Melissa Holecek, Education Coordinator

Melissa is excited to have her dream job, as education coordinator, at the Water & Environmental Center (WEC). Melissa was born and raised in Walla Walla, but didn’t move back to the area until after attending college in Idaho. Environmental education has always been one of Melissa’s passions. She has worked as a Bleak Intern at Taylor Ranch Wilderness Field Station, environmental educator at the McCall Outdoor Science School, stream research technician at the Idaho State University Stream Ecology Center, and most recently as a middle school math and science teacher before coming to the WEC. Melissa enjoys being outdoors with her husband, Dean, and miniature schnauzers, Tiki and Henry. Sea kayaking, hiking, horseback riding, fly-fishing, mountain biking and skiing are just a few of her outdoor pursuits. Melissa also enjoys cooking, reading, and quilting.
