Natalie corona, B.SC., MS, ISSA - CPT

In just a few months, she felt stronger and healthier, both mentally and physically, and soon began helping other moms on their own fitness journeys. That passion led her to become a certified Personal Trainer and Nutritional Coach through ISSA in 2019 so she could support women and men locally as well.

Natalie’s coaching philosophy centers on functional training—building strength and confidence for everyday life while tailoring programs to each client’s goals. She loves helping people weave small, sustainable habits into their busy lives and celebrating their victories, especially the non-scale wins like having more energy, lifting heavier, or feeling stronger in daily activities.

Lauren Kurey, B.Sc., NASM-Group Trainer

For Lauren, fitness is more than just exercise—it's a journey of self-discovery and empowerment. She thrives on the sense of accomplishment that follows a grueling workout and takes immense pride in realizing she is capable of far more than she initially imagined. Fitness has also provided Lauren with a consistent routine that keeps her grounded, while the rewarding results—in both her mindset and her physique—continue to drive her forward.

Lauren’s journey into fitness began about six years ago when she felt dissatisfied with her physical appearance and overall health. Recognizing that she lacked the motivation and accountability to make lasting changes alone, she turned to group training. Lauren finds that group workouts push her to work harder, making the experience enjoyable thanks to a vibrant community of like-minded individuals who celebrate every win and understand the struggles.

Outside of the gym, Lauren is a dedicated 4th-grade teacher and a graduate of St. Xavier University, where she earned her Bachelor’s degree in Education. Whether she is in the classroom or the gym, Lauren loves being part of communities that inspire growth and foster meaningful connections.
