Diana Layton

Personal Trainer

Diana is a NASM-certified personal trainer. Her love of being physically active started at a young age. As a child, she spent summers camping, hiking, canoeing, and sailing with her family. The rest of the year was filled with martial arts training and doing anything outside. After years of participating in fitness classes she decided to take her love of fitness to the next level and become a personal trainer. She looks forward to helping others in their fitness journey and assisting them in achieving their goals.

“Fitness is not about being better than someone else… it’s about being better than you used to be.”

Caitlin Weiss

Personal Trainer

Caitlin grew up in Yakima, Washington as one of nine children who contributed to working on my family’s farm. It was there she learned the meaning of teamwork, perseverance, and discipline in the area of physical strength. Her unique upbringing spurred my passion to become a personal trainer and for that, she is very grateful for the opportunity to help others become strong and change the trajectory of their lives. As a result, Caitlin became a certified personal trainer in March of 2023 and specializes in women’s fitness. She enjoys every opportunity to connect with and meet new people so she can lead them down a path of health, happiness, and strength.
