Meet Dr. Martha

Mae Sissa

Dr. Martha Mae Sissa was born and raised in Charleston, West Virginia. She holds a Bachelor of Science with honors in health and exercise science from Wake Forest University.   She received her medical degree from West Virginia University School of Medicine and then completed her pediatric residency training at the University of Alabama School of Medicine. It was after her training that she met her husband, Nick and moved to Houston to start her career in private practice and a family.  She is a Fellow of the American Association of Pediatrics. 

Prior to founding Maeville Pediatrics she worked for eight years in a busy pediatric private practice in Houston and Pearland. She has a fondness for breastfeeding, nutrition and mental health.  Dr. Sissa believes in the importance of the doctor-patient relationship and is thrilled to foster lifelong relationships with her patients.  When not at work, she is busy running after her 2 and 5 year old boys, Michael Paul and Nicholas, and spending time with her husband, Nick.  

Dr. Sissa became interested in breastfeeding medicine while nursing her own boys. She is pursuing her board certification in lactation medicine so she can help new moms navigate the intricacies and challenges of breastfeeding so they can meet their breastfeeding goals.
