Allie Mendez

Allie Mendez

Events Specialist

Allie’s passion for water and the environment sprung up in her high school Environmental Science class while taking a field trip to a river. Using waders, field equipment, and water quality kits to determine the water’s health, she knew this was a field she had to be a part of. This passion only grew as she attended Concordia University-Wisconsin for her Bachelor of Science in Environmental Studies. While pursuing her education, she worked at Concordia’s Center for Environmental Stewardship and tutored for chemistry. She also interned at the Mequon Nature Preserve and Victory Garden Initiative and volunteered with the mussel monitoring program at Milwaukee Riverkeeper. In her free time, Allie enjoys reading, traveling, trying new crafty hobbies (currently embroidery), and drinking good coffee.

Shirley Aspinall

Shirley Aspinall

Communications Specialist

As a Milwaukee native since kindergarten, Shirley grew up enjoying any opportunity to play or spend time with family and friends outdoors, especially if it were in or around water. Witnessing a growing concern for the quality of our waters throughout her life while at the same time developing a passion for all things science, she realized combining these two areas of interest would be her lifelong pursuit. Having been on a challenging health journey the past 15 years, she is a passionate advocate for health and wellness, and attests strongly to how the health of our environment is essential to not only our individual health, but the overall health of the communities that live in it. Shirley studied Environmental Health and Water Quality at the Milwaukee Area Technical College, and currently has returned to study Chemical Technology and Teacher Education, while assisting with teaching Intercultural Communication courses. When not working or studying, Shirley is traveling, camping, kayaking, hiking, reading, puzzling, or painting.  She’s an avid thrill seeker, devoted to her meditation practice, and is working towards living self-sustainably in a tiny home with her partner, two cats, and 50+ houseplants.
