Mary joined HealthTree in 2022. She is now the AML & MDS Community and Education Manager. She is passionate about giving power to patients through knowledge and health education. If she can help one patient feel more confident participating in discussions with their healthcare team and making treatment decisions, she will feel like she has succeeded. When she isn't advocating for patients, she loves being an aunt, attending concerts, and experimenting with new recipes in the kitchen.

Dr. Hsieh is a hematologist oncologist out of the Children's Hospital of Los Angeles. Her research focuses on developing cellular therapy clinical trials for relapsed hematologic malignancies.
