Lisa Piagari, MS, RD, LDN
My teaching philosophy is to create a friendly, safe learning environment that allows for supervised exploration. I believe my role as an instructor is to motivate and empower the students’ learning through meaningful and practical experiences. Through hands-on experiences, classroom discussion, and even the use of humor, I hope to coach students to inspire their learning. I want them to feel that success includes good mistakes.
I am committed to giving students the tools they need to analyze information and situations, and effectively solve problems. The best approach to achieve these goals is using a blended-flip-the-classroom approach with project-based learning in the kitchenettes. This creates a great space for peer-to-peer collaboration and offers flexibility for me to offer personalized help and direction to students as they complete their work.
My educational background includes a Master of Science in Nutrition and Dietetics at Northern Illinois University while completing the AP4 field experience program, and a Master Online Teacher Certificate from the University of Illinois, Urbana-Champaign. Good nutrition knows no age. For decades, I’ve worked as a clinical dietitian in skilled nursing facilities while teaching online before it became the “new normal.” My motto is, "Healthy eating is a good habit!"
