Elizabeth "Ann" Thyssen, DO, MS, FAAP

Dr. Elizabeth "Ann" Thyssen is a fifth generation Texan who grew up in Houston. She completed her medical degree and masters at the Texas College of Osteopathic Medicine in Fort Worth and then went on to train as a pediatrician in Corpus Christi, TX at Driscoll Children’s Hospital. Before joining Pearland Pediatrics, she practiced for six years as a pediatric hospitalist attending at Texas Children’s Hospital where she treated patients and taught medical students, residents, and fellows through Baylor College of Medicine. She has served on the board of the Texas chapter of the American Academy of Pediatrics, The Texas Pediatric Society. She is a doctor of osteopathic medicine (DO), so her medical school included training in osteopathic manipulative medicine (OMM). OMM includes an extra modality of diagnosis and treatment called osteopathic manipulative treatment or “OMT”. Osteopathy focuses on the body’s inherent ability to heal itself. Treatments are based on the principal that body structure determines function, and focus on optimizing alignment of structures to facilitate healthy functioning. For more on osteopathy and OMT, see www.osteopathic.org and www.acopeds.org/.  

Dr. Thyssen's pediatric interests include asthma, Love and Logic parenting, and patient and family centered care (PFCC). PFCC recognizes families and patients as owners of their healthcare and partners in decisions based on shared information. Her goal is to treat patients and their families the way she would have her own family cared for. 

She has two young children, a boy and a girl, and enjoys hiking, amateur gardening, and having adventures with her family. She is a founding member and vice president of the Catholic Healthcare Professionals of Houston.
