Who is a Trunk Trainer?

A Trunk Trainer is a reliable, knowledgeable, friendly, excuse busting certified personal trainer that has a trunk of tricks to get you to exercise the way you should for the body you have today.  We travel (equipment in the trunk of our vehicles), we meet in the park (hook the TRX to a tree trunk), we use water therapy for injuries, we work with families and new mothers who can't bring their child to a traditional gym.  Our gym is open for personal training and offers a women's only gym membership 24 hours a day.  We let partners team up to keep costs down for getting individualized help.  We offer regular semi-private classes and free classes at our gym.  We offer a Corporate Wellness Program to sneak exercise into the middle of the day.  We find what makes you love to move and provide realistic fitness advice to all ages and bodies.

As a leading provider of personal training services we take pride in offering the best individualized programs to meet your health and wellness vision. We are dedicated to serving the needs of our customers each and every day.

With experience in working with seniors, soon-to-be mothers, children, teenagers, and athletes, whatever your age and fitness level, Trunk Trainers can help you get to where you want to be physically and mentally.

    • Leadership Development, ARMY

Born and raised on the Big Island, I grew up as active as possible. From martial arts, to wrestling, to JROTC, there was no off season for me. However, my true love for fitness came to me while in the Army. Taking classes in job-oriented fitness, lifestyle fitness, and recovery, my attraction towards the fitness industry continued to grow. Upon leaving the Army, I was lucky enough to work as a youth parkour and gymnastics coach at Hawaii Action Academy. Now, as a NASM certified Personal Trainer, I spend my days training adults at Trunk Trainers, and children at Kuleana Education as a Physical Education teacher. I am looking forward to getting further certifications in the areas of Nutrition, Injury Recovery, and body sculpting.

Grew up on the East coast of the USA. Began traveling to surf at a pretty young age. Starting off traveling to surf the Caribbean with my brother then central and South America & beyond.  I then worked on boats as crew to travel even further. Having visited and sailed around the Galapagos Islands, French Polynesia and Fiji before I was 18. I got turned onto amazing waves in the Polynesian island of Western Samoa in my 20’s. I got involved in a small surf camp in Samoa with a few friends. Eventually becoming more then ½ owner and building it up to a surf & game fishing resort (salanisurf.com) I ended up living down there surf guiding and managing the businesses for 10 years.  Some of the waves in Samoa are very heavy/dangerous at times and require a lot of fitness to surf on the big days. That is when I became obsessed with nutrition and training to help optimize my body to be the best in those demanding conditions. From that point on training and living healthy has been a huge part of my life. I moved to the big island in 2015, I continue to run the surf resort from afar as well as now run a big game fishing operation here (grandermarlin.com) I became a NASM CPT in February 2018 and look to further my certificates and fitness career so as to help people achieve their fitness goals and enjoy a healthy, flexible and functioning body.
