m leaving Kelsey-Seybold’s Cancer Center to pursue a specific subspeciality in Oncology. My last day here will be Oct. 15, 2021. For questions regarding transition of care, phone the Hematology/Oncology Department at 713-442-1081, weekdays 8 a.m. to 5 p.m. I greatly appreciate the privilege of helping care for your health and I am sad to say goodbye. Read my full letter here.

Fun Facts

The best advice Dr. Ko has ever received is “Take it one day at a time.”

Dr. Ko has traveled to many countries, but her favorite is Greece because of the good food, beaches, and islands.

Her guilty pleasure is watching Netflix reality shows.

Not everyone knows this about Dr. Ko, but she moved to the United States when she was 14 and since then has lived in Arkansas, North Carolina, New Jersey, New York, and Texas.

​I believe in educating my patients about their medical conditions so they will feel empowered and involved in a shared decision-making process. I also provide them with evidence-based care that will help guide an informed treatment decision. I truly enjoy getting to know my patients and their families and building strong, long-lasting relationships.
