Rhonda Coffelt is a full time Instructor of Chemistry and Natural Sciences Department Chair for Calhoun Community College on the Huntsville Campus. After serving in the U.S. Army as a musician (oboe, flute, sax and vocals), she earned her B. S. in Chemistry from Austin Peay State University, and an M.S. in Chemistry from Tennessee State University. She spent over 20 years in the Chemical and Environmental industries, serving as a Chemist, Trainer, Laboratory Director, Operations Manager, Facility Manager, and Director of Treatment and Transportation for several environmental consulting, transportation and hazardous waste treatment companies. She performed compliance training for over 10 of those years on Red Cross, OSHA, EPA, DOT and ISO14001 regulations. She was a Certified Hazardous Materials Manager and a Grade III wastewater treatment plant operator in Tennessee. She served in the Tennessee Army National Guard as a Petroleum Lab Specialist (NCOIC of a Mobile Fuel Testing Laboratory) during this time.

After numerous Environmental company buyouts, she used her year’s severance, adjunct teaching, and an NSF grant to earn a PhD in Biological Sciences (Biochemical/Molecular Research) from Tennessee State University. Rhonda’s research interests included: biological treatment of solvent contaminated wastewater, Astrobiology, and environmental toxicology. She has been teaching Chemistry on and off since 1988 and full time since 2005. She taught full time for Nashville State Community College from 2005 - 2016 and joined Calhoun Community College full time in fall of 2016.

Rhonda became a licensed practical nurse (LPN) in 2014, inspiring her daughter, Baylee to become a BSN, who practices nursing in Tennessee. She and Baylee hope to use their nursing skills on mission trips. She has two beloved cocker spaniels: Chloe and Sophia. She is a retired certified PADI Scuba Diving Instructor and a (former) ballroom dance champion. When not at Calhoun, Rhonda plays golf and Trivia in addition to singing and playing the flute, but not all at the same time! She is a Science fiction and forensic science fanatic and loves all things zombies.

Rhonda’s passion is teaching and loves nothing more than helping students understand how they learn and appreciate subjects (like Chemistry) that they thought they hated because they once had a bad teacher.
