Meet Heather

Headshot of Heather Feretta

Heather grew up on the island of Kauai, immersed in a healthy and active lifestyle, enjoying hiking, surfing, and competitive swimming and running. Later, she moved off the island to earn her bachelor’s degree in Kinesiology and Sports Psychology from Western Washington University. Heather also competed as a High Jumper on Western’s DII track and field team throughout her college career. Her lifestyle, studies, and athletics inspired her interest in personal training, so she became fully certified through the American Council of Exercise. 

Heather is passionate about sparking joy in others’ lives through movement. Her approach to fitness is rooted in functional movement patterns that nourish both the mind and body and cultivate feelings of inner and outer strength and confidence. She will provide you with training programs tailored to your unique goals that honor the development of biomechanical efficiency so that you can achieve long-term health, functioning, and strength through the movements you enjoy.

Meet Waylon

Waylon was born and raised on Kauai and graduated Western Oregon University with a BS in Exercise Sports Science. He worked at Oregon State University as an Adapted Physical Activity Coach, focusing on a motor skills fitness program for children with special needs. He also worked as a Corrective Exercise Technician at IndigoWellness Center, applying his personal training techniques for yoga practitioners and Scholarship athletes. After returning home to Kauai, he worked as a Physical Therapy Technician for 3 years at an outpatient clinic while simultaneously coaching youth sports and working 1 on 1 with clients around nutritional education and fitness performance. On his off time, Waylon spends time with family. If he’s not chasing around his nieces and nephews, he’s hiking a trail in Kokee, riding dirt bikes in Anahola or having a nice R&R day on the Southside.
