“I have many different types of students,” said Halas-Liang of SDSU’s online program. “Many are personal trainers, but I also have wellness directors, MBAs, and nurses, looking to better develop their institution’s program. Some attend for CEUs and I do get the occasional person who decides to take the course to improve their life or is exploring a new degree and wants to gain some exposure to nutrition material before further investing.”

Students can choose from two certificate options:  Nutrition for Optimal Health and Wellness; and Nutrition for Optimal Health, Wellness, and Sports — with an emphasis in sports nutrition and performance. The five-week courses in each certificate program are online, so students can register at any time.

“I love going at my own pace but still gaining lots of material on nutrition,” said student Shelly Matthews. “I’ve been able to practice my knowledge in my everyday lifestyle, and I encourage others to become more informed about their nutritional diet so they can make the best choices for their lifestyle.”
