Originally from the North Star state and Land of 10,000 Lakes of Minnesota, Mary made the move to the Lone Star state of Texas (where there is just one natural lake…Caddo) while in high school. Her summers attending Camp Sakajawea in Apple Valley, MN and Camp Wabigonese in Brainerd, MN lead to an interest in the study of the natural world and ultimately to degrees in biology and chemistry at East Texas State University (now, Texas A&M University-Commerce). Her graduate studies focused on her interests in microbiology and genetics with a master’s thesis on antibiotic resistance and plasmids in Salmonella sp. She taught high school biology and chemistry for 7 years prior to joining NTCC in 1985, first as an adjunct instructor, and then as a full professor of biology and chemistry in 1987. She was awarded the doctorate degree from TAMU-Commerce in 1991 with a dissertation identifying factors related to community college student success in course work in anatomy and physiology.

Dr. Hearron teaches courses in general biology, microbiology, anatomy and physiology, genetics, nutrition and general and introductory chemistry. She has developed and taught online courses in anatomy and physiology, microbiology and genetics since 2010. In addition to her teaching responsibilities, she also serves as the Chair for the Division of Natural Sciences.

Her hobbies include gardening, oenology, travel and reading.
